R404A:

(1) product introduction and main use:

By HFC125 refrigerant R404A, HFC - 134 - a and HFC - 143, colorless gas at room temperature, under pressure from its own colorless transparent liquid, is a long-term substitute for r114.

R404A belongs to HFC type non azeotropic environmental protection refrigerants (do not contain ozone-depleting completely CFC, as), recognised by the most countries in the world and recommend the mainstream of the low temperature environmental protection refrigerants, widely used in new refrigeration equipment to add in the process of die erste installation and maintenance. Conform to the environmental protection organization EPA, SNAP and UL standard, conforms to the American society of heating, refrigeration and air conditioning engineers (ASHRAE) A1 security level category (this is the highest level, harmless to human body).

R404A as today's widely used in low temperature refrigerant, often used in cold storage, food refrigeration equipment, refrigeration equipment, Marine industrial cryogenic refrigeration, commercial refrigeration, transportation at low temperature refrigeration equipment, refrigerator cars etc.), refrigeration condensing units, supermarket display cabinets and other refrigeration equipment.
