HDD Series Desiccant Adsorption Type Compressed Air Dryer

HDD Series Desiccant Adsorption Type Compressed Air Dryer


The HDD series of heatless desiccant compressed air dryers is a great solution for applications that require low compressed air dew points along with high reliability and minimal maintenance. This compact design allows for minus 40°C performance with -70°C options. The HDD modular aluminium series dryers are a simple solution for any low flow application.

A portion of dried low dew point air from the online drying tower is reintroduced in a reverse direction into the “wet” tower to desorb the drying media. This low pressure air flow carries the moisture in vapour form to the atmosphere via a high performance silencer muffler.

The HDD dryer is fitted with a versatile timer control that allows for drying time adjustments. It also has a three position switch system that places the dryer into one of three modes, these are;

  • Timer control only
  • Timer with dew point display
  • Integrated timer and dew point control

These dryers are complete with inlet and outlet high quality filters, dew point probe (control) is an option extra.


  • A three tower design complete with an activated carbon tower is available.
