The wireless OMBRELLO^® wall drying system (wall dehumidification) dries damp walls by means of electro-physical processes. It prevents the absorbency of building walls and transports the moisture that is penetrating from the side or rising from below as the result of capillary effects back into the soil.

OMBRELLO^® is based on electrical and magnetic principles. Due to the emission of electromagnetic waves (long waves) at different frequencies, the frequency range on the building wall is changed so that the tension forces required for the rising capillary damp can no longer occur. Several frequency generators produce the necessary oscillations in the kHz and MHz ranges. The waves are emitted by transmitter coils.

The transmission power of our wall drying system is lower than one-billionth of a watt (1 nanowatt). For this reason OMBRELLO^® does not generate any electrosmog and does not emit any radiation, which could be dangerous for humans, animals or plants. All our devices comply with EMC standards (electromagnetic compatibility). Our technology works with any type of building structure and does not require any prior alterations, as other systems do. Sand, brick, natural stone, hybrid and concrete walls, as well as wood and other natural materials can be dried with OMBRELLO^®.

Technical Information:
OMBRELLO® Functional description (PDF)

The OMBRELLO^® wall drying systems are developed and manufactured in Switzerland. With our many years of experience and close customer contacts we are able to modify our products in response to customer and market requirements and continuously further their development.

OMBRELLO^® is supplied for four different building sizes. This permits the generation of the optimum process range depending on the layout and extent of the area that has suffered damage.

The drying results are documented in detailed measuring logs. Documentation is possible by setting measuring points and

monitoring the drying progress with the aid of two independent, scientifically recognised measurement methods. The resulting measurement logs serve as a basis for the drying guarantee that we give our customers.

After installation of OMBRELLO^®, two subsequent measurements are taken after six and eighteen months. All these services are included in the purchase price. OMBRELLO^® is completely silent and maintenance free, and it only requires a 230-VAC mains power socket.
