Product categories: PFC

 

Chemical composition: safety levels: A1

 

Packing specification: 9.0 kg recyclable cylinders, disposable cylinder 11.3 kg / 25 lb, recycled cylinder 400 l, 800 l, 926 l, tanks

 

Product detail interface Salt: R508B belongs to the kind of refrigerant, PFC is under cryogenic application [low - 40 ° C to 101 ° C), such as drugs, cold storage, environmental laboratory 13 and R - R - 503 industrial substitute. This product is better than that of R - 23, including to reduce the discharge temperature of compressor, is the optimum system to ensure reliability of the best choice for critical applications. R508B can be applied to new equipment, can also be used to replace the existing systems.

 

Product information: ASHRAE# R - 508 - b replace R - 13, 23 and R - R - 503

 

Application of cryogenic environment, low - 40 ° C to 101 ° C - : drugs cold storage; Environmental laboratory.

 

Advantages of many OEM support; Extend the service life of equipment, exhaust temperature lower than that of R - 23, prolong the service life of the compressor; Improve the refrigeration capacity: 30% percentage points higher than R - 13 refrigeration capacity; Is the best match for R - 503 system of direct replacement refrigerant; Are lower than those of R - 23 the replacement cost of lubricating oil use s ested that POE
