Sampling And Testing

A sample of boiler water should be drawn for analysis daily. The sample should always be taken from the same point after blow down, cooled and tested immediately. Follow the Rxsol Hardness Test Kit instructions and fill the Boiler Water Log Form according to result results. It is important that regular testing is carried out to ensure levels of treatment are correct.

Physical Properties :

Appearance        :White powder
Corrosive action  : non
pH 1% solution   : 8,8
Flash point         : none

Application & Dosage

Hardness Control is formulated to form a precipitate with calcium ions which will not adhere to metal surfaces but are in a form suitable for blowdown.

Used for boilers and water softening.

For optimum results dose Hardness Control direct to the boiler via the bypass pot-feeder. The dry powder should be dissolved in hot water (50°C) at a ratio of 1 part powder to twenty parts condensate (e.g. 500 grams/10 litres). Ensure that treatment is fully dissolved before dosing.

This  treatment dosed at 1.49 grams per ton of distilled water provides 1.0 ppm phosphate.
Feed Points: Dose with other BOILER CHEMICAL /  alkaline liquid by diluting withcondensate and feed directly into the system drum (below the water level) using a bypass pot feeder. For low-pressure boilers, It may be dosed to the hotwell or condensate return tank, although this is not the preferred method.
