Drying Compressed Air
Refrigerated Dryers cool compressed air down to a specified pressure
dew point (generally around 2°C or 3°C). As the air cools, condensation
forms which is removed by a separator. This dried air exits the
dryer and travels downstream to the application.
All dryers should be sized to 100% of the rated capacity of the
compressed air system. This capacity is directly related to the
heat load delivered to the dryer from the compressed air flow at
the operating conditions.
Any change in these conditions will affect the heat load, which
in turn affects the dryers performance.
Also, depending on the demand for compressed air at the application,
the capacity of compressed air entering the dryer will fluctuate.
This will further alter the heat load onto the refrigeration system.
It is in these part loaded conditions that the TMS dryer excels,
because it maintains the objective dew point performance when conventional
dryers frequently fail to do so.
