In flood or pipe burst situation the walls, floors, ceilings etc, become saturated causing the air to become moisture laden as evaporation takes place.

An airmover is designed to deliver a stream of air at or across a surface. They can have variable speed motors and optional sized wheels.

A dehumidifier is a machine that has the capability to extract moisture from the air in a given area.

We have a number of different airmovers and dehumidifiers available for hire and we will advise which is the most suitable according to the circumstances for which it is required.

Airmovers

An airmover is designed to deliver a stream of air at or across a surface. They can have variable speed motors and optional sized wheels. The correct positioning of the airmover is crucial to aid efficient drying. By using a stand, the airflow can be elevated 15° or 20°, A tilt of 45° or 90° can be used to dry walls or ceilings. Using the fan flat to the wet surface will lift moisture from the saturated layer (100%RH) into the general body of air, thus replacing air at the surface with drier air this aids evaporation.

Condensing/Refrigerant Dehumidifiers

This type of dehumidifier lowers the air temperature below the dew point temperature enabling the water vapour to become a liquid. The dehumidifier takes the moist air, draws it across refrigerated causing it to condense. The moisture runs off into a receptacle. The air, which has been "dried" or "processed", is then returned to the room to repeat the process.

Dessicant Dehumidifiers

This type of dehumidifier works on an adsorption condenser basis taking moisture from the air as it is blown through a honeycomb dessicant wheel. During the process air is sucked into the unit via a filter and a radial fan it passes through the rotor where the air is dehumidified. The dry air then passes out of the unit through the dry air outlets. An adsorption dehumidifier works whatever the temperature. At temperatures far below freezing (i.e.-40°C) the air can still be dehumidified. The CTR dehumidifier's regeneration process works continuously. The rotor in the CTR dehumidifier contains high active silica gel and has a very long lifespan.
