Is R11 refrigerant still available?

Is R11 refrigerant still available?

R-11 production was phased out in 1995 but reclaimed R-11 is still available. Older R-11 chillers can continue to be serviced with available R-11 or be retrofitted to R-123 with engineering support from the equipment manufacturer.

What is a characteristic of R 12 refrigerant?

1) Safe properties: Refrigerant R12 is nontoxic, nonflammable, and non-explosive. This makes it highly popular for the domestic as well as the commercial applications. 2) Stability: R12 is highly stable chlorofluorocarbon and it does not disintegrate even under the extreme operating conditions.

What is R11?

Refrigerant R-11 is another refrigerant used commonly in the refrigeration and air conditioning systems. The chemical name of R11 is trichloromonofluoromethane (it is methane series compound) and its chemical formula is CCl3F. R-11 refrigerant is also used as the solvent and the secondary refrigerant.

Is R 11 an HCFC?

CFC Refrigerant: CFC refers to the chemical composition of the refrigerant. Chlorofluorocarbon indicates that the refrigerant is comprised of Chlorine, Fluorine, and Carbon. Common CFC refrigerants are R-11, R-12, R-13, R-113, R-114, and R-115. Common HCFC refrigerants are R-22, R-123, R-124, and R-142b.
