Refrigerant Gas R448A


R-448A has advantages over R-404 in super refrigeration systems, with lower energy consumption and more environmental protection. As R448A belongs to HFO type non-azeotropic environmental refrigerant, it is the mainstream low temperature environmental refrigerant recognized and recommended by most countries in the world at present, and is widely used in the initial installation and re-addition in the process of maintenance of new refrigeration equipment.


R448A refrigerant steel cylinder is a pressurized container. Keep it 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.


R448A is a widely used medium and low temperature refrigerant, often used in cold storage, food refrigeration equipment, Marine refrigeration equipment, industrial low temperature refrigeration, commercial low temperature refrigeration, transportation refrigeration equipment (refrigerated truck, etc.), refrigerated condensing units, supermarket display cabinets and other refrigeration equipment.
