Operation principles of the TTR desiccant dehumidifiers

The functional principle of the TTR dehumidifiers at a glance

All TTR desiccant dehumidifiers are equipped with reliable silica gel sorption rotors in washable and mechanically high-tensile finish. Due to the chemical stability of silica gel, water vapour or clear water cannot destroy the rotor. Minor soiling such as dust only reduces the dehumidification performance.

Process and regeneration air are channelled in different ways depending on the construction of the Trotec desiccant dehumidifiers:

Legend Operation principles:

  1. Dehumidification sector
  2. Regeneration sector
  3. Purging sector for heat recovery
  4. Process air
  5. Regeneration air
  6. Dry air
  7. Heating
  8. Damp air



One fan for process and regeneration air placed before the rotor. For regeneration a branch current of the dry air is being used.



One fan for both air flows placed before the rotor. With purging sector for heat recovery for the enterin regeneration air.



A separate air flow of process and regeneration air by one fan for each section. With purging sector for heat recovery for entering regeneration air.
