Air Drying Units

Our Air/Gas Dryers and Filters are designed for the removal of moisture from process air and gases. This eliminates condensation, freeze-up, and moisture corrosion thus protecting pneumatic instruments and extending the life of pneumatic tools.
The superior reliability of every Air/Gas Dryers and Filters begins with extensive functional testing. Our highly skilled technicians follow a comprehensive testing program to ensure only the most reliable, high performance Air/Gas Dryers and Filters.

2E Dryer

Electric heat reactivated type
Simplified design.
-40°F (-40°C) outlet pressure dew point or better.
Ideal for flow rates from 60 to 3500 SCFM (100 to 6000 m3/h).

Type 2E Dryers consist of two identical pressure chambers filled with desiccant and an external heater for continuous removal of water vapor from compressed air or gases to -40°F (-40°C) dew point or lower. They are capable of processing gas, from 0-100% of the design inlet flow rate, without adjustment. Continuity in the drying process is achieved by switching from one chamber to the other. While one chamber is used for drying, the other is reactivated by a heating and cooling period, with a small dry air purge flow, to assure total regeneration.

3E Dryer

Atmospheric blower type, heat reactivated
Dew-point better than -70°F (-56°C).
Stainless steel desiccant bed screens.
Ideal for flow rates from 200 to over 10,000 SCFM (340 to >17,000 m3/h).
Type 3E Dryers, consisting of two desiccant towers designed to maintain a continuous dry flow, -40°F (-40°C) dew point or lower, are capable of processing gas from 0-100% of the design inlet flow rate without adjustment.

Regeneration of the saturated bed is accomplished by circulating regeneration air by means of a blower through an external heater, then through the desiccant bed, on through a purge exhaust valve, where moisture is ejected to atmosphere. At the end of the heating cycles, a small purge of dry air is utilized to cool the bed down sufficiently before the next switch over. Cooling flow is in the opposite direction to heating, giving the most efficient cool down.
