Dosing agent

JH 1, combination of alkali phosphates and a non-volatile oxygen binding agent. Suitable for food processing industry.

Field of application: Mainly hot water heating systems with a heating capacity of over 100 kW (german VDI 2035).

Effect: Alkalization (increase of pH-value), oxygen binding in boiler feed water and residual hardness precipitation.

Preparation: As 10% solution, with softened water.

Approx. 5 – 10 mg/l phosphate (PO₄³-), observe boiler guidelines.
Approx. 5 – 20 mg/l excess sulphite, observe boiler guidelines (sample water cooler required).

Scope of delivery:

Available in the container size 10 kg.


For aluminium/silicon components, the pH value must not exceed 8.5!
