Refrigerant dehumidifiers

Unlike most suppliers, the Dantherm Group product ranges include both refrigerant AND desiccant drying equipment. With products that span both technologies, we can offer impartial advice that provides a solution specifically suited for your application.

The process of dehumidification involves moisture-laden air (return air) being drawn into a dehumidifier where the air passes across a refrigerated coil. The air is rapidly cooled below its dew point, condensing the water vapour and recovering its latent heat energy for re-use. The cooled air is then passed across the condenser where it is reheated and (supply air) returned to the served area at the required lower humidity.

Advantages:

  • Low energy consumption
  • Minimal maintenance required
  • High specific moisture extraction (kg/kWh)
  • Easy installation
  • Small diameter condensate drain

Disadvantages:

  • Low performance in cold conditions below 3°C
  • Smaller dehumidifiers less suitable for ducting

Where used:

Generally, in recirculation applications where the humidity requirement is above 40% RH.

  • Preservation during storage
  • Data centres
  • Substations and switch gear rooms
  • Clothes drying
  • Food drying
  • Swimming pools

Where not used:

  • Single pass (total loss) ventilations systems
  • Below 40% RH
  • Below 3°C
  • Explosive environments
