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.
Core features and technological advantages
Excellent environmental performance: refrigerant R507 does not contain chlorine atoms and has an ODP value of 0, avoiding damage to the ozone layer from the root; Although the global warming potential (GWP) is 3985, it is still the preferred choice for efficient and environmentally friendly transition stages under strict control of leaks.
Outstanding refrigeration efficiency: The standard boiling point of refrigerant R507 is -46.75 ℃, which is highly matched with the evaporation temperature of R502. The refrigeration capacity per unit volume is increased by 5% -10% compared to R502; The exhaust temperature of the compressor is 7.4 ℃ lower than R502, significantly extending the compressor life and improving the stability of the lubricating oil.
Stable azeotropic characteristics: During the gas-liquid phase transition process of refrigerant R507, the proportion of components remains constant, and there is no need to recalibrate after leakage. The operating performance is always stable, avoiding temperature slip problems of non azeotropic refrigerants.
Strong safety compatibility: ASHRAE safety level is A1, with the characteristics of non flammability, low toxicity, and cleanliness; Compatible with the existing refrigeration system of R502, only requiring the replacement of secondary components such as the dryer, and paired with polyol ester (POE) lubricating oil to achieve optimal operation.
Typical application scenarios
Refrigerant R507 is widely used in:
Commercial cold chain: supermarket display cabinets, food freezing equipment, refrigerated transport vehicles;
Industrial refrigeration: cold storage (-18 ℃~-40 ℃), industrial low-temperature refrigeration units, freeze condensing units;
Special scenarios: Marine refrigeration equipment, biopharmaceutical refrigeration, aquatic product freezer, and rapid freezing workshop;
Repair and replacement: Upgrade and retrofit of refrigerant R502 system and refrigerant replenishment.
Storage and Usage Standards
Packaging form: Refrigerant R507 is packaged in 13.6kg disposable steel cylinders, 25kg/100kg recyclable steel cylinders, and 800kg/1400kg large containers;
Storage requirements: Keep away from fire and heat sources, avoid direct sunlight, store in a cool, ventilated, and dry warehouse, with a temperature not exceeding 40 ℃;
Handling standards: light loading and unloading to prevent damage to steel cylinders and valves, and proper fixation and protection during transportation;
Environmental Reminder: Strictly control leaks and professionally recycle waste refrigerants to meet the emission reduction requirements of the Kigali Amendment.
