R410A Refrigerant, 25 Lb. Cylinder

general description Near azeotropic HFC blend with a zero ODP designed to replace R-22 in many applications such as unitary A/C, chillers, and some refrigeration. It operates at a much higher pressure and capacity than R-22. Equipment, therefore, must be designed to handle R-410A. specifications (Meets AHRI 700-2017 Specifications) Maximum (unless otherwise indicated) Tolerance Difluoromethane (HFC-32), wt % 50.0 (nominal) -1.5%/+ 0.5% Pentafluoroethane (HFC-125), wt % 50.0 (nominal) - 0.5%/+1.5% Air and Other Non-condensable Gases, vol % 1.5 Volatile Impurities, wt % 0.5 High Boiling Residue, vol % 0.01 Moisture (H2O), ppm by wt 10 Acidity, ppm by wt (as HCl) 1.0 Chloride, no visible turbidity (indicates about 3 ppm) Pass Particulates / solids (visually clean to pass) Pass properties Appearance Colorless liquefied gas Odor Faint, ether-like odor Molecular Mass (g/mole of blend) 72.59 Bubble Point at 1 atm - 60.5°F / - 51.4°C Dew Point at 1 atm - 60.5°F / - 51.4°C Flammable Limits (LFL, UFL), vol % (1 atm, 25°C) NA / NA ANSI/ASHRAE Standard 34 Safety Group Classification A1 Ozone Depletion Potential (ODP) (CFC-11 = 1.0) 0 Global Warming Potential (GWP1) (CO2 = 1.0) 1,924 (1) GWP according to IPCC AR5.
