Our solutions and products for heating water treatment, heating system filling and replenishment

As a trade contractor in the field of heating water treatment, filling and replenishment, you are only “in the clear” if the water quality complies with the relevant standards such as VDI 2035 and EN 1717. To prevent damage and protect warranty claims, modern heating systems must always be filled in accordance with the respective national regulations.

Significantly extending the service life of your heating system through comprehensive servicing and innovative solutions – this is what we are all about. We are also committed to protecting water as a vital resource. We can achieve this together through professional heating water treatment and by helping your customers save costs and energy at the same time.

Magnetite separators, dual filters, degassing and filtration

To enable you to carry out complete heating and cooling water treatment at your customers’ premises, we also have solutions for magnetite removal, mobile degassing and the removal of dirt, solid materials and other deposits in our portfolio. This also extends the service life of heating and cooling systems and fulfils the warranty conditions of the system manufacturers.
