The reference formula for the selection of the processing capacity of the refrigerated dryer:
• Processing capacity of cold dryer at rated ambient temperature=air compressor discharge/C1 * C2 * C3 * C4
C1: ambient temperature correction coefficient C2: intake temperature correction coefficient ＜ 3: working pressure correction coefficient ＜ 4: pressure dew point correction coefficient

Selection of adsorption dryer:
• The processing capacity of the rated suction dryer is determined according to the GB10893-89 standard under the condition that the inlet pressure is 7bar and the inlet saturated air temperature is 38< br/> When the inlet air pressure does not meet this working condition, it shall be corrected as follows:
