What is a Maxron R290?
R290 is propane, a natural hydrocarbon refrigerant. It is used in commercial plug-in coolers, display cabinets, ice machines and some small ACs. It has excellent efficiency and very low GWP, but small charges and strict safety practice are needed.
Its global warming potential (GWP) is 3 on the IPCC AR4 scale, and its ASHRAE safety class is A3 (highly flammable). Systems on R290 normally use the oil the compressor maker specifies. Therefore, always use the refrigerant and oil shown on the equipment nameplate.

How do I store refrigerant cylinders?
Upright, cool, shaded and away from heat and flames.
Should old refrigerant be vented?
No. Recover it into a recovery cylinder.
