Product Short Description: Liquid 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. Product 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.
