Refrigeration Compressor Filter Drier Selection and Replacement Cycle | Remove Moisture and Acid
Blocked or saturated filter drier causes 31% of slow system contamination and capillary/expansion valve clogging, xiteliduo Refrigeration Compressors provides selection rules. Piston refrigeration compressor system filter drier shall be sized according to refrigerant flow rate; oversized filter will increase pressure drop. Semi-hermetic refrigeration compressor POE oil system uses molecular sieve filter drier for moisture and acid adsorption. Cold storage refrigeration compressor filter drier must be replaced after motor burnout, refrigerant replacement or system opening maintenance. Typical replacement cycle for normal stable cold storage system is 1~2 years; sight glass moisture indicator is the key reference signal. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration filter drier, refrigeration molecular sieve, refrigeration expansion valve clogging, refrigeration system moisture removal, refrigeration compressor manufacturer, cold storage refrigeration system maintenance, refrigeration compressor supplier
