The life of most refrigeration systems depends on when the refrigerant leaks. The leakage of the refrigerant is caused by the harmful substances produced by the refrigerant and the trace moisture that corroded the pipeline. Molecular sieve has the characteristics of low dew point control, high strength, low wear, and does not destroy the chemical stability of refrigerant. The refrigerant should choose a specific molecular sieve. SNOWPEAK XH-5 molecular sieve is suitable for some chemically very stable refrigerants, XH-7 molecular sieve is suitable for all refrigerants, and XH-9 molecular sieve is specially used for R-401A and B mixture of HFC-152a freezing system desiccant.
The insulating glass desiccant can absorb moisture and residual organic matter at the same time, to keep the glass mooth and transparent even at very low temperature; can reduce the strong internal and external pressure difference due to huge temperature changes, to solve completely the distortion and breakage problem caused by the expansion or contraction of the insulating glass related to ordinary desiccants.
