Refrigerant R455A


The refrigerant R455A is an HFO mixture with a low global warming potential (GWP). R-455A is a mildly flammable non-azeotropic mixture that can be used as a substitute for low, medium and high temperature applications in new systems. It offers tight capacity matching with R-404A, extended operating range, and high energy efficiency compared to propane or air conditioning refrigerants.


R455A refrigerant steel cylinder is a pressure container. Keep it away from fire, heat and direct exposure to sunlight. Usually, store it 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.


R455A, as a medium to high temperature refrigerant widely used today, is mainly used in commercial refrigeration cryogenic applications and can be used in many areas of the HVACR industry. Suitable for small charging, plug-in cabinet, condensing unit and freezer and freezer unit, small chiller, heat pump and chiller.
