Various industrial applications, such as the chemical, pharmaceutical and laboratory equipment, require high-quality compressed air. Desiccant dryers dry compressed air to a standard pressure dew point (PDP) of -40°C. The moisture from the compressed air is captured by an adsorption agent (desiccant). After saturation with moisture, the desiccant enters the regeneration phase, where the moisture is removed from the desiccant. In cold regeneration dryers, a small portion of the dried compressed air is used for this, which flows through the desiccant in the opposite direction during the regeneration phase and removes moisture from it. The service life and efficiency of the dryer depend on the amount of impurities in the incoming compressed air, especially oil residues, which clog the desiccant and thus reduce its adsorption capacity. It is therefore strongly recommended to use a coalescing filter at the dryer inlet before the dryer. It is recommended to install a dust filter at the dryer outlet to capture dust from the desiccant that could leak into the compressed air distribution.
