CO₂ transcritical and cascade refrigeration systems — supermarket, cold storage and industrial
CO₂ (R744) is the fastest-growing natural refrigerant — GWP of 1, non-toxic and increasingly efficient thanks to parallel compression, ejectors and adiabatic gas coolers. ColdMatch sources transcritical booster racks, subcritical cascades and full turnkey CO₂ plants for supermarkets, cold storage and industrial process.
What ColdMatch delivers
- Transcritical CO₂ booster racks with parallel compression and ejectors
- NH₃/CO₂ and HFC/CO₂ cascade plants for –40 to –55°C IQF and blast
- Adiabatic and evaporative gas coolers for hot-climate CO₂ performance
- Heat recovery from CO₂ discharge for tap water, space heating and process
- Supermarket packs, industrial racks and modular CO₂ chillers
Frequently asked questions
Does CO₂ work in hot climates?+
Yes — modern transcritical racks with parallel compression, ejectors and adiabatic gas coolers match or exceed HFC efficiency even at 40–45°C ambient. ColdMatch sources references from the Middle East, India and Southern Europe.
CO₂ or ammonia for cold storage?+
Ammonia usually wins above ~500 kW single site; CO₂ wins for distributed, modular or supermarket-style loads and for owners without PSM/ammonia operator capability.
Can CO₂ recover heat?+
Yes — CO₂ discharge temperatures of 90–120°C make heat recovery for hot water, space heating and process one of the strongest OPEX levers.
