• HELOT Humidity Control Model Set Up


For locating leaks, various methods are used – such as the acoustic method, forming gas with gas detector, endoscopy, pipe camera, thermography and resistance and dielectric measurement techniques. We use the latest infrared thermographic technology to reliably locate leaks, including those that are hard to reach. Thanks to these elaborate and very accurate measurements, 

our drying techniques can be used optimally and cost-effectively. In addition, a faster and more accurate determination of causes of moisture damage and other negative phenomena is made possible directly on-site within the building. This can only be detected by specific heat radiation from parts of the building.


There are a number of techniques and methods that lead to the path of dryness. Whether a single measurement is sufficient or the combination of several methods is needed - we provide comprehensive advice.

Here are some methods for wall drying at a glance:

  • Wall drying with condensation or adsorption dryers: using dry indoor air or dry air in an air cushion.
  • With fans / fan blowers: stimulating the evaporation of the component surface by air movement.
  • With infrared heating panels: silently drying out with heat.
  • Combination of an adsorption unit and a side channel compressor: Dry air is flooded via a microsystem of Ø 16 mm directly into masonry, additionally drying on the component surface with a cushion of air.


  • We use thermography for locating under-floor heating
  • We are able to remove most of the tiles without causing damage. Alternatively, we offer the CeraVogue inlay process where the drill holes are sealed with ceramic inserts.
  • We use HEPA class H13/DIN EN 1822-1 filter elements as a standard for:
    • under-pressure drying (with HEPA) or for overpressure drying method through drill holes of Ø 50 mm in the screed.
    • Alternatively, to prevent floor damage (e.g. carpet, wood, exposed screed, etc.), drying with side jets on the screed edge strip is used.
    • If neither using holes nor side nozzles near the floor are possible, we offer the option to dry the floor from below through core drillings in the ceiling.


  • – with condensing units: dry air increases the evaporation.
  • – with fans / circulating air blower: convection evaporation from the surface of the component is stimulated by air movement.
  • – with heater fans


  • Air Cleaning (e.g. from mold spores or dust loads) with suction units
  • Odor neutralization by ionization
  • Odor neutralization, sterilization and killing of mold spores by fogging
  • Disinfection of floor insulation
