INNOVATIVE DESIGNS:
Three basic designs are highly configurable into a wide array of variants optimized for the customer’s application

ENERGY OPTIMIZED SOLUTIONS:
Dryer technologies ranging from demand controlled zero purge to heat of compression and combination dryer designs

iDRY® Heat Reactivated Desiccant Air Dryer

Adsorption Phase
Saturated compressed air enters the dryer through a required coalescing prefilter (not pictured) and flows through the open inlet valve [1]. Air flows upward through the tower where the desiccant extracts and retains water vapor [2], thereby lowering the dew point, before exiting the top of the tower. The dry air passes through the outlet check valve [3] and passes through the particulate post-filter (not pictured) before exiting the dryer to the air distribution system [4]. A small amount of dry air is diverted from the outlet flow of the drying tower to be used in regenerating the other tower. This diverted air is controlled by the adjustable purge valve [5].

Regeneration Phase
The purge air flows through an in-line heater [6] thereby reducing the amount of purge required to complete the regneration process. The purge air flows into the regenerating tower at near atmospheric pressure. This heated, dry air flows downward through the tower [7], absorbing water from the moisture laden desiccant, before exiting near the bottom of the tower. This moist purge air passes through the purge exhaust valve and is vented to open atmosphere [8] through the muffler. After a set amount of time, the heater turns off [9] and the purge air is cooling the heater and desiccant bed [10]. After a pre-established amount of time the exhaust valve closes [11], re-pressurizes the vessel. The air flow through the dryer will then reverse, turning the drying tower into the regenerating tower.
