  • Page 8: Section 2 / The Dehumidifier

    ABOUT THE CONDAIR DA35E / DA 35D / DA 35C RANGE OF DEHUMIDIFIERS The CONDAIR DA35E / DA 35D / DA 35C range of dehumidifiers is designed and configured for a wide range of industrial uses. Prominent among these is humidity management in storage facilities and basement areas, in water works and in many kinds of process industry in which stable, well- controlled air conditions are crucial.
  • Page 9 9/128 Configuration priorities The CONDAIR DA35E / DA 35D range is available with four different control configurations – Configuration-A, Configuration-B, Configuration-C and Configuration-D. Control configuration-A is stripped down to a minimum of features and is therefore not equipped with a PLC screen interface.

  • Page 12: How It Works

    HOW IT WORKS Two flows of air The effect of Condair adsorption dehumidifiers basically stems from the action of two flows of air. The drying process (A to E) The incoming moisture-laden flow of air (process air) (A) enters one side of the cabinet and gets filtered by a process air filter (B).
  • Page 13 All models of Condair adsorption dehumidifiers are fitted with filters to remove undesirable particles or other pollutants from the incoming process and regeneration air. Filters of the G4 class are fitted to Condair DA 35E / DA 35D units as standard in order to filter the incoming process air.
  • Page 14 Condair dealer, or Condair. Post-cooling unit Condair DA 35E / DA 35D units can be fitted with post-cooling/heating units to maintain full control of the temperature of the dry air leaving the dehumidifier. Post-cooling/heating units can be retrofitted to DA 35E / DA 35D dehumidifiers with the Configuration-B, Configuration-C and Configuration-D.
  • Page 15 15/128 Heat recovery unit (HR module) Condair adsorption dehumidifiers can be fitted with a heat exchanger to make sure that part of the thermal energy from the regeneration air leaving the unit is extracted, and reused for preheating the incoming regeneration air.
