R290 Refrigerant Advantage
R290 (propane) is a natural hydrocarbon refrigerant with an extremely low GWP of just 3, making it a forward-looking choice for environmentally conscious refrigeration system design. It offers excellent thermodynamic efficiency and is compatible with common mineral and polyol ester (POE) lubricating oils. Systems using R290 help operators meet increasingly stringent environmental regulations and sustainability goals.
