Refrigerant R454A


R454A Low Global Warming Potential (GWP) refrigerant is a mildly flammable refrigerant with low global warming potential (GWP) used to replace R-404A in new equipment designs. It is a low GWP hydrofluoroolefins (Hfos) based refrigerant with balanced performance, It can be used as an alternative to R404A in positive displacement, direct expansion, low and medium temperature commercial and industrial applications.


R454A Refrigerant steel cylinder is a pressurised container. It should be kept away from fire, heat and direct exposure to sunlight. It is usually stored in a cool, dry and ventilated warehouse. When handling, light loading and unloading should be carried out to prevent cylinder and valve and other accessories from damage.


R454A is a medium to high temperature refrigerant widely used today in: supermarkets, distributed systems, walk-in cold rooms/freezers, condensing units (e.g. in food service), cold storage, stand-alone systems.
