Hardness Control

HARDNESS CONTROL
BOILER WATER CONDITIONER PREVENT SCALES DUE TO CALCIUM AND
MAGNESIUM SALTS

DESCRIPTION
Hardness Control is a dry phosphates based powder used for the reduction of Hardness in boiler
water systems, and convert these salts into non adherent sludge.

APPLICATIONS
The product is formulated to maintain an optimum phosphate level in the boiler, on these conditions
calcium and magnesium hardness salts cannot be formed, and the precipitant compounds will be
easily blown down.

DIRECTIONS FOR USE
Hardness Control should be dissolved in hot water (50 Deg C), solubility of products is 100gr/litre. Ensure
treatment is fully dissolved.
For optimum results dose Hardness Control direct to the boiler via the by-pass pot feeder installed in the
boiler water feed line. In low pressure boilers Hardness Control may be dosed to the hot well (condensate
return tank).

DOSAGE
Initial dosage for untreated water is 100 gr of Hardness Control per ton of water. Dosage will be increased
or reduced in accordance with result of Hardness and phosphates test. Keep in mind the following
recommended limits:
Hardness value must be zero.
Phosphate value 10/25 ppm for high pressure boiler, for low pressure boiler, 20/40.
