Compressed air dryer capacity is rated by standard cubic feet per minute (SCFM) capacity, operating pressure, and the dew point range. The right dryer for your system is dependent on a few variables; most industrial applications require common refrigeration dryers, while larger more sophisticated applications that operate within tight tolerances or controlled environments are more suitable for desiccant dryers.
Keep in mind, standard rating is based on 100ᵒF saturated inlet air temperature and 100 PSIG operating pressure. It is important to evaluate the actual performance of the units in their intended operating conditions.
Modern industrial applications require the highest quality air, including, but not limited to applications such as pneumatic automation, electronics, pharmaceutical and food industries. Compressed air that might be sufficiently dry for one application, might not meet the requirements for another.
Although an undersized compressed air dryer will cost less to buy initially, the dryer will be running at full load capacity, resulting in higher operating costs and energy use. Even then, you may have trouble maintaining a constant dew point leading to inconsistencies or variations in the dryness of the compressed air. A correctly sized and installed unit provides long term, trouble free operation.
