Prime Prime Refrigerant
Prime Refrigerant R410A, also known as AZ20, is a blend of HFC refrigerants now commonly used for air conditioning applications. R410A was not designed to retrofit existing R22 systems but many manufacturers have used its superior qualities to build products with higher efficiencies. Its composition comprises: HFC-125 (50%), HFC-32 (50%). It is non-toxic and non-flammable meeting the highest A1/A1 classification. HFC's are a type of synthetic greenhouse gas (SGG) having global warming potential. To reduce emissions of these gases globally a HFC phase-down under the Montreal Protocol was agreed in Kigali, Rwanda, in October 2016. Commencing in 2018, the Australian phase down will conclude in 2036 reaching an 85% reduction target. Longer term the use of HFO A2L refrigerants such as R447A (Solstice L41) and R452A (Opteon XL55) could be used to replace R410A in new equipment but not for retrofit. NOTE: GWP calculated on the Australian Government calculator for the Import Levy and Equivalent Price for SGGs and SGG/HCFC blends (Version 1.1, 24 August 2012).
