R290 Refrigerant Grade Propane Information

R290 is a High Purity Propane (C3H8) used in refrigeration that has become increasingly popular due to the reduced ozone depletion and global warming potential and improved thermodynamic properties over traditional refrigerant products.  R290 Propane is non-toxic, natural, un-odorized, high quality, low moisture , low cost solution for compliance with new refrigeration requirements.

What is hydrocarbon refrigerant?

Hydrocarbon (HC) refrigerants are natural, nontoxic refrigerants that have no ozone depleting properties and low global warming potential. Hydrocarbons are one of the most climate-friendly and cost-effective refrigerants to cool and freeze.

R290 (HC) refrigerant is highly refined propane that is a safe, environmentally friendly alternative for the hydrofluorocarbon (HFC) refrigerants R134a in refrigerator applications and R404a in freezer applications.

Why is hydrocarbon refrigerant better?

Current HFC Refrigerants (R134a and R404a) have extremely high Global Warming Potential (GWP) that is harmful to the environment. GWP is the relative measure of how much heat a greenhouse gas traps in the atmosphere. The lower the GWP the better a substance is for the environment. By comparison, R290 Hydrocarbon has a very minimal GWP.

R290’s thermodynamic properties are superior to both R134a and R404a. R290’s heat capacitance is approximately 90% greater than R134a and 140% greater than R404a with lower viscosity. This means that R290 can absorb more heat, faster, resulting in quicker temperature recovery and lower energy consumption.
