EP502
● Characteristics
- CARE 50 is a blend of propane (R290) and ethane (R170) developed to replace R22 and R407C
▶ Primarily for use in commercial air-conditioning and large refrigeration systems that have traditionally used R22.
▶ Operates at similar pressures to R22 and R407C.
▶ Possesses similar volumetric refrigerating effect to R22 and R407C.
▶ Can be used in a R22 or R407C compressors or a specific CARE 50 compressor.
▶ Can be used with R22 or R407C heat exchangers and expansion devices.
▶ Compatible with most common refrigeration materials and lubricants.
▶ Replacement : R-22, R-404a, HFC-407C, HFC-507
▶ Application Range : All kinds of heat pumps, low/ medium temperature commercial refrigeration. Large size chillers in hotels, factories, department stores, large buildings.
▶ Packing : 500gr/CAN, 3Kg/10 Kg/20 Kg/50 Kg Cylinder, Bulk Tank, ISO Tank Container
