FILTER DRIERS
Filter driers are essential components in refrigeration systems. Their primary function is to remove moisture from the system using special agents, thus preventing the formation of acids. These filters also protect against contaminants introduced during welding, particles from worn components (such as the compressor or tubing), and any other harmful or abrasive impurities. By doing so, filter driers significantly reduce system breakdowns and extend equipment lifespan.
Molecular sieves differ from other absorbent materials. The first graph below illustrates the superior water absorption capacity of molecular sieves compared to other materials at the same temperature and low relative humidity. The second graph demonstrates that molecular sieves exhibit a significantly smaller decrease in absorption capacity as temperature increases compared to other materials. The third graph highlights the activated alumina's ability to remove acid relative to molecular sieves.
FILTER DRIERS SERIES 45 BAR
Series D/DS: Ideal for CFC and HCFC refrigerants with mineral and alkylbenzene oils, these filter driers are also compatible with HFC refrigerants and blends. The hermetically sealed filter has a beaded structure composed of 80% molecular sieves and 20% activated alumina; it should be installed on the liquid line.
Series DM/DMS: Recommended for HFC refrigerants (including R-22) with POE and PAG oils and additives. The hermetically sealed filter has a beaded structure composed of 100% molecular sieves; it should be installed on the liquid line.
Series DTM/DTMS: Also recommended for HFC refrigerants (including R-22) with POE and PAG oils and additives. The hermetically sealed filter has a solid core structure composed of 100% molecular sieves; it should be installed on the liquid line.
FILTER DRIERS SERIES 140 BAR
Series DC/DCS/DMC/DMCS: Designed for use with CO2 (R-744) in "subcritical" conditions. The hermetically sealed filter has a compact beaded structure, composed of 100% molecular sieves in the DMC, DMCS, DTMC, and DTMCS models, or 80% molecular sieve and 20% activated alumina in the DC and DCS models; for installation on the liquid line.
Series DMC, DMCS, DTMC, and DTMCS: Compatible with POE oils and additives, these hermetically sealed filters have a solid core structure for use on the liquid line. The 90 and 140 versions are designed for use with CO2 (R744) in 90 and 140 bar applications, in the "transcritical" region. The formula for moisture removal is based on 100% molecular sieve for maximum moisture removal and acid prevention.
RECHARGEABLE CARTRIDGE FILTER DRIERS
Rechargeable cartridge filter driers series RCH48 are designed for large industrial and commercial refrigeration systems. They differ from compact filter driers thanks to their large filter surface area and replaceable cartridge.
SILENCER SERIES
The ESSMS series of silencers are used to regulate the vibrations and noise produced by the compressor.
