WESTRON R410a gas is a Non-Ozone Depleting, Non-Toxic, Nonflammable near Azeotropic blends of two Refrigerants namely R-125 (50%) and R-32 (50%). It is developed for Medium temperature Refrigeration applications, Residential and Commercial Air-conditioning applications like small Chillers and, Heat pumps, Dehumidifiers, etc.
Westron R 410A refrigerant has been proved as a better Refrigerant than R 22 because, during various tests, 5 to 6% Higher Energy Efficiency Rating (EER) compared with R-22. This makes the OEM manufacturers to design the Compact Air Conditioning Equipment & that is the reason Millions of Compact Air-condition units are Sold around the World where Westron R 410A is used as Refrigerants.
Westron 410A refrigerant gas can be used with Polyolester (POE) and not with Mineral Oil or Alkyl Benzene Lubricant since it is not miscible with Refrigerants. POE Oil absorbs moisture quickly when it is exposed to the atmosphere. Anyways handle this very carefully and avoid prolonged exposure to air.
