ATE LC15, ATE LC30 and ATE MAX – Electromagnetic wall drying devices for rising damp | Quick and easy installation
Discover the ATE LC15, ATE LC30, ATE PULSE and ATE MAX electromagnetic wall drying devices, available in two colours and designed for walls affected by rising damp.
With coverage diameters from 15 to 60 metres, the range offers a choice to suit the layout of your building. Manufactured in France, these devices operate continuously when connected to the electricity supply and require no chemical injections into the walls.
The ATE range is designed to promote progressive wall drying. Drying depends on the building materials, ventilation and installation conditions. A period of 18 to 24 months is indicative and does not guarantee complete drying within a fixed time.
Leaks, water ingress and condensation require solutions suited to their cause. Compare the models or ask our team for advice before choosing your device.
ATE: electromagnetic device that works with electricity. It is generally recommended as the first choice.
ATG: geomagnetic device, completely autonomous and without electricity. Particularly suitable for second homes or public buildings, where a permanent electrical connection is not always possible.
ATE LC15: small areas.
ATE LC30: entire houses.
ATE MAX: large buildings, much more powerful and suitable for all.
ATE Pulse: same power as LC30, with a modern design.
👉 All work with Humidistop® electromagnetic technology, come with a 10-year warranty, and are Made in France.
ATG LC15: small areas.
ATG LC30: entire houses.
ATG MAX: large buildings, more powerful and suitable for all.
👉 All are geomagnetic polarity inverters against wall humidity, with a 10-year warranty and Made in France.
Prioritize the ATE LC15, ATE LC30, and ATE MAX for their efficiency. The ATG geomagnetic device is an alternative if installing the other models is not possible.
Choose a device that covers the entire ground floor for optimal protection.
