2L Refrigerant Flammability Fire Protection Engineering at University of Maryland Research (published 2014 Purdue Refrigeration) The hot plate ignition temperatures of R-32 and R-410A were 764 and 790 °C. For POE and mineral oil these were 645 and 764 °C, while their closed cup ignition temperatures were 445 and 338 °C. Ignition temperatures of refrigerant/oil mixtures were essentially the same as for the oil.
