EP22
● Characteristics
- CARE 45 is pure propene (propylene) (R1270)
▶ Primarily for use in commercial air-conditioning and large refrigeration systems that have traditionally used R22.
▶ Operates at slightly higher pressures than R22 but similar to R404A and possesses similar volumetric refrigerating effect to R22 and R404A.
▶ Can be used in R22 or R404A compressor or a specific CARE 45 compressor. Can be used with R502, R22, R404A and 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 : Commercial air-conditioner, large size commercial fridges. Large size chiller in hotels, department stores, large buildings.
▶ Packing : 500gr/CAN, 3Kg/10 Kg/20 Kg/50 Kg Cylinder, Bulk Tank, ISO Tank Container
