R134a is a HFC, used in automotive air conditioning and as a replacement for R12 and R22 in medium and high temperature refrigeration applications, such as commercial and domestic refrigeration and chillers.
R404a Refrigirant Gas
R404A is a HFC blend, used as a replacement for R502 and R22 in low and medium temperature refrigeration applications. Although it is a popular refrigerant, R404A is under great scrutiny due to its high Global Warming Potential (GWP). This has led to an increased focus on lower GWP alternatives such as R407F and R407A, along with newer alternatives such as R448A and R449A.
R407a Refrigirant Gas
R407A is a HFC blend, used as a replacement for R22 and R404A in low and medium temperature supermarket applications. Due to its moderate Global Warming Potential (GWP) it is also considered as an interim replacement for R404A and R507 in existing and new applications.
R410a Refrigirant Gas
R410A is a HFC blend, used mainly in air conditioning systems; it may also be used as an alternative to R13B1 in low temperature refrigeration.
R507 Refrigirant Gas
R507 is a HFC blend, used as a replacement for R502 and R22 in low and medium temperature refrigeration. With a Global Warming Potential (GWP) of 3985, R507 is under similar scrutiny to R404A.
