Is Puron* A New Alternative Refrigerant?
Puron* is the trademarked name that one equipment manufacturer has given to R-410A. However, developed by a major chemical company who refers to it as Genetron AZ-20**, this is not a proprietary refrigerant and is available for use by the entire HVAC industry. Other manufacturers may adopt similar positioning taglines as they begin to market new R-410A products, so you can expect to see a variety of catchy monikers for R-410A in the coming years. Why Isn’t R-410A More Widely Used Today? The transition to R-410A requires that heat pump and air conditioning systems be redesigned. R-410A is a refrigerant with operating pressures almost 50 percent higher than R-22. Because of this, a redesign of the compressor as well as other components is necessary. Additionally, since R-410A demands special synthetic lubricants for the compressor, there are compatibility issues with the lubricants, cleaners and other fluids used in the manufacturing process. All of these issues must be carefully evaluat
