A-weighted emission sound pressure level is below 70 dB(A)
R290 is a refrigerant-grade propane used on a wide range of commercial refrigeration and air
conditioning units. A highly pure propane, it has a low environmental impact and nominal global
warming potential (GWP), meaning it possesses no qualities that can destroy the ozone layer. R290
also is the preferred hydrocarbon alternative of the Environmental Protection Agency (EPA),
substituting more harmful fluorocarbon refrigerants like R22, R134a, R404a and R502.
Units with R290 can only be maintained and repaired by authorized technicians who are
properly trained and certified.
