SALIENT FEATURES

» Power on light.
»
On - Off switch
»
Tower pressure guages
»
Highly accurate motorized cam timer.
»
Differential pressure guage for filters.*
»
PLC*
»
Cycle failure indication*
»
Sized to save heat of adsorption - minimizes purge air usage.
»
Limited velocities through tower prevent bed fluidization - stops desiccant dusting.
»
Large desiccant bed - ensures sufficient contact time to produce -40° C Dew point (-80 ° C Dew point with Molecular sieves)
»
Uses bulk desiccant - no special cartridges required.
»
Can be offered for higher pressure and lower dew points also.

* Optional

Fill and drain ports

  • Separate fill and drain ports for ease of desiccant replacement.
  • Heavy duty purge exhaust mufflers for quite operation.
  • Non-lubricated inlet control valves.
  • Purge flow valve for adjusting purge rate.
  • Pressure relief valves on both towers.

Stainless steel support screens and air diffusers

  • Easy removable for cleaning.
  • Filters out gross contaminants protect valves.
  • Prevents channeling.

Structural Steel Frame with complete floor stand

  • Easy installation.
  • Dryer is completely assembled, piped and wired before shipping.
  • Optional factory mounting of pre and after filters.
  • Shipped with full charge of desiccant. Choice between alumina or molecular sieve.
  • Only hookup utilities need to operate.
  • Lifting lugs for easy handling.

Filters

Pre Filter

Every drier should be equipped with pre-filter to protect the desiccant from free water contamination, dust, scales, etc., from compressed air supply. This assures top efficiency and longer desiccant life.

Zero Oil Filter

Oil from the compressor's crank case will be passed on to the line with the compressed air. This will severely effect the life of the desiccant. To enhance, oil particles are removed in this filter upto 1 micron rating.

After filter

This is provided after the drier to remove the desiccant dust carried over to the equipment.
