R290 refrigerant gas also called Propane, is a highly pure liquefied petroleum Propane gas globally used as an environmentally friendly refrigerant gas.
It is a hydrocarbon with less harmful fluorocarbon than other alternative refrigerant gases.
It is one of the highly burnable but low GWP gas that has higher efficiency.
In addition, the R290 refrigerant ODP value is 0.
R290 refrigerant is the best functional replacement of them and others CFC and HFC refrigerants alternative.
It is very famous and common as a replacement for typical refrigerants and air condition units such as R-22.
