Frequently asked questions

Everything you need to know before choosing your device.

Power supply

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.

How it works

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.

Model

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.

Coverage

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.

Electromagnetic

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.

Manufacturing

In France. They are made in the Tarn by SYSELEC, an electronics company. Humidistop has been making them since 2012.

Safety

Yes. They are safe for people, animals and plants. ATE devices are EMF-tested in a laboratory (Emitech and Nexio).
