Adsorption Dryers:
- The TEGNON RHL Dryer consists of two separate adsorbent chambers. One chamber dries the air or gas while the other is being reactivated - providing a continuous drying operation.
- The wet air or gas enters at the bottom of the left chamber and passes upwards through the adsorbent - where it is dried to dewpoints as low as - 70ºC.
- The dry air passes through the outlet near the top of the left chamber. At the same time, a small amount of the exit air is expanded across a valve between the twin chambers. This purge air flows back through the adsorbent in the right chamber - reactivating it - passing out through the purge exhaust.
- At the end of the cycle the process is automatically reversed with the right chamber doing the drying while the left is being reactivated.
- The TEGNON RHL Dryer unit can be put into operation and will allow flow even if adsorbent beds become inadvertently saturated.

RHH Heat Regenerated Air Dryers:
Heat Regenerated dryers are available from 100 cfm to any capacity required. The heat regenerated dryer uses heated atmospheric air to regenerate the wet lower typical features are:
- High pressure centrifugal purge air blower.
- Water cooled heat exchanger for bed cooling after regeneration.
- Bed cooling in closed cycle to prevent re-adsorption of water vapour.
- P.L.C. cycle control with safety interlocks
- Stainless steel bed supports
- High efficiency particulate after-filter.
- Fully automatic cycle changeover
