IWTM – industry leading specialists in chemical-free water treatment solutions.

Founded in 1992, IWTM have been working with chemical free water treatment using electrochemistry for over 30 years and have offices in Norway, UK, Finland, Sweden, Canada, USA and a worldwide presence in the Marine sector.

Class-leading water treatment to VDI 2035 standards; cleaning established systems or protecting new.

The first three years of our presence in the UK we witnessed an increased use of chemical-free water treatment for domestic, commercial and large industrial heating and cooling applications. During this time we have had particular success with large volume networks and systems that operate on low and intermittent flow. This has been recognised both by the many blue-chip clients who have installed our systems and by respected professional bodies. CIBSE confirm within CP1 Heat Networks Code of Practice and The Heat Networks Design Guide that our methods are the best suited for systems of this type.

Using sacrificial magnesium anodes to extract oxygen, acid and aggressive salts from the water, the IWTM Protector addresses both the symptoms and root cause of corrosion within recirculation heating and cooling systems. Our proven technology engineers optimum environments for these systems, one where corrosion can't occur and bacteria can't survive.

Serving both domestic and commercial markets, our comprehensive range of products combine to ensure the operational reliability and efficiency of your systems, protecting and extending the operational life of expensive assets, increasing energy efficiency whilst reducing running costs and avoiding unnecessary maintenance costs and system downtime.

Our in-house team welcome enquiries relating to system function, specification and design for new build, conversion and renovation projects.

Suitable for any size or type of closed loop heating or cooling system such as homes, apartments, advanced systems incorporating underfloor heating, heat pumps, commercial, hotel and leisure, district heating or even power stations, IWTM engineering ensures greater energy efficiency, sustained trouble-free operation and essential compliance with warranty conditions.
