R22

R22

HCFC-22 is a colorless, non-toxic, non-flammable and transparent liquefied gas. Has excellent thermal and chemical properties and does not corrode metals. Used mainly for residential heating and air-conditioning systems.


Uses and Features:

  • R22 is very popular for use in all types of household and commercial refrigeration and air conditioning equipment with reciprocating rotary, scroll and screw compressors.
  • The high refrigeration properties of R22 permit the swe of smaller equipment—a considerable advantage where space is at a premium.
