R507A refrigerant is an environmentally friendly refrigerant widely used in commercial and industrial refrigeration equipment. It is mainly composed of R125 and R143a mixed in a specific ratio. R507A belongs to HFCs (hydrofluorocarbons) refrigerants. It does not contain CFCs and HCFCs that destroy the ozone layer. Therefore, it has been recognized and recommended by most countries in the world. ‌

Physical properties
The physical properties of R507A include:

‌Molecular weight‌: 98.859 g/mol
‌Boiling point‌: -47.1°C (at normal pressure)
‌Critical temperature‌: 70.5°C
‌Critical pressure‌: 3.696 MPa
‌Critical density‌: 0.488 g/cm³
‌Global Warming Potential (GWP)‌: 3985
‌Ozone Depletion Potential (ODP)‌: 0 (does not damage the ozone layer)‌

Application Areas
R507A refrigerant is widely used in the following areas:

‌Commercial Refrigeration‌: Refrigeration systems such as refrigerated display cabinets and supermarket freezers, especially suitable for refrigeration in low temperature environments‌

‌Industrial Refrigeration‌: High-efficiency cooling equipment used in food processing, chemical industry and refrigerated transportation‌

‌Cold Storage System‌: Widely used in low and medium temperature refrigeration facilities such as medium and high temperature cold storage, cold chain logistics, ice cream factories, and wine storage‌

‌Air Conditioning System‌: Replace R22 in large air conditioning and commercial air conditioning systems, especially in environments that require lower temperatures and high efficiency‌

Environmental protection and safety
R507A does not contain chlorine, has no destructive effect on the ozone layer, meets international environmental protection requirements, and is an ideal substitute for R502 and R22. In addition, R507A complies with the standards of the US environmental protection organizations EPA, SNAP and UL, and meets the ASHRAE A1 safety level category, which is harmless to the human body.
