Our product range for bivalent heating water treatment
Our product range extends from the initial filling and replenishment of make-up water to magnetic flux filters and corrosion monitoring.
With UWS treatment units, they treat the heating water bivalently using the bypass process; the units soften, desalinate and filter at the same time.
Fully demineralized water with mixed bed resin Vadion pH-Control
In order to meet the values recommended in VDI 2035 (hardness of 0.3 °dH, conductivity ≤ 100 μS/cm and a pH value of 8.2 – 10.0 in stainless steel systems or 8.2 – 9.0 for aluminum components), we have developed our mixed bed resin Vadion pH-Control has been developed. In addition to desalinating the water to < 100 µS/ cm, it also ensures that the pH value of the filling water is within the required range. The application range is in a temperature range from 3 °C to 80 °C. This also makes it possible to remove existing residual hardness and dissolved salts in the heating water of a heating system during operation (bypass process)
Heating water treatment
Why
Heating water treatment?
Stone formation, corrosion and magnetite are frequent causes of damage in the event of problems with the heating system. The VDI 2035 specifies guide values for the heating water for these reasons. These form the basis of many warranty conditions – which planners, installers and operators should always keep in mind. If the specified guidelines are not adhered to, there is a risk of:
- Refusal of commissioning by the manufacturer
- Refusal of the warranty claim in the event of damage and
- Performance and efficiency losses
- Medium/long-term damage to the system.
A word about the most important standards
Core of the VDI 2035 is the prevention of stone formation and corrosion damage caused by water. EN 1717 regulates the protection of drinking water against non-drinking water and according to EN 14336, heating systems must be flushed before commissioning.
Other standards apply in other European countries. In Austria, for example, it is ÖNORM H 5195-1, in Switzerland SWKI BT 102-1, but many countries now base their standards on VDI 2035.
