RS-24 is an easy-to-use Drop-in replacement for R12, There is no need to change the existing lubricant in the system, thereby avoiding a costly retrofit. RS-24 also provides a long term solution to replacing R12 in most applications such as hermetic and semi-hermetic systems, domestic refrigerators, refrigerated transport, cold stores, cellar cooling, dairy chillers, vending machines and including mobile air conditioning.
The properties of RS-24 make it an almost perfect match for R12 with its compatibility for traditional and synthetic lubricants, similar performance, lower discharge temperature, non-flammability and relatively short atmospheric lifetime. Performance relative to R12 is illustrated in Charts 1, 2 and 3 (on subsquent pages - please follow the link at the bottom of this page). It is this combination of properties which makes RS-24 unique as a replacement for R12 on the market today.
RS-24 is also suitable as a replacement for R134a due to its higher capacity which can be particularly beneficial at high ambient temperatures. RS-24 is an excellent replacement for R12 and compatible with R134a automotive air conditioning systems.
RS-24 has been designated an Ashrae number of R426A with a classification of A1, which is low toxicity and nonflammable.
