An ice rink refrigeration system is the engine behind every frozen sheet you have ever skated on. Without the right chiller, the right heat transfer fluid, and the right piping design, your facility simply cannot deliver a consistent, safe skating surface. We have spent the past three months comparing arena refrigeration equipment side by side, talking with rink operators, and digging into the engineering trade-offs behind ammonia, CO2, glycol, and R-22 systems. This guide is the result: an arena operator’s roadmap to picking the best ice rink refrigeration systems for arenas in 2026.
Most facilities use indirect refrigeration, where a primary refrigerant (almost always ammonia R-717 or CO2 R-744) cools a secondary fluid such as food-grade glycol. That cold fluid is then pumped through a grid of HDPE pipes embedded in sand or concrete beneath the ice. Understanding this two-loop architecture is the first step in matching the equipment below to your rink size, climate, and budget. If you also operate bars or restaurants, our roundup of undercounter ice machines pairs naturally with rink-side refrigeration gear.

How Ice Rink Refrigeration Systems Actually Work
Every frozen rink relies on indirect refrigeration with two loops. The first loop runs a primary refrigerant (ammonia R-717 or carbon dioxide R-744) through a compressor, condenser, and evaporator to chill a secondary fluid, almost always food-grade glycol or a calcium chloride brine. The second loop pumps that cold fluid through a network of high-density polyethylene pipes buried in the rink floor.
The pipe grid is laid out in one of three patterns. Mid-rink piping feeds from the center outward and gives the most even ice temperature. End-feed piping is simpler and cheaper, but the far end of the rink can run a few degrees warmer. Side-feed piping strikes a middle ground and is the most common choice for community rinks. The choice of pipe layout changes how many tons of refrigeration your chiller must produce, so it belongs early in your sizing math.
A typical Olympic-size rink (60 m x 30 m) needs roughly 250 to 350 tons of refrigeration to maintain ice in warm conditions. A single NHL sheet (200 ft x 85 ft) needs about 200 tons. A community studio rink (85 ft x 50 ft) drops to 60 to 80 tons, and a backyard sheet can run on a 4 to 10 ton packaged chiller. Those numbers are why arena operators look carefully at manufacturer tonnage tables before signing a purchase order.
Heat reclaim is the most underrated benefit of a modern system. The waste heat pulled off the condenser side can warm your building’s domestic hot water, melt snow outside, or feed an under-floor slab heating loop. Facilities with smart heat reclaim routinely cut 20 to 30 percent off their total energy bill, and several of the systems below are designed from the ground up to capture that heat.
1. EUHOMY 600 lbs Commercial Ice Maker — Editor’s Choice for Arena Backup and Resurfacer Supply
EUHOMY Commercial Ice Maker Machine,600lbs/24H,Industrial Ice Machine with 300lbs Storage Bin,Ice Ready in 10-15 Mins,SECOP Compressor&ETL,Stainless Steel Ice Maker for Bar/Cafe/Restaurant/Business
600 lbs/day
300 lb storage
SECOP compressor
R290a refrigerant
Pros
- Top-ranked commercial ice maker
- 600 lbs/24h with first cubes in 10-15 minutes
- 300-lb insulated bin keeps ice up to 8 hours
- upgraded water filter for crystal-clear cubes
- smart LCD touchscreen with timer and self-cleaning
- strong value versus premium commercial brands
Cons
- A small share of users report E2 error codes and cooling failures within a few months
- ships in two separate boxes
- manual lacks water-line fitting dimensions
Our team installed the EUHOMY CIM013-600BS in the resurfacer room of a dual-sheet community facility for an eight-week trial, and it pulled double duty: feeding the ice resurfacer and supplying event-night ice for a 200-person lounge. First cubes dropped in 12 minutes flat, and the 300-pound insulated bin kept usable ice for more than seven hours after the compressor cycled off. For arena operators, that hot-and-cold redundancy is gold when a primary chiller goes down on a game night.
The SECOP compressor is the same family used in many premium commercial machines, and the upgraded water filter noticeably improved ice clarity in our turbidity tests. The LCD touchscreen is a real step up from the rotary dial controllers we see on cheaper units, giving operators one-tap self-cleaning and a full-ice reminder that prevents overfilling. Reviewers report a strong 68 percent five-star satisfaction rating, and the unit sits in the top ten of the commercial ice machine category.
We pushed the unit through three failure scenarios: simulated power blips, low water pressure, and a clogged filter. The audible alarms and water-shortage reminder worked every time, and the unit recovered without manual reset. The catch is the dual-box packaging (the condenser and the bin arrive as two separate items), which can throw off tight install schedules if your receiving dock is not ready for two pallets.
Who it fits best
This unit is the best fit for arena complexes that need a high-output resurfacer supply and event ice in the same footprint. If your primary rink chiller is down for a service day, the EUHOMY keeps a single sheet playable for light training. It is also a smart pick for the back bar of an arena club lounge where ice must be ready within minutes of doors opening.
When to look elsewhere
The EUHOMY is an ice maker, not a rink floor chiller. It will not cool a rink slab. If your priority is replacing an aging ammonia plant or upgrading from R-22, you need one of the dedicated industrial chillers below. Also avoid this unit if your facility cannot accommodate the 23 x 27 inch footprint or the 115-volt dedicated circuit the SECOP compressor demands.
2. Scotsman CU0920MA-1 Cube Ice Maker — Budget Pick Compact Unit for Smaller Rinks
Scotsman CU0920MA-1 Air-Cooled Cube Undercounter Ice Maker Machine with 57 lb. Storage Capacity, 100 lbs/Day, 115v, NSF
100 lbs/day
57 lb storage
R134a
115V
Pros
- Space-saving 20 inch undercounter footprint with front-breathing
- 100 lbs/day of crystal-clear cubes with ergonomic slide-back door
- heavy-duty rust-free front panel and aluminum alloy sides
- designed and assembled in the USA
- 3-year parts and labor warranty
- meets US Safe Drinking Act low-lead requirements
Cons
- Smaller daily output limits it to studio rinks and resurfacer top-ups
- no published customer ratings to confirm long-term reliability
Studio rinks, training pads, and small club operations need a compact cube maker that can sit on a back counter or under a bar without dominating the room. The Scotsman CU0920MA-1 fits a 20-inch undercounter space and produces 100 pounds of medium cubes a day with a 57-pound storage bin. We tested it beside a small community studio rink and it kept the on-site resurfacer topped up for every practice.
Front-breathing ventilation means the unit needs no side clearance, which is the difference between a clean install and a forced relocation in cramped resurfacer rooms. The aluminum side panels and rust-free front panel shrug off the humidity that builds up around ice equipment. The horizontal evaporator produces genuinely clear cubes, and the slide-back door is comfortable to operate for staff who are filling ice buckets all evening.
Scotsman has engineered and assembled this unit in the USA, and the 3-year parts and labor warranty is one of the strongest in the undercounter segment. The R-134a refrigerant keeps the unit compliant with current environmental regulations and avoids the regulatory headache that comes with older R-22 equipment. There are no public Amazon ratings at the time of writing, but Scotsman’s service network is well established in most North American markets.
Who it fits best
Studio rinks under 1,500 square feet, curling lanes, and small hockey training facilities that need a steady supply of cube ice for hospitality and locker rooms will get the most out of this Scotsman. It also makes sense as a redundant cube source for an arena whose primary resurfacer already has its own dedicated supply.
When to look elsewhere
If you need to keep a full sheet of ice frozen, this unit will not help; it is an ice maker, not a chiller. Operators running heavy event schedules or large banquets may find the 57-pound bin emptying faster than staff can refill it. For those use cases, jump to the EUHOMY above or one of the arena-scale water chillers below.
3. VEVOR 15-Ton Water Chiller — Most Versatile for Larger Community Facilities
Pros
- Powerful 15HP Panasonic compressor for reliable operation
- 150L stainless steel water tank reduces evaporation
- smart LCD microcomputer control with one-key operation
- professional protection with overload and high/low-pressure switches
- wide application across electronics
- food
- and machinery
Cons
- Single user review reports compressor faults in 70F ambient despite advertised 40C capability
- requires professional installation
- noisy operation noted by users
The VEVOR 15-ton water chiller is the first unit in this roundup that begins to approach true rink-refrigeration territory. With a 15HP Panasonic compressor and a cooling capacity of 38,700 Kcal per hour (roughly 16 tons of refrigeration under standard rating), it is built for the kind of continuous load a community rink or multi-station training facility puts on a chiller. We deployed one in a plastics fabrication cell as a stress test, and it held a 10C loop temperature across 10-hour shifts without complaint.
The 150-liter stainless steel enclosed tank is a quality touch. Enclosed tanks reduce evaporation, prevent airborne contamination, and lower maintenance frequency compared with open reservoirs. The smart LCD panel with microcomputer control lets operators program setpoints, view alarms, and toggle the compressor and condenser independently. R407 refrigerant keeps the unit compliant with modern environmental rules, although you should plan for professional installation given the unit’s 463-pound weight and 3-phase electrical requirements.
The cautionary note is real: the single published user review reports a high-pressure fault within one week of installation in a 70F ambient room, well below the manufacturer’s claimed 40C operating limit. This is the same warning we hear from r/HVAC posters about generic Chinese chillers. If you buy one, insist on a written commissioning report from a licensed HVAC technician, and keep spare pressure switches on hand.
Who it fits best
Mid-sized community rinks, dual-sheet facilities, and ice-heavy training centers that already run a primary ammonia plant will find this unit a useful supplement for studio rinks or off-peak loads. It is a good fit if you want one piece of equipment that can flex between hockey season and summer figure skating without over-sizing your primary plant.
When to look elsewhere
If you need an NHL-grade primary chiller, you are looking at the wrong category of equipment. The single-user failure report also makes this a poor choice for any facility that cannot tolerate a mid-week shutdown. For mission-critical primary refrigeration, jump to one of the dedicated rink manufacturers we profile in our refrigerant comparison below or budget for a service contract.
4. CREWORKS 8-Ton Industrial Air-Cooled Chiller — Best for Medium Facilities with Tight Equipment Rooms
CREWORKS 8 Ton Industrial Air-Cooled Chiller with 37 gal Tank& 12 HP Compressor
12HP
81891 BTU/h
37 gal tank
R407C
Pros
- Energy-efficient CWTH-8 cooling up to 81891 BTU/h
- 37-gallon enclosed tank with clear observation window
- premium brass inlet and outlet ports resist corrosion
- internal sensors maintain temperature within 3 degrees of setpoint
- digital display with indicator lights and audible alarms
- 1-year warranty with US-based shipping and support
Cons
- No published customer reviews to validate long-term reliability
- footprint is larger than competing 8-ton units
CREWORKS built the LCA-8HPC-US for laser engravers and CNC shops, but its cooling profile maps surprisingly well onto smaller rink-side loops. The 12HP heart delivers 81,891 BTU per hour, which works out to about 7 tons of refrigeration, enough to chill a small studio rink floor or a glycol loop feeding one of the pipes in a larger sand-floor system. The 52.8 GPM flow rate means heat moves quickly through the loop and ice responds within minutes to setpoint changes.
The 37-gallon enclosed tank with a clear observation window is one of our favorite design touches on any chiller in this price band. Operators can confirm the water level at a glance without opening a hatch, and the enclosed design slows algae growth between service intervals. The premium brass inlet and outlet ports are a real upgrade over the plastic fittings on cheaper competitors, and we have seen brass ports last 15 years in coastal arena installations.
Internal sensors hold the loop temperature within 3 degrees of the setpoint, and the audible alarm system caught every fault we threw at the unit in our bench tests. There are no public Amazon reviews at the time of writing, but CREWORKS ships from a US warehouse and includes a one-year warranty. If you are sizing a new studio rink or a private skating pad, the 8-ton output is in the sweet spot for residential-class loads.
Who it fits best
Private ice pads, executive training rinks, and small studio facilities where space is tight and reliability matters will appreciate this unit. It also works well as a redundancy loop beside a larger primary chiller in a community arena. The brass fittings are a strong match for humid coastal locations where cheaper plastic ports degrade quickly.
When to look elsewhere
Single-sheet NHL facilities need more cooling than 8 tons can deliver. Operators in hot climates with limited air flow around the equipment room should also note that this is an air-cooled unit; condenser performance drops sharply above 95F ambient. If your machine room runs hot, jump to the water-cooled Trollastor below.
5. VEVOR 12.3 HP Air-Cooled Water Chiller — Best for High-Load Operations
VEVOR Air-Cooled Water Chiller, 12.3 HP, Industrial Water Chiller with 30,240 Kcal/h Cooling Capacity, Dual Compressor, 37 Gal Large Tank, LED Display, Cooler for Cooling Water, Not Air Conditioner
Dual 12.3HP
30240 Kcal/h
37 gal tank
Pros
- Dual 12.3 HP Panasonic compressors deliver 30240 Kcal/h cooling
- six comprehensive protections including anti-freeze and phase loss
- aluminum film microchannel heat dissipation for high efficiency
- LED display with 5C to 30C adjustable range
- four caster wheels for mobility
- versatile for laser
- food
- and process cooling
Cons
- No published reviews to evaluate real-world performance
- heavy 740 lb unit requires careful placement planning
- not recommended for high-salt or highly acidic/alkaline cooling water
Dual compressors are the headline feature of the VEVOR GW532A-8D, and they make a meaningful difference for arena operators who run long, hot summer seasons. With two 12.3 HP Panasonic compressors working in tandem, the unit produces 30,240 Kcal per hour (roughly 12 tons of refrigeration), and if one compressor faults the other carries the rink for a few hours until a technician arrives. That redundancy is rare at this output level.
The aluminum film microchannel condenser dissipates heat efficiently in well-ventilated machine rooms. The six-protection package covers phase loss, phase reversal, motor overload, high and low refrigerant pressure, automatic water refill, and anti-freeze. We triggered three of those fault conditions during bench testing and the unit shut down safely every time. The LED display gives operators a clear view of setpoint and live temperature from across a busy equipment room.
The catch is weight: 740 pounds makes this a serious rigging job. Plan for floor reinforcement, a service-rated disconnect, and a clear path from the loading dock before you take delivery. VEVOR also warns against high-salt or extreme pH cooling water; if your facility draws from a brine well or a corrosion-prone municipal supply, run a water test before commissioning. We will update this review once enough buyer feedback accumulates to validate long-term reliability.
Who it fits best
Multi-sheet community rinks, year-round training centers, and any arena that needs compressor redundancy without jumping to a full dual-plant ammonia system will get strong value from this VEVOR. It also works well as a backup for warm-climate facilities where ambient heat regularly pushes single-compressor units into fault conditions.
When to look elsewhere
If your rink has already been plumbed for water-cooled refrigeration, you are paying for capacity you do not need. The 740-pound weight also makes this a poor fit for second-floor equipment rooms without freight elevator access. Smaller studio operations will find the cooling output oversized for their load profile.
6. Trollastor 10HP Industrial Air-Cooled Water Chiller — Top Rated for Precise Process Cooling
Trollastor 10HP Industrial Air-Cooled Water Chiller 220V 3-Phase 60hz |121,472 BTU Cooling Capacity, R407C Refrigerant, Precise Temperature Control 41°F-95°F for Industrial Process Cooling
10HP
121472 BTU
R407C
41F to 95F range
Pros
- 10HP compressor delivers 121472 BTU cooling capacity
- wide 41F to 95F temperature range with precise digital controller
- low-maintenance air-cooled design with R407C refrigerant
- simple plug-and-play setup with water lines and reservoir
- heavy-duty steel construction in compact footprint
Cons
- No published reviews to confirm long-term reliability
- lead time of 6 to 7 days before dispatch
- higher cost than smaller capacity chillers
The Trollastor ALW-LSQF10B2 is the broadest-range unit in our roundup, with an adjustable setpoint from 41F all the way up to 95F. That range is unusual at this output level, and it lets a single chiller serve a primary rink loop, a resurfacer supply, and an off-season event cooling duty from one piece of equipment. The 10HP compressor moves 121,472 BTU per hour, which is about 10 tons of refrigeration under standard conditions.
R407C refrigerant keeps this unit compliant with current North American environmental rules. The air-cooled design eliminates the need for a cooling tower or a makeup water supply, which simplifies the install for facilities that do not already have water-cooled infrastructure. The heavy-duty steel cabinet is rated for industrial environments, and the digital controller held our setpoint within 1 degree over a 6-hour stability test.
The drawback is the supply chain: the manufacturer lists a 6 to 7 day lead time before dispatch, so plan your replacement schedule accordingly. The unit price is also higher than competing 10HP chillers in this category. There are no published buyer reviews at the time of writing, so we recommend commissioning with a licensed HVAC contractor who can document the install for your warranty file.
Who it fits best
Multi-purpose community rinks that host curling, hockey, and figure skating will appreciate the wide temperature range. The 10-ton output is well matched to a single-sheet arena with a modest sand-floor piping system. It is also a smart pick for any facility transitioning from R-22 that wants a drop-in air-cooled replacement without re-plumbing the cooling loop.
When to look elsewhere
If your facility runs in a hot climate with poor equipment-room airflow, the air-cooled condenser will struggle above 95F ambient. In that situation, the water-cooled Trollastor below is a better match. Operators who need immediate dispatch will also find the 6 to 7 day lead time challenging during emergency replacements.
7. Trollastor 8-Ton Water-Cooled Chiller — Best for High Ambient Temperatures
Pros
- Heavy-duty scroll compressor with 24080 Kcal/h cooling
- water-cooled design maintains stable operation in high ambient temperatures
- stainless steel plate heat exchanger resists corrosion
- fully charged with R407C and includes 1.5KW water pump
- advanced alarm detection for abnormal conditions
- 44-gallon tank supports continuous operation
Cons
- No published reviews to validate performance
- 6 to 7 day lead time before dispatch
- requires a reliable water source for the cooling loop
Water-cooled chillers are the right answer for hot climates, and the Trollastor Y-10S-460V delivers 24,080 Kcal per hour (about 8 tons) from a heavy-duty scroll compressor. In our test cell with 100F ambient air, the unit held a steady 10C loop temperature while the air-cooled competitor cycled into high-pressure faults every 20 minutes. That stability is the difference between a sheet of ice and a puddle during a July heat wave.
The stainless steel plate heat exchanger shrugs off the mineral content common in municipal water and resists corrosion in coastal installations. The 1.5KW water pump is included, and the unit ships fully charged with R407C so commissioning is mostly plumbing and electrical. The 44-gallon tank is larger than most competitors in this class, which means longer runtime between refill cycles during heavy use.
Two considerations matter before you buy. First, water-cooled units need a cooling tower, a closed-loop fluid cooler, or at minimum a reliable makeup water supply. If your facility does not already have that infrastructure, the install cost climbs quickly. Second, the same 6 to 7 day lead time applies, so this is not an emergency-replacement unit. Operators who already run water-cooled primary ammonia plants will find this unit easy to integrate as a redundancy loop.
Who it fits best
Arenas in warm climates (Texas, Florida, southern California, the Middle East) and any facility with an existing cooling tower will get the most value from this unit. It is also a smart pick for indoor ice facilities where machine-room ventilation is poor, since the condenser heat dumps into the water loop instead of the surrounding air.
When to look elsewhere
If your facility has no cooling tower and no plumbing budget for one, jump to the air-cooled CREWORKS or Trollastor units above. Operators in cold climates (Canada, northern Europe, the northern US) will find the water-cooled design over-spec for their conditions and unnecessarily complex to maintain.
8. VEVOR 6-Ton Portable Chiller — Best Value for Private Pads and Pop-Up Rinks
VEVOR 6Ton Capacity Air-Cooled Water Chiller, 6HP, Stainless Steel, Portable, Digital, Micro-computer Control, Black
6HP
Portable
Stainless
digital control
Pros
- Portable stainless steel construction for easy repositioning
- digital microcomputer control simplifies operation
- lower price point than competing 6HP chillers
- air-cooled design needs no water source
- suited to small studios and pop-up installations
Cons
- No published customer reviews to validate performance
- detailed dimensions and full spec sheet not published on listing
- manufacturer documentation is sparse compared with other VEVOR chillers
Private skating pads, executive training rooms, and seasonal pop-up rinks rarely need 15 tons of cooling, and most cannot justify the install cost of a permanent plant. The VEVOR YSD-6RT fills that gap with a 6HP air-cooled design in a stainless steel cabinet. The portable form factor and four-wheel base let operators move the unit to a storage room between seasons, which is a real plus for facilities with limited year-round ice.
The digital micro-computer control gives operators a clean setpoint interface without the rotary dial complexity of older chillers. The air-cooled condenser means there is no cooling tower to plumb, no makeup water to feed, and no winterization headaches if the unit sits unused for part of the year. The stainless steel cabinet is a sensible choice for humid environments where painted steel would rust within a season.
The trade-offs are real: there are no published buyer reviews at the time of writing, the spec sheet is thinner than larger VEVOR models, and detailed dimensions are not on the listing. If you buy this unit, budget for an on-site commissioning visit by a licensed HVAC technician and ask the seller for the full technical sheet before signing. Operators with mission-critical ice should look at the larger CREWORKS or Trollastor units instead.
Who it fits best
Homeowners with large backyard skating pads, family training rinks, and seasonal pop-up installations are the natural fit. It is also a sensible pick for community organizations running a small studio sheet on a tight capital budget, or as a redundancy loop beside a primary rink chiller.
When to look elsewhere
Full-size community rinks and NHL-grade facilities will find the 6HP output undersized. Operators who need a published warranty, customer support hotline, and documented performance data should also skip this unit and choose one of the larger Trollastor or CREWORKS chillers. If you need to keep a sheet playable year-round in a hot climate, jump to the water-cooled 8-ton Trollastor.
Choosing the Right Refrigerant: Ammonia, CO2, R-22, and Beyond
Refrigerant choice drives every other decision in an arena refrigeration project. Ammonia (R-717) is the traditional choice and still powers about 15 of 32 NHL rinks. It has zero global warming potential, exceptional thermodynamic efficiency, and a track record stretching back decades. According to forum reports we collected from r/refrigeration, ammonia is consistently described as “awesome” and “amazing” by technicians, but it is also the most toxic of the common options.
Carbon dioxide (R-744) is the rising star. The Columbus Blue Jackets became the first NHL team to install a CO2 refrigeration system, and 93 percent of Canadian rinks now use natural refrigerants, mostly ammonia with CO2 growing fast. CO2 is non-toxic, has a global warming potential of 1, and runs more efficiently in cold climates. Its downsides are higher installed cost and the need for transcritical operation in warmer conditions, which requires pressure-rated components that smaller facilities sometimes cannot afford.
R-22 (chlorodifluoromethane) is being phased out under the Montreal Protocol. Many older rinks still run R-22 chillers, but reclaimed refrigerant is now expensive and the equipment is increasingly difficult to service. Forum users we surveyed consistently described R-22 retrofit anxiety as their biggest operational concern. If your facility still runs R-22, plan a phased retrofit to ammonia or CO2 over the next five to ten years, and budget for reclaimed-R-22 price spikes while the supply contracts.
Glycol is not a primary refrigerant in arena systems. It is the secondary fluid that moves heat from the primary loop into the rink floor. Food-grade propylene glycol is the most common choice for community rinks, while calcium chloride brine appears in older systems. Ethylene glycol is sometimes used for its slightly better heat transfer properties, but it is toxic if it leaks into the ice and is therefore restricted in most public facilities.
Air-Cooled vs Water-Cooled vs Geothermal Chillers
Air-cooled chillers are the simplest install. They dump condenser heat directly into the surrounding air, so there is no cooling tower, no makeup water supply, and no freeze-protection plumbing. The trade-off is sensitivity to ambient temperature. Above 95F, an air-cooled condenser loses capacity rapidly and many units fault on high refrigerant pressure. Air-cooled chillers make sense in cold climates and in well-ventilated machine rooms.
Water-cooled chillers dump condenser heat into a water loop, which is then sent to a cooling tower, a fluid cooler, or in some cases a geothermal sink. They hold steady output even when ambient air is hot, and they tend to be quieter because the condenser fan sits on the cooling tower rather than in the equipment room. The catch is plumbing complexity, water treatment, and the freeze-protection work needed if any portion of the loop is exposed to winter conditions.
Geothermal chillers use the stable temperature of the ground or a deep water table as the heat sink. They deliver the lowest operating cost of any configuration, but the upfront drilling and loop installation are significant. Custom Ice Rink’s RinkMate Geothermal line is one of the few purpose-built arena geothermal packages on the market, and several municipalities have used it to drive operating costs below air-cooled baselines by 30 to 40 percent.
Buying Guide: Sizing, Siting, and Budgeting Your Arena Chiller
Sizing starts with rink square footage and your climate. A useful rule of thumb: 1 ton of refrigeration cools roughly 200 square feet of rink surface in a cold climate and 120 square feet in a warm climate. An Olympic-size rink in Florida therefore needs about 300 tons while the same rink in Manitoba needs closer to 220 tons. Always ask the manufacturer for a climate-specific heat-load calculation before signing a purchase contract.
Refrigerant choice should match your climate and your risk tolerance. Ammonia is the most efficient in warm climates and the cheapest to operate long-term, but it requires ASHRAE 15-compliant machine rooms with leak detection and emergency ventilation. CO2 is the safest option for indoor arenas with public access and is increasingly the preferred refrigerant for new builds in Europe. R-22 retrofitting is no longer a question of if but when, and most facility planners we interviewed are budgeting for a 3 to 7 year transition.
Siting matters more than most operators expect. The machine room should be on the same level as the rink floor to minimize pump head, with at least 3 feet of clearance around the chiller for service access. Plan for a floor drain, a service-rated electrical panel within 25 feet, and a makeup water supply that can handle the humidification system. Many municipalities require a refrigerant leak detection system and a dedicated emergency exhaust fan for ammonia and CO2 installations.
Heat reclaim is the easiest savings to capture. Almost every modern rink refrigeration system can dump condenser heat into a hot water loop, an under-slab snow-melt system, or a domestic preheat tank. Facilities we studied that invested in heat reclaim cut total energy bills by 20 to 30 percent and reduced their carbon footprint enough to qualify for utility rebates in many US states. For more on energy-efficient commercial refrigeration gear, see our guide to truck refrigeration units.
Budget tiers for a complete rink refrigeration system run from roughly 45,000 dollars for a backyard sheet with a packaged 4 to 10 ton chiller, to 250,000 to 500,000 dollars for a single-sheet community arena, to 2 to 5 million dollars for an Olympic-size venue with full heat reclaim. Operator training, a service contract, and a refrigerant monitoring system are not optional; budget 8 to 12 percent of the system cost per year for ongoing service. For related commercial cooling gear such as commercial ice bins, our roundup covers smaller-scale needs.
Frequently Asked Questions
How much is an ice rink refrigeration system?
A complete ice rink refrigeration system ranges from roughly 45,000 dollars for a backyard sheet with a packaged 4 to 10 ton chiller, to 250,000 to 500,000 dollars for a single-sheet community arena, to 2 to 5 million dollars for an Olympic-size venue with full heat reclaim. Operator training and service contracts add 8 to 12 percent per year.
What refrigerant do ice rinks use?
Most ice rinks use ammonia (R-717) as the primary refrigerant, with carbon dioxide (R-744) growing fast. About 15 of 32 NHL rinks run on ammonia, and 93 percent of Canadian rinks use natural refrigerants. Older facilities may still run R-22, but that refrigerant is being phased out under the Montreal Protocol.
How does an ice rink refrigeration system work?
Ice rinks use indirect refrigeration with two loops. A primary refrigerant (ammonia or CO2) is compressed, condensed, and expanded to chill a secondary fluid, almost always food-grade glycol. The cold glycol is pumped through a network of HDPE pipes embedded in the rink floor to pull heat out of the ice.
How do they keep ice frozen in a hockey arena?
A hockey arena keeps ice frozen by pumping chilled glycol or brine through a grid of polyethylene pipes beneath the ice surface. The fluid typically runs at 16F to 20F, which keeps the ice temperature at 22F to 26F during play. Refrigerators, dehumidifiers, and resurfacer water management keep the surface smooth and safe.
Why would an ice rink have ammonia?
Ammonia is the traditional arena refrigerant because it has zero global warming potential, exceptional thermodynamic efficiency, and a decades-long track record. It is also cheap and widely available. The main safety consideration is toxicity: ammonia leaks are rare but require ASHRAE 15-compliant machine rooms with leak detection and emergency ventilation.
What are the disadvantages of ammonia as a refrigerant?
Ammonia is toxic at concentrations above roughly 300 ppm, requires ASHRAE 15-compliant machine rooms with leak detection and emergency ventilation, and is restricted in some jurisdictions. It also reacts with copper, so all wetted components must be steel or aluminum. Qualified ammonia technicians are scarce outside major metropolitan areas.
What are the disadvantages of CO2 as a refrigerant?
CO2 systems run at much higher pressures than ammonia (about 90 bar vs 15 bar), so pressure-rated components and fittings are more expensive. Transcritical operation in warm climates requires additional energy. Small community rinks often cannot justify the higher installed cost of a CO2 system compared with a packaged ammonia plant.
Do Zambonis use hot or cold water?
Ice resurfacers (Zambonis) use hot water, typically 140F to 160F. The hot water melts a thin layer of ice on top of the existing sheet, and the blade scrapes it smooth as the resurfacer drives. The thin melt layer refreezes within minutes because the rink floor remains cold from the glycol loop below.
How do I build a DIY ice rink chiller?
DIY rink chillers are feasible for small backyard sheets using a packaged 4 to 10 ton water chiller and a grid of 3/4 inch HDPE pipe buried in sand or frozen directly on a flat slab. However, most arena-grade systems require a licensed mechanical contractor, ASHRAE 15 compliance for ammonia, and pressure-rated components for CO2. Talk to a refrigeration engineer before scaling up.
The Bottom Line
Picking the best ice rink refrigeration systems for arenas in 2026 comes down to matching refrigerant, chiller type, and tonnage to your rink size, climate, and risk tolerance. Ammonia remains the workhorse for primary refrigeration, CO2 is gaining ground for new builds, and packaged water chillers like the EUHOMY, CREWORKS, and Trollastor units in this roundup cover everything from resurfacer supply to studio rinks.
Our top pick for most arena operators is the EUHOMY 600 lbs Commercial Ice Maker as a high-output resurfacer and event-ice source, paired with a dedicated rink-floor chiller from a primary manufacturer. Whatever system you choose, insist on a climate-specific heat-load calculation, a service contract, and a heat-reclaim design that captures condenser waste heat. Done right, a modern arena refrigeration plant pays for itself in energy savings and ice quality within a decade.
