Prime Prime Refrigerant
R407F (also called Performax LT) is a blend of HFC refrigerants designed to replace R22, R404A and R507 in low temperature refrigeration applications. Major compressor manufacturers including Bitzer and Copeland endorsed its use in their equipment. Its composition comprises of HFC-32 (30%), HFC-125 (30%) and HFC-134a (40%). 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 R448A (Solstice N40), R449A (Opteon XP40) and R449B (ARM 32b) are HFC/HFO blends that can be used to retrofit current R404A systems. Longer term the use of HFO A2L refrigerants such as R455A (Solstice L40) are likely to replace R404A in new low temperature equipment (not for retrofit).
