Refrigerant R508B


Refrigerant R508B is an environmentally friendly azeotrope refrigerant that does not contain CFCS and HCFCS that destroy the ozone layer. It is a mainstream ultra-low temperature environmentally friendly refrigerant recognized and recommended by most countries in the world. It is widely used in the initial installation and re-addition in the maintenance process of new refrigeration equipment (ultra-low temperature, cryogenic).


R508B Refrigerant steel cylinder is a pressure 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.


As a widely used ultra-low temperature refrigerant, R508B is mainly used in environmental trial box/equipment (hot and cold impact testing machine), freeze-drying machine/freeze-drying machine, ultra-low temperature refrigerator or freezer, blood bank refrigerator, biochemical test box and other cryogenic equipment (including scientific research refrigeration, medical refrigeration, etc.). It is commonly used in the low temperature grade of these overlapping refrigeration systems.
