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 |
