R508B
R508B is an HFC gas and an environmentally friendly azeotropic refrigerant that does not contain CFC and HCFC substances that destroy the ozone layer. It is currently recognized and recommended by most countries as the mainstream ultra-low temperature environmentally friendly refrigerant. It is widely used in new refrigeration equipment (ultra-low temperature), Cryogenic) on the initial installation and re-addition during the repair process.
As a widely used ultra-low temperature refrigerant, due to the good comprehensive performance of R-508B, it becomes a very effective and safe alternative to CFC-13, R-503, and HFC-23, mainly used in environmental test chambers/equipment (Heat and cold shock testing machines), freeze dryer/freeze dryer, ultra-low temperature refrigerator or freezer, blood bank refrigerator, biochemical test chamber and other cryogenic equipment (including scientific research refrigeration, medical refrigeration, etc.), are more commonly used in these cascades Low-temperature level of the refrigeration system.
