AIR DEHUMIDIFIERS
DFRA SERIES

 
  • The desiccant rotor operates on the silicagel adsorption property and has a long working life.
  • The desiccant wheel rotates in a system with two air flows: The process air passes through the main part of the wheel cross-section and becomes drier because water vapour moves over desiccant material.
    The moisture is removed from the material by heated reactivation air on a smaller area of the wheel cross-section. This process is continuous and uniform as a result of the rotation effect.

MAIN FEATURES

  • Compact and self-contained units made of galvanised steel with enamel finish.
  • Standard models range: From 450 m³/h. up to 24000 m³/h. dry airflow.
  • Water vapour adsorption capacities from 3 kg/h up to 145 kg/h with 20ºC and 60% R.H. process air.
  • Dry air dew point down to -20ºC with a single unit.
  • Reactivation air heating by electric heaters, steam or thermal oil-filled coils or direct fired natural gas.
  • Options on request:
 
  • Higher capacity compact units.
  • Stainless steel frames and fans.
  • High performance air filters
  • Integral pre- or after-cooling coils, for chilled water or DX refrigerant.
  • Integral heater modulation.
