Desiccant Dehumidifiers

What makes our units different?


What is the best way to ensure maximum drying for a Rentalized Desiccant Dehumidifier?


  1. Order only DH Models with 400mm thick desiccant wheels
  2. Order DH models with standard 200mm thick desiccant wheels
  3. Order all DH models with a 100mm desiccant wheel thickness
  4. The thickness of the desiccant wheel does not affect the drying ability

For desiccant wheel manufacturers there are typically 2 depths (or thicknesses) of wheel material available.  The first size, 200mm is less thick.  It is typically used for commercial applications.  The second size, 400mm is the thicker option.  By utilizing a thicker or deeper wheel we can get better drying performance.  This wheel is typically used for industrial applications.  With the deeper wheel, the process air takes longer to pass through the desiccant and therefore, dryer air is produced at the outlet. 

At Smart Family, we only use 400mm thick wheels for our RDDH-EH series.  This guarantees the very best drying performance for our Rentalized dehumidifiers.  This, in turn, provides United Rentals, the best DH RENTAL performance in the business.

In addition, we use only NON-Proprietary controls (simple to use).  We have also upgraded all blowers to high static models so that you can provide high static pressure (force behind the air) to your customers.
