ABOUT A.S. Trust & Holdings Inc

A.S. Trust & Holdings has developed a line of refrigerants based on a ground-breaking blend of pure hydrocarbons. The unique formula of the initial product has been designated R441A by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) since January 2011. R441A is one of the first hydrocarbon refrigerants to be approved for sale in the United States by the U.S. Environmental Protection Agency under the Significant New Alternative Policy (SNAP) for use in household refrigerators and freezers.

R441A operates with mineral oil and can be used as a direct replacement in residential appliances, commercial refrigeration units and automotive cooling systems designed for R12 and R134a.

The company has also created a second formulation of blended pure hydrocarbons, designated as R443A by ASHRAE, which serves as a replacement for R22 in such applications as vending machines.

Both formulas perform as refrigerants using smaller volumes than the traditional refrigerants they replace. While both R441A and R443A are flammable, the very small amount of these climate-friendly refrigerants required makes the risk assessment a non-factor.

TEGA blends and distributes both HCR188C/R441A and HCR188C/R443A in Europe.
