Refrigerant Major Applications and Notes
R404A HFC No P.O.E Liquid only
For new medium & low temperature applications.
(Can replace R502 but requires careful retro-t
procedure)
R507 HFC No P.O.E
Liquid or
Vapour
For new medium & low temperature applications.
(Can replace R502 but requires careful retro-t
procedure)
Note: The only difference between R404A & R507 is R404A has 4% of R134A added (for patent reasons)
R408A HCFC Yes
Mineral/P.O.E
Alkylbenzene
Liquid only
Interim replacement for R502. (Availability - large
scale reductions from 2005)
R502 CFC Yes
Mineral or
Alkylbenzene
Liquid or
Vapour
No longer manufactured. (High ozone depleting fac-
tor) Used on freezers & med ium temp applications
- see R408A, R404A, R507.
R22 HCFC Yes
Mineral or
Alkylbenzene
Liquid or
Vapour
For air conditioning, medium & occasionally low
temperature applications. (Availability - large scale
reductions from 2005)
R407C HFC No P.O.E Liquid only
For new larger to medium air conditioning & some
smaller applications. (Can replace R22, careful
retro-t prodecure required)
R410A HFC No P.O.E Liquid only
For new smaller (residential type) air conditioning
applications. (Requires high pressure components
& service tools)
R134A HFC No P.O.E
Liquid or
Vapour
For new medium temp & domestic freezers, small
commercial jobs. (Can replace R12 & R500 - but
requires careful retro-t procedure)
SP34E HFC No

Alkylbenzene
Liquid only
Interim replacement for R11 - requires careful retro-
t procedure. (Availability - large scale reductions
from 2005)
R11 CFC Yes
Mineral or
Alkylbenzene
Liquid only
No longer manufactured. (High ozone depleting
factor) Used on centrifugal chiller applications - see
R123.
