Desiccant Dehumidifiers

Desiccant Dehumidifiers

What Are They?

The desiccant dehumidifier is a relatively simple machine offering reliable and efficient removal of moisture for many different processes. It is the most cost-effective method of managing humidity.

How Do They Work?

Consisting of few moving parts, the desiccant wheel is at the heart of the machine and its structure is impregnated with silica gel, to efficiently and reliably remove the moisture.

Dependent on model, advanced control systems on the machines allow for automatic sensing and control of airflows, regeneration heater performance and rotor speeds, all from a simple PLC controller. These can then be linked to either internal or external control and/or plant BMS systems as required, so that performance and process conditions can be correctly met and controlled.

Where Can They Be Used?

  • Pharmaceutical Production
  • Food Industry Processing
  • Cold Stores/Freezer facilities
  • Waterworks
  • General Humidity Management across a range of indoor spaces
  • Across all industries and processes
 What Are They Made From?

The standard materials of construction for these machines are durable stainless steel, approved for high – hygiene use.


Available in a range of airflows from 100 to 25,000m3/hr as STANDARD, the machines fall into a variety of product ranges to meet all likely requirements. Complies with ErP Directive 2015.

  • Sleek, ultra-modern appearance
  • Exceptional build quality
  • Stainless steel construction
  • Low energy consumption
  • Very low-noise operation
  • Easy to install in small spaces
  • Low operating costs
  • Easy to clean and keep clean

Regeneration of the desiccant wheel can be achieved using electricity, steam or gas depending on availability, and as the rotor material is the most efficient currently available in the market, the specific energy input for each kg of moisture removed is the lowest in the industry. Independent tests have shown that our desiccant wheel has an 8.5% better moisture removal capacity than the next best competitor’s product.

The advanced structure of the drying wheel also allows for this advanced moisture removal with a 25% reduction in pressure drop through the dehumidifier unit, allowing for the selection of smaller and more efficient fans and motors.


Optional Equipment?

Most of the desiccant dehumidifiers we are able to provide can be fitted with pre and post cooling or heating modules, heat recovery systems and as condensing units where the location makes it difficult to take away the moisture.
