Refrigerant R508A


R508A is an environmentally friendly azeotrope refrigerant completely free of CFCS and HCFC substances that damage the ozone layer. It is a mainstream ultra-low temperature environmentally friendly refrigerant recognized and recommended by most countries in the world at present. It is widely used in the initial installation and re-addition in the maintenance process of new refrigeration equipment (ultra-low temperature, cryogenic).


R508A refrigerant steel cylinder is a pressurized 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.


As a widely used ultra-low temperature refrigerant, R508A is a very effective and safe alternative to CFC-13, R503 and HFC23 due to its good comprehensive performance. Mainly used in environmental test box/equipment (hot and cold impact testing machine), freeze-drying machine/freeze-drying machine, ultra-low temperature refrigerator or freezer, blood bank refrigerator and other cryogenic equipment (including scientific research refrigeration, medical refrigeration, etc.), commonly used in these overlapping refrigeration system of low temperature grade.
