GZ Industrial Supplies Nigeria is the distributor of Harp Brand of Refrigerants in Nigeria. Harp Refrigerant Gas 410A is a zero ozone depletion (ODP) hydrofluorocarbon (HFC) refrigerant blend. Harp® 410A is a binary blend of R32 and R125 (50%/50%) developed as a replacement refrigerant for air conditioning applications previously designed for HCFC R22. Due to both its higher refrigerating capacity and pressure, Harp® 410A should not be used as a retrofit refrigerant in existing R22 equipment.


Harp Refrigerant Gas 410A is used in new residential and commercial air conditioning systems, heat pumps, dehumidifiers and small chillers. Harp® 410A can also be used in some medium temperature refrigeration applications.


Harp Refrigerant Gas 410A is a near-azeotropic HFC refrigerant blend that meets the industry’s needs for many new air conditioning systems. Harp® 410A has an A1 safety rating from ASHRAE (lowest levels of toxicity and flammability), zero ozone depletion potential and a Global Warming Potential (GWP) of 2088. Harp® 410A has both higher pressures and capacity than R22, requiring equipment and components specifically designed to accommodate the resulting higher system pressures and the lower mass flow rates. Typical operating pressures of a Harp® 410A system will be 50% to 60% higher than those in an R22 system at comparable operating conditions. Harp® 410A also has significantly higher volumetric refrigerating capacity than R22 under most operating conditions. This allows OEMs to manufacture equipment of similar capacity and efficiency to R22 in a smaller package.


Due to the zeotropic nature of the Harp Refrigerant Gas 410A blend, it should only be charged as liquid to prevent fractionation (changes in refrigerant composition due to vapour charging). Harp® 410A requires the use of manifold gauge sets, recovery machines, and cylinders specifically designed and rated for its higher pressures.


Due to the significantly higher operating pressures and capacities of Harp Refrigerant Gas 410A, it must never be used as a retrofit in existing R22 systems.


Whenever retrofitting air-conditioning or refrigeration systems, compatibility of system materials is always a concern. Items such as elastomers, hoses, and filter-driers respond differently to different refrigerants and oils. For these reasons, before performing any system repairs, Harp International recommends contacting the OEM for specific recommendations.
