ORAFON HFC-507a is a mixture of azeotropic HFC refrigerant gases, with zero deterioration of the ozone layer, used in new mid range and low temperature equipment. It is also an indirect replacement (retrofit), in equipment that previously operated with R-502 and its HCFC replacements such as R-408A, DI-44 and HP80. An application such as Cold stores, Refrigerated display cabinets, Ice cream / ice machines, Ice rinks, Cold chambers, Refrigerated transport, Cold drinks dispenser, Freezing tunnels, Fishing boats and Flooded systems.
ORAFON HFC-507a is a long term replacement refrigerant for installations with mid range and low refrigeration temperatures that previously would have used R-502 or R-22. It’s physical, thermodynamic and operational properties are very similar to those of R-502. Discharge temperatures are lower than those of R-502. In some working conditions, the cooling capacity is even higher than that of R-502 but at the same time with a slightly lower coefficient of performance.
ORAFON HFC-507a can be done either as a vapor or a liquid for charging. They compatible only with Polyolester (POE). POE oils absorb moisture quickly when left exposed to the atmosphere. Handle them carefully and avoid prolonged exposure to air.
