Supply R404A refrigerant

Refrigerant R 404a (mixed refrigerant, environmentally friendly refrigerant) is mainly used in some cryogenic refrigeration systems, it is long-term alternative refrigerant R502. Product Name: Mixed refrigerant R404A Physical properties: molecular weight 97.60 boiling point, ℃ -46.4 Freezing point ℃ - critical temperature, ℃ 72.1 Critical pressure, Mpa 3.74 saturated liquid density 30 ℃, (g / cm3) 1.045 liquid heat 30 ℃, [ KJ / (Kg · ℃)] 0.38 isobaric vapor specific heat (Cp), 30 ℃ and 101.3kPa [KJ / (Kg · ℃)] 0.21 ozone depleting potential (ODP) 0 Global warming coefficient (GWP) - critical density, g / cm3 - the boiling point of evaporation potential, KJ / Kg 200.1 Packing: 10.9KG / bottle quality indicators: Purity% ≥ 99.5 Moisture, PPm≤ 0.001 acidity, PPm≤ 0.0001 evaporation residue, PPm≤ 0.01 look no color, not muddy odor Odorless Products: R-404A refrigerant, alias R404A. Since R-404A HFC type zeotropic belong refrigerants (completely free of ozone-depleting CFC, HCFC), to obtain recognition of the vast majority of countries in the world at present and recommend the mainstream cryogenic refrigerants, widely used in new refrigeration equipment The initial installation and maintenance process to add. Compliance with US environmental organizations EPA, SNAP and UL standards, in line with American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) the A1 security rating category (this is the highest level, harmless to human body). Main purpose: R-404A refrigerant as a low temperature in widespread use today, often used in cold storage, food refrigeration equipment, marine refrigeration equipment, industrial cryogenic refrigeration, commercial cryogenic refrigeration, transport refrigeration equipment (refrigerated trucks, etc.), refrigeration condensing units supermarket display display cabinets and other refrigeration equipment. R404A refrigerant freon R22 and R502 is an alternative to the most common industry standard refrigerant (usually freezing systems) newly installed refrigeration equipment, R404A closest to the operation of R-502, which applies to all R-502 can operate normally environment, R404A recognition and use of most of the world's refrigeration equipment manufacturers. However, due to R404A and R502 and R22 physical and chemical properties, theoretical cycle performance and compressor oil, etc. are not the same, so for the initial installation of R502 and R22 refrigerants equipment Repairs, if you need to add or replace the refrigerant, still You can only add R502 and R22, normally can not be replaced directly R404A R502, R22 (ie generally not be shake-style replacement).
