Prime Prime Refrigerant
Prime Refrigerant R407C is a blend of HFC refrigerants designed to replace R22 in air conditioning applications. Many manufactures designed equipment to suit this refrigerant. Its composition comprises: HFC-32 (23%), HFC-125 (25%), HFC-134a (52%). 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. Low GWP alternatives like Solstice N20 are HFC/HFO blends that could be used to retrofit current systems running on R407C. Longer term the use of HFO A2L refrigerants such as R444B (Solstice L20) will possibly be used in new equipment. 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).
