R22 retrofits with no oil or seal changes

CANADA: A new chemical product has been introduced which is said to avoid the need to change the oil, o-rings or gaskets when retrofitting R22 systems to HFCs.

As the pressure mounts on R22, the gas gets more expensive and harder to come by, this new product could save considerable time and expense for companies eager to convert existing plant.

Called Super Change, the chemical has just been released in North America by Cliplight Manufacturing, a Canadian company best known for its range of leak detection equipment, UV dyes and chemical sealants.

The developers claim that Super Change, launched at the end of May, creates a strong compatibility link between mineral/alkylbenzene oils and any HFC refrigerants or HFC retrofit blends. As a result its use eliminates oil change out and replaces the R22 line set conversion flush.

It is also said to rejuvenate o-rings and gaskets, eliminating the need to replace them. Further, Cliplight claims that it boosts oil return and improves heat transfer.

Further information has been promised shortly.
