The TWB Series is the most advanced design in our desiccant dryer offering, it includes a heater and a blower for regeneration of the desiccant bed. This process is known as blower regeneration and is the most energy efficient option available. Instead of using dry compressed air for the purge cycle, a blower pushes hot ambient air across the desiccant bed during regeneration. In order to cool down the desiccant bed, a small percentage of purge air is used at the end of the cycle before the towers switch.

Sizing and Model Selection
To ensure quoted air purity performance is met, a compressed air dryer must be sized correctly for minimum operating pressure, maximum inlet temperature and maximum inlet flow rate using the Product Information Sheet.
