Microwaves are produced in an open system. An antenna leads the microwaves into the object. The construction unit is penetrated by the microwaves. The water molecules in the damp construction unit react themselves due to a their dipole character and warming up by molecule friction. Due to this an increased water vapor diffusion takes place.

Advantages:

• Warmth is produced only, where wetness is present
• Dampness escapes within a short time and with minimum expenditure of time
• Dampness escapes within a short time and with minimum expenditure of time
• Biological structures can be killed thermally
