Honeywell R507A refrigerant isR502long-term alternatives have zero ODP and do not contain any substances that destroy the ozone layer. The cooling capacity and efficiency of R507A refrigerant are very close to those of R502, and have excellent heat transfer properties and low toxicity. Therefore, R507A is more suitable for applications in the medium and low temperature refrigeration field than any other known alternative of R502. R507A ratioR404AAchieve lower temperatures, suitable for new commercial refrigeration equipment (supermarket freezers, cold storage, display cabinets, transportation), ice making equipment, transportation refrigeration equipment, marine refrigeration equipment or newer equipment at medium and low temperatures, suitable for all R502 can operate normally. environment. Wherever R502 can be used, R507A can be used instead. Juhua R507A refrigerant is compatible with most materials in the original system, but requires changes to the dryer and other minor parts.
Composition of R507A
Mole percentage: R125 accounts for 41.184%, R143A accounts for 58.816%.
Mass percentage:R125accounting for 50%,R143Aaccounting for 50%.
Refrigeration oil: It is recommended to use polyol ester POE(Polyol Ester) refrigeration oil. When replacing, the lipid oil should contain less than 5% mineral oil, and a variety of lipid oils are usually needed for cleaning.
