Refrigerant R513A


R513A refrigerant, with zero ozone-destruction potential (ODP) and low global warming potential, is used to replace R134a refrigerant in air conditioning or medium temperature commercial refrigeration systems, including direct expansion and centrifuges. The R513A refrigerant has the same energy efficiency as R134a refrigerant for both new system installation and existing system renovation, achieving the best balance between high energy efficiency and environmental sustainability.


R513A Refrigerant steel cylinder is a pressure container. Keep it away from fire, heat sources, 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.


As a widely used medium temperature refrigerant, R513A has good comprehensive performance. It is mainly used in medium temperature loop of overlapping system, medium temperature application of direct expansion system for commercial and industrial use, chiller, air conditioning and heat pump, installation of new equipment, and transformation of existing system.
