Everything you need to know before choosing your device.
Yes. The device plugs into an earthed socket. It stays plugged in continuously, as its instructions specify, and uses very little power: 0.75 W.
The ATE emits very low frequency electromagnetic pulses that act on the polarity of the water in the wall. The moisture is directed back towards the ground and the wall gradually dries out, with no chemical resin injection.
LC15 (Ø 15 m) for small areas, LC30 (Ø 30 m) for a whole house, MAX (Ø 60 m) for large buildings, Pulse (Ø 30 m) for the power of the LC30 with a modern design. The choice also depends on the layout of the building and the source of the damp.
It is the area treated around the device: a Ø 30 m model covers 15 m on each side. It is not a floor area in m². To choose, measure the longest diagonal of the area to be treated.
It starts working as soon as it is plugged in and generates a stable electromagnetic field. It is the solution suited to very damp walls or to buildings that need more intensive treatment.
In France. They are made in the Tarn by SYSELEC, an electronics company. Humidistop has been making them since 2012.
Yes. They are safe for people, animals and plants. ATE devices are EMF-tested in a laboratory (Emitech and Nexio).
You install it yourself, no professional needed: it hangs on the wall like a picture, then plugs into a socket. Allow about ten minutes. The instructions and the installation video guide you step by step: download the instructions for your model.
Low on a damp load-bearing wall, ideally in the centre of the area to be treated, 30 cm to 1 m above the floor. Directly on the wall, never on a lining (plasterboard, insulation). Keep it at least 1.5 m away from electronic devices.
As a guide, allow 18 to 24 months. Progress depends on the materials, the thickness of the walls, ventilation and installation conditions. This timeframe is not a guarantee of complete drying.
Rising damp: water from the ground rising up into the walls. They do not treat penetrating damp, leaks, condensation or flooding, which need a solution suited to their cause.
An ATE uses 0.75 W, or about €15 of electricity a year.
No. The device is silent, vibration-free and maintenance-free. Leave it in place and do not move it once installed.
Strip any impermeable coverings 10 to 20 cm above the damaged areas and ventilate well (mechanical ventilation, air vents). Once the wall is dry, brush off the surface salts and apply a lime plaster.
