The combined dryer is composed of a refrigerated dryer, a main line filter, a high-efficien cy oil removal filter and a modular adsorption dryer. The compressed air first enters the refrigerated dryer for cooling and dewatering, so that the dew point of the compressed air is reduced to below 10°C, and then enters two sets of precision filters to remove oil, so that the residual oil in the compressed air is reduced to less than 0.01ppm, and finally enters the modular dryer to dry deeply. Because the compressed air has undergone pre-treatment and the temperature is low, after entering the modular adsorption dryer for deep drying, ensure that its dew point temperature is below -40°C. Therefore, the combined dryer is more suitable for the gas use point which with strict requirements on the dew point.
