Many widely used refrigerants have high Global Warming Potential (GWP) and/or degrade into PFAS (‘forever chemicals’), which accumulate in the environment and can be toxic. Our HPUs utilize a natural refrigerant and unlocks increased performance due to our proprietary design.
CO₂ stands out as a natural refrigerant for its minimal climate and health impact, regulatory resilience, safety, insurance and operational benefits making it the gold standard for sustainable refrigeration.
