• Genetron®410A (a near-azeotropic mixture of HFC-32/HFC-125) has been developed by Honeywell to serve as a long-term, non-ozone depleting energy efficient replacement for Genetron®22 (HCFC-22)in a variety of new-equipment applications.
• Genetron®410A has a significantly higher capacity and pressure than Genetron®22 and an intrinsically low toxicity. Because it behaves like an azeotrope, Genetron®410A is easy to service in the field.
• Genetron®410A is patented and has been recognized by underwriters' laboratory as practically non-flammable.
