CO2 Refrigeration

Future Proof with CO2 Refrigeration Systems

CO2 refrigeration systems are a natural, low global warming potential (GWP), sustainable alternative to using synthetic refrigerants. With recent regulations to phase out HFCs, CO2 systems enable you to get ahead of the mandates for environmental protection and future-proof your systems.
