D‑series refrigerated compressed air dryers are classified into two types based on the cooling method of the refrigeration system: air‑cooled and water‑cooled. When selecting a D‑series refrigerated dryer, it is necessary to specify the maximum flow rate of the compressed air to be treated (Nm³/min), the maximum and minimum inlet pressures (MPa), the maximum inlet temperature (°C), the nominal pressure dew point (°C), and the maximum ambient temperature (°C). Using these parameters, consult the table below to determine the selection factor, then calculate the actual nominal treatment flow rate.
