DS-T refrigerated drver protects the user's compressed ar system by reducing the moisture content in the compressed air through forcedcooling. The DS-T refrigerated dryer adopts an integrated design of pre cooler, evaporator, and separator, with a high-eficiency doubleshel tube heat exchanger, ensuring that it provides industrial grade drying solutions. The refrigeration system uses low-energy refrigerationcompressors, air-cooled condensers, and environmentaly friendly refrigerants Ri34a and R40A, making the whole machine energy-savingand environmentally friendly
