Description

Hardness Control is a Liquid product used for the reduction of hardness in boilers and to adjust hardness and phosphate. Hardness Control is highly soluble in water and It will precipitate calcium hardness as a non-adherent sludge.

USEFULL  to adjust hardness and phosphate .



A precipitant designed to elimate scale deposits and lower the hardness of water in boilers with working pressure up to 60 bars.



It is used in conjunction with alkaline liquid to prevent calcium scale deposits. Both products are used in our standard boiler water treatment programs for low-pressure boiler systems (0-32 bar) and medium-pressure steam propulsion vessels (32-60 bar).  Reduction of Hardness in boiler water system, and convert these salts in non adherent to avoid scale formation. It will precipitate calcium hardness chemically.

Description

Hardness Control is aLiquid product used for the reduction of hardness in boilers. Hardness Control is highly soluble in water and It will precipitate calcium hardness as a non-adherent sludge.

Application and use

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.

Dosing method

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.

Select row on righthand side for applicable pressure range. Compare test result with comment in table and dose stated amount of product per ton boiler water volume.

These are recommended values based on experience and are in no way intended to replace the boiler manufacturer’s specifications or company regulations.

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.

Benefit and Features

  • Highly active phosphate based compound, economical in use.
  • Easily dissolved in water for dosing.
  • Scale problems due to calcium are eliminated.
  • Maintains sludge in a non-adherent state for ease of blow down.
  • Simple test to determine level of treatment.
  • Can be used for boilers of all pressures.
  • Rxsol Hardness Control does not influence the alkalinity in the system.
