Intelligent Regen constantly monitors the 
regeneration inlet and outlet temperatures and 
controls them to optimize the energy and dew point 
performance of the dryer.  The control will lower (or 
raise) the regeneration inlet temperature by 5 F. 
(2.4 C) each time the desiccant wheel rotates to 
ensure that adequate, but not excess heat, is used 
to maintain the dryer dew point performance while 
insuring that no excess heat is used and wasted.  
Once the dryer has optimized itself, changes 
cease.  The system insures the best dryer 
performance despite the materials processed, their 
moisture level or any changes in dryer processing 
rate thereby saving energy and improving 
performance. 

 

The Features Menu has a dropdown box 
that displays settings for all activated 
features.
