Hydrax 1972 is a blended formulation of tannins, alkalis and polymers for preventing corrosion and scale in steam, hot water and chilled water systems. Hydrax 1972 is specially formulated for corrosive waters of low hardness containing a high level of silica; also for after sodium exchange softening of a mainly non-alkaline water.Hydrax 1972 is suitable [...]
Hydrax 1971 is an alkalinity builder based on a hydroxide/polyphosphate blend. Hydrax 1971 delays precipitation of hardness salts in feed lines. It may be injected continuously to feed water containing hardness salts without the formation of excessive scale in feed lines.
Hydrax 1970 is a polyphosphate/hydroxide alkali blend and is used for boilers of medium pressure to adjust pH value and to precipitate calcium and magnesium hardness as a phosphate sludge. Hydrax 1970 delays precipitation of hardness salts in feed lines. It may be injected continuously to feed water containing hardness salts without the formation of [...]
Hydrax 1929 is a liquid alkalinity builder based on sodium hydroxide and is especially formulated for use in boiler plant where the feedwater contains insufficient alkalinity. Hydrax 1929 may be safely used in treatment programs incorporating catalysed sodium sulphite oxygen scavenger. This product is a diluted version of Hydrax 1928, so it is more suitable [...]
Hydrax 1928 is a liquid alkalinity builder based on sodium hydroxide and is especially formulated for use in boiler plant where the feed water contains insufficient alkalinity. Hydrax 1928 may be safely used in treatment programs incorporating catalysed sodium sulphite oxygen scavenger.
Hydrax 1927 is a liquid alkalinity builder especially formulated for use in boiler plant where the feed water contains a higher level of dissolved iron than is desirable. It is based on sodium hydroxide and contains a highly effective sequestrant to prevent the formation of boiler scale or deposits containing iron. Hydrax 1927 may be [...]
Hydrax 1926 is based on a blend of sodium polyphosphate and sodium acrylate. It has been formulated to control scale formation in boilers. In open cooling systems, Hydrax 1926 effectively controls both corrosion and scale deposition at low dose rates. Hydrax 1926 delays precipitation of hardness salts in boiler feed lines. It may be injected [...]
Hydrax 1925 is a liquid boiler compound formulated for use in boiler plant where a relatively high hardness make up water has been base-exchange softened - giving a boiler water of naturally high alkalinity.
Hydrax 1923 is a volatile chemical oxygen scavenger which reacts throughout the entire boiler system to control corrosion. Hydrax 1923 does not impart solids to the boiler water and is faster acting than catalysed hydrazine.
Hydrax 1922 is a liquid one-shot boiler water treatment. It combines oxygen scavenger, alkalinity builder and scale inhibitors in one easy to use product.
