Scale inhibitors / Antiscalant

Steam Boilers and Steam Generators are particularly prone to develop scale on their heat transfer systems. This scale, whether calcium, magnesium or silica based, will dramatically reduce thermal transfer and therefore increase energy costs and decrease production. 

Scale is caused by the concentration of hardness (Ca, Mg) ions in the boiler water. If these ions are not dealt with properly they can form deposits and lead to corrosion or even tube failure. To prevent this the incoming water should be treated with a suitable antiscalant / scale inhibitor. 


AQUAGUARD HR series products are liquid boiler water treatment chemicals designed specifically to provide scale, sludge and corrosion control in large or high make up volume steam boilers. AQUAGUARD HR is formulated with ionic dispersants, alkalinity boosters, phosphates and phosphonates. It will effectively tie up calcium and magnesium hardness to form a more easy to disperse sludge. The alkalinity boosters are to ensure the boiler water pH is maintained sufficiently high enough to complex with available hardness. AQUAGUARD HR is not volatile and will remain in the boiler water at all time and will typically not carry over with the steam.
