In Trace moisture is inevitably introduced to the refrigeration system during long-term operation. The existence of these trace moisture will lead to a freeze of Capillary or expansion valves. The traces of acid formed by hydrolysis will also corrode metal components, resulting in potential security risks of the system.
At present, the application of environmental friendly refrigerants is vigorously promoted. The application of new refrigerants puts forward higher requirements for desiccants.
According to the Montreal Protocol (Montreal Protocol on Substances that Deplete the Ozone Layer), refrigerants of CFC or HCFC will be phased out due to the destruction of the ozone layer. Countries have began to use HFC refrigerant rather than HCFC refrigerant.
PETROTAT provides molecular sieves of SRC series for various refrigeration system including the HFC. Compared with ordinary desiccants, SRC series products have excellent moisture adsorption capacity, high crushing strength, superior resistance to dry and wet wear and other properties, so it can be operated reliably in either an air conditioning system or automotive air conditioning.
Compatibility is the primary index of SRC molecular sieves. SRC products are widely suitable for types of refrigerant and oil mixture accordingly, such as R-32, R-134a, R-410A, and even R-1234yf
