R508B Refrigerant Gas|Cryogenic refrigerant| Titanium cylinder 8kg

R508B ultra-low temperature refrigerant is an environmentally friendly azeotropic refrigerant that does not contain ozone-depleting CFC and HCFC substances. It has been recognized and recommended by most countries in the world. Widely used for initial installation on new refrigeration equipment (ultra-low temperature, cryogenic) and addition during maintenance. As a widely used ultra-low temperature refrigerant, R508B is a substitute for R13, R503 and R23, mainly used in environmental test chambers/equipment (cold and thermal shock testers), freeze dryers/freeze dryers, ultra-low temperature refrigerators or freezers, blood bank refrigerators In cryogenic equipment such as biochemical test chambers (including scientific research refrigeration, medical refrigeration, etc.), the low temperature grades used for these cascade refrigeration systems are more common. R508B refrigeration temperature can be reduced to -80℃ or even lower, it is a long-term replacement for R13, R503 and R23 in line with industrial standards, it is fully adapted to the working environment of R503.

R508B refrigerant is a PFC refrigerant and is suitable for ultra-low temperature applications [as low as -40°F to -150°F (-40°C to -101°C)], such as R-13 and R-13 in pharmaceutical cold storage, environmental laboratories Industrial grade replacement for R503. This product is superior to R23, including reducing compressor discharge temperature, and is the best choice for critical applications ensuring optimum system reliability. The R508B can be applied to new equipment or used to replace existing systems. Applications Ultra-low temperature environments [as low as -40°F to -150°F (-40°C to -101°C)]: pharmaceutical cold storage; environmental laboratory. Supported by many OEMs; prolong equipment life: lower discharge temperature than R23, prolong compressor life; improve cooling capacity: 30% higher cooling capacity than R13; it is the best matching direct replacement refrigerant for R503 system.

Although R508B refrigerant is the most common choice to replace Freon R503 and R13 on newly installed ultra-low temperature refrigeration equipment, because R508B and R503, R13 have different physical and chemical properties, theoretical cycle performance and compressor oil, etc., so for the initial installation of R503 After-sales maintenance of refrigeration equipment with R13 refrigerant, if you need to add or replace the refrigerant, you can still only add R503 and R13, usually you cannot directly replace R503 and R13 with R508B (that is to say, it is usually not possible to carry out exchange-type replacement. ).

Composition of R508B refrigerant

Molar percentage: R23 accounts for 62.6751%, R116 accounts for 37.3249%

Mass percentage: R23 accounts for 46%, R116 accounts for 54%

R508B supporting refrigeration oil

Emkarate RL32H, Solest LT-32, etc.; which refrigerating oil is finally used in different equipment and different application places, should follow the recommendations of refrigeration compressor and refrigeration (air conditioning) equipment manufacturers, or according to the specific use of refrigeration compressors and refrigeration equipment. According to the situation, it is determined to use the refrigerator lubricating oil with the same design requirements, that is, the equivalent refrigerator oil is selected.
