1.R404A refrigerant is a third-generation HFC non azeotropic mixture refrigerant, composed of precise ratios of R125 (44%), R143a (52%), and R134a (4%),
2.As a classic alternative to R502 and R22, refrigerant R404A has long dominated the field of commercial refrigeration at medium and low temperatures, and is known as the "frozen blood" of the cold chain industry.
3.The core advantage of refrigerant R404A lies in its zero ozone depletion potential (ODP=0), which fully complies with the environmental requirements of the Montreal Protocol. At the same time, its thermal and physical properties are highly matched with R502, achieving a smooth transition for existing equipment.

1.Refrigerant R507 is an environmentally friendly azeotropic mixture refrigerant developed specifically to replace traditional refrigerant R502. It is precisely formulated by mixing R125 (pentafluoroethane) and R143a (trifluoroethane) in a weight ratio of 50%/50%.
2.As a hydrofluorocarbon (HFC) product, refrigerant R507 has an ozone depletion potential (ODP) of 0, which fully meets the environmental requirements of the Montreal Protocol. At the same time, it inherits the excellent refrigeration characteristics of R502 and has become a benchmark alternative solution in the field of medium and low temperature commercial refrigeration, with both safety, reliability, and engineering adaptability.
