Briton Refrigerant R170

Briton Refrigerant R170 (Ethane)

C2H6

Briton R170 is refrigerant grade ethane. It is a natural, or “not in kind” refrigerant suitable for use in very low temperature refrigeration applications. R170 is non-toxic with zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming Potential). It is a flammable refrigerant and therefore not suitable for retrofitting existing fluorocarbon refrigerant systems. Briton R170 (Ethane) is supplied as a compressed liquid in cylinders and ISO tube skids and as a cryogenic liquid in T75 cryogenic isocontainers for international transport. It is generally used in very low temperature industrial refrigeration applications and is a replacement for R23 and R5088.
