Description
Harp® 407C is a zero ozone depletion (ODP) hydrofluorocarbon (HFC) refrigerant blend. Harp® 407C is a ternary blend of R32, R125 and R134a (23%/25%/52%). It has been formulated to closely match the properties of HCFC R22. It is widely used in new equipment that would have previously used R22 and can with specific modifications be retrofitted into exiting R22 equipment.
Harp® 407C applications include residential and commercial air conditioning systems, direct expansion fluid chillers and some commercial refrigeration systems. Since Harp® 407C has similar properties to R22, it is possible (with modifications) to use it in existing R22 systems. It should not be used in systems with a flooded evaporator.
Made in England.
