    Ateca is a professional party that delivers high-quality products. Products usually last a long time and the maintenance on these installations is zero. In addition, it is a partner who thinks along with the customer in water management and seeks customized solutions to arrange the water management for every owner as efficiently as possible. They also deliver custom made gatekeepers, since every installation is different.
    In addition, they use a high service level!

    We had a massive legionella problem in our bungalowpark. In june 2015 we decided to try the Copper Silver Ionisation (ICA) produced by ATECA. We couldn't be more pleased! No more legionella and no more worries. Our staff in particular is very happy about this purchase.

Break the Vicious Circle

How to deal with drinking water contaminations? There is a fair chance your organisation ends up in a vicious circle. Contamination in water leads to expensive source & site surveys, cleansing with a thermal or chemical treatment. These are followed by a standard protocol such as flushing activities and installation adjustments, but without a guarantee that the contamination problem will be solved.

Often, this leads to unnecessary costs and endless frustrations. Do you recognize this?

With the ICA system you can break this vicious circle and solve the contamination once and for all.

100% safe water
within 1 year
