Хладагент R404A

R404a refrigerant, refrigerant R404a ,mixed refrigerant,Characteristics&purposes: R404a is a colorless gas under ordinary temperatures, and a colorless&transparent liquid under the pressure of itself, mix by HFC-125, HFC-134a and HFC-143. And it's a long-term substitute for R502, mainly used in refrigerating systems of low & moderate temperature. Uses ammonia or ozone-friendly refrigerants.Dependable Built for industrial use with high quality heavy-duty parts. Designed with a stationary double-walled evaporat and no refrigerant seals to eliminate leaks. Includes important safety features, such as a see-through inspection hatch with safety switch, mechanical load limit switch, emergency stop switch, jog switch, and drive belt guard.Property of chloride: Molecular weight: 97.60 BP, º C: -46.4 Ice point º C: - Critical temperature, º C: 72.1 Critical pressure, Mpa: 3.74 Density of saturated liquid30º C, (g/cm3): 1.045 Specific heat of liquid 30º C, [KJ/(Kgº C)]: 0.38 Specific heat of equipressure steam(Cp), 30 º C and 101.3kPa[KJ/(Kgº C)]: 0.21 ODP: 0 GWP: - Critical density, g/cm3: - Vaporization heat under BP, KJ/Kg: 200.1Packing: recyclable steel cylinder 300kg/400L, 600kg/800L, 700kg/926LPurity%≥ : 99.5 Moisture, PPm≤: 0.001 Acidity, PPm≤: 0.0001 Residue on evaporation, PPm≤: 0.01 Appearance: Colorless, no cloudy Odor: No smell Model NO.: R404aPacking:10.9kg/800kg
