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
