Mixed Freon refrigerant R508A R508B cryogenic

 Mixed refrigerant R508B Product Name: Mixed refrigerant R508B cryogenic F R503 mixed refrigerant R508B physical properties: molecular weight 95.39 boiling point, ° C -87.4 Critical temperature, ° C 14.0 Critical Pressure, Mpa 3.93 liquid specific heat, 25 ° C, [KJ / (? kg ° C)] 0.31 ozone depleting potential (ODP) 0 Global warming coefficient (GWP) 2.608 mixed refrigerant R508B Packing: R508B disposable refrigerant cylinder 25lb / 11.3kg; recyclable steel cylinder 400L, 800L , 926L; ISO- tank. Mixed refrigerant R508B quality indicators: Purity,% ≥99.8 Moisture, PPm ≤10 acidity, PPm ≤1 evaporation residue, PPm ≤100 Appearance colorless, no cloudy Odor Odorless mixed refrigerant R508B purposes: refrigerants R508B can replace R22. Refrigerant R-508B, alias R508B, trade names SUVA 95, Genetron 508B and so on. R-508B is a part of the refrigerant completely free of ozone-depleting CFC, HCFC substances environmentally friendly refrigerants give currently recognized and recommended by most of the world's major ultra-low temperature refrigerants, R-508B widely used refrigerants in new refrigeration equipment (ultra-low temperature, cryogenic) initial installation and maintenance procedures on the add. Compliance with US environmental organizations EPA, SNAP and UL compliant, American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) security level of A1 category (this is the highest level, harmless to human body). R-508B The main purpose of refrigerant R-508B (SUVA 95) as an ultra-low temperature refrigerant widely used, due to the refrigerant R-508B good overall performance, making it a very effective and safe CFC-13 (R13, R -13, Freon 13, Freon -13), R-503 and HFC-23 (R23, R-23, Freon 23, Freon -23) alternatives, mainly used in environmental chambers / equipment (Thermal Shock Test ), lyophilizer / freeze-drying machine, ultra-low temperature refrigerator or freezer, blood bank refrigerator, biochemical and other cryogenic chamber devices (including research refrigeration, medical refrigeration, etc.), more common for these low-level cascade refrigeration system. R508B refrigerant temperature can be reduced to -80 ℃ or less, is in line with the industry standard R-13, R-503 and R-23 in the long-term alternatives, it is fully adapted to R-503 work environment. Although R-508B is a newly installed refrigerant substitute freon refrigerant R-503 and the most popular choice R13 on ultra-low temperature refrigeration equipment, but due to the refrigerant R-508B and R503, R13 physical and chemical properties, the theoretical cycle characteristics and the compressor oil, etc. are not the same, so for the initial installation of R503 and R13 refrigerant refrigeration equipment Repairs, if need to add or replace refrigerant R503 and still only add R13, usually not directly to R-508B R503 refrigerant to replace , R13 (ie usually shake-style replacement can not be done).
