What is Microwave Drying?
First and foremost is it an absolutely 100% effective way of drying building walls, floors and ceilings. It can be used to dry out areas that have been recently flooded, buildings with high humidity, old buildings, residential and commercial.
Walls and floors subjected to standing water tend to get saturated with water. The capillaries fill up with water. This in turn increases humidity rate, foundation walls like this can hold as much as 100 gallons of water per cubic yard.
Left like this foundation walls will never fully dry up and leaving them wet causes other problems such as mold, mildew and unhealthy microclimate.
How does it work?
Microwave drying is based on the absorption of radiation energy. The molecules of water and most resins which are placed in a strong electromagnetic field start vibrating. The vibration causes the molecules to rub against one another, producing heat.
In our devices microwaves permeate into the non-conductive materials, such as building materials (brick, concrete, sheetrock and wood.), and are dampened slightly as they are distributed within these materials.
The water in a wet wall absorbs the microwave energy very efficiently - several thousand times more efficiently than dry material. As a result, a high frequency field, such as a microwave, causes the molecules of water contained in the material to move and rub against one another.
As a result of that rubbing, a large amount of heat is produced, which causes the water contained in the wall to evaporate and disappear from it. That is, the drying of the wall is not done through the heating of the material, but by the direct impact of microwaves on the water contained in the wall structure. Water evaporation is another effect of heating the surrounding material.
The heating process of the material in an electromagnetic field is affected by the factor of dielectric losses of the heated material (the amount of produced heat is proportional), the thermal capacity of the material, the dielectric material constant (the higher the constant, the greater the concentration of the electromagnetic field within it) as well as the thermal conductivity factor. The value of the dielectric constant of water and its dielectric loss factor is high – this is the reason why the moisture evaporates so quickly from walls and floors using this method.
Summary: The microwave generators cause the water contained in the capillaries to be pushed out, towards the wall surface. The entire structure of a wet wall is heated to an optimal temperature so humidity moves towards the external parts of the wall, where it evaporates.
Aside from being the quickest method of drying walls, microwave drying is clean, effective, and non-invasive. It is also the least disruptive method for the occupants of the building, and can optionally sterilize biological elements, such as bacteria, mold, mildew, ants and woodworm.
