Demystifying the Dehumidifier

Refrigerant Dehumidifiers

Refrigerant dehumidifiers operate by the air being passed over a cooling coil to drop the temperature below its dew point.

Building Dryers

This term has become familiar for a dehumidifier providing two key functions; first, portability, and second, robustness to withstand typical building site environments.

Building dryers have become standard use within new builds for concrete drying, and water damage leaks on premises under construction. Having said this, they are equally in their element in the restoration industry because of their performance, most typically extract between 40ltrs (lower end) -60 ltrs (high end) per 24 hours.

A strong axle, wide wheels and rotomoulded casing are used to produce machines which can withstand all environments.

Standard Refrigerant Dehumidifiers

A different range of refrigerant units offers the advantage of a more permanent solution, with fixed wall mount models, or fixed bracket ceiling mounted versions, and even a through-the-wall solution.

This opens up a huge variety of different, end-user applications to consider, from warehouse storage to manufacturing processes, through to swimming pool plant rooms.

Extraction rates from 25ltrs- 3000 ltrs/24hrs can be achieved, depending on unit size, and this can either be via a fitted condensate pump or simply drained out via duct work. Some units can still be placed on castors for portability. Other attractive features include sound-proofed compressors resulting in low operating noise, easy access panels and coated internal components to withstand aggressive environments.Refrigerant dehumidifiers don’t operate at low temperatures (below 1 degrees centigrade) however they don’t need any ducting and there is no ‘waste moist air’ generated.

 

Desiccant dehumidifiers

Desiccant dehumidifiers use a silica gel desiccant rotor to remove moisture from the air, and are ideally suited to cold unheated environments such as storage facilities and cold rooms, or to achieve very low humidity in applications such as in the pharmaceutical sector.Desiccant dehumidifiers will operate at much lower temperatures than a refrigerant machine, and will continue to extract moisture from the air even in sub zero conditions, although the air doesn’t hold much moisture under these conditions.  

There is a very large range of unit sizes available, from small portable units through to large capacity semi-permanent installations placed in situ by crane, to provide a solution across all scenarios.  With 2 separate fans handling the regenerated and reactivated air, 40mm rockwool insulation within makes these units quiet to operate. Multiple hose outlets become a very useful feature for Advanced Target Drying commonly demanded by Insurance Companies.
