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
