Example of cold dryer selection

The rated gas volume of the compressor is 10 m3 / min, and the actual treatment gas volume required under the following conditions:
Ambient temperature: 40 ℃
Intake air temperature: 40 ℃
Intake pressure: 8bar
The actual treatment capacity required is 10 m3 / min / 0.81 / 1 / 1.03 = 12 m3 / min
In order to ensure the pressure dew point, it is necessary to select a cold dryer with a capacity of 12m m3 / min to meet the actual working conditions.
