The I.P.E® and I.P.G® devices

What are the differences between the I.P.E® and I.P.G®, and how do I choose the best device for my needs?

The I.P.E® and the I.P.G®  are both designed to treat damp in walls, but each operates in a different way. The I.P.E® is mains-powered, and uses very low audio frequencies to treat damp within your home. These pose no risk to health. The most powerful model can cover a floor area of up to 2,500 m² (26,909.78 sq. ft). In addition, the I.P.E® PRO+ model allows you to monitor changes to moisture levels in your walls using the Rising Damp mobile app. Whatever its size, your home will need only one I.P.E® or I.P.E® PRO+ unit. 

The I.P.G®, meanwhile, uses geomagnetic fields, and needs no external power supply. It can treat an area of up to 700 m², and several devices can be installed in a single home if required.

Which device you choose depends on your specific needs, taking into account the floor area to be treated and the time it takes for your masonry to dry.

If you have any questions, please contact a member of our specialist team.

How and where do I install my device?

The I.P.E® requires a continuous power supply, so it must be positioned close to an electrical socket. It also needs to be installed on a load-bearing wall, and should be accessible for monitoring purposes, particularly in the case of the I.P.E® Pro+ with its dedicated mobile app.

The I.P.E® Pro+ must be mounted on a damp, load-bearing wall, or the app will not function. The device will dry your walls as intended, but you won’t be able to monitor progress. 

The I.P.G® is supplied with a wall bracket, and must be fixed to a wall (load-bearing or non-load-bearing) at a height of between 1.7 and 2 metres. The I.P.G. needs no power supply as it draws its energy from the Earth’s geomagnetic fields.

For more information on installation, please see our explanatory videos, or download the product file for your chosen device.

What guarantees are there on your products?

We are confident that our devices are both reliable and durable. Each one comes with a 30-year manufacturer’s guarantee. There is also a 2-year guarantee for the mains adaptor supplied with the I.P.E® and I.P.E® Pro+. Your satisfaction is our priority.
