ORAFON HFC-410a is non ozone depleting, near azeotropic refrigerant blend of hydrofluorocarbons (HFC) R-32 and R-125 developed for use in air conditioning applications. They are used in new residential and light commercial air conditioning systems, heat pumps, dehumidifiers, chillers and other HVAC applications.  Due to the higher refrigerating capacity and pressures of R-410a. It should not be used as a retrofit refrigerant in R-22 equipment.

ORAFON HFC-410a is near azeotropic. To be better to charge it as liquid to prevent fractionation (changes in the designed refrigerant composition) but it can also be charged as gas. Insituations where vapor would normally be charged into a system, a valve should be installed in the charging line to flash liquid from the cylinder into vapor. R-410a requires the use of manifold gauge sets, recovery machines and cylinders specifically designed and rated for its higher pressures.

Polyolester (POE) lubricant must be used with R-410a to ensure complete miscibility between oil and refrigerant. Care must be taken when handling POE lubricants because they are hygroscopic, which means that they can readily absorb moisture from the air. High levels of moisture in the system can lead to oil degradation and system failure.
