Our range for treatment of internal water in boilers includes corrosion and scale inhibitors, antifoams, condensate conditioners , oxygen scavengers, hardness conditioners and cleaning agents. These products are formulated for all ranges of boiler operating pressures and temperatures and depending on the specific application, can be fed on an intermitent or continuous basis to he boiler fed pump suction, deaerating heater storage compartment, or directly to the boiler shell or drum. All in One These are simple solution which takes care of complete boiler feed water, controls hardness, prevents scale formation and corrosion of metal by controlling pH. It also contains sludge conditioners and oxygen scavengers.

pH Booster / Alkalinity builder
|
To maintain pH in boiler water
|
Oxygen Scavengers These products prevent oxygen corrosion in boilers, economizers, pumps and feed-water lines by chemically removing the last traces of oxygen from feed water. Oxygen scavengers will also reduce certain types of turbine deposits and provide residual effectiveness for protecting boilers during wet standby.

Condensate Conditioners To provide complete protection against corrosion in steam condensate systems, we have developed both filming and neutralizing corrosion inhibitors. When added to boiler feed water, filming corrosion inhibitors volatize with the steam and are carried to all parts of the system where they form a non-wet table, protective film on all metal surfaces. This film prevents dissolved oxygen and / or carbon dioxide corrosion by acting as a water proof barrier between metal and condensate. Neutralizing inhibitors also volatize and travel with the steam. When condensation occurs, they neutralized CO2, elevating the PH of the condensate. In essence, filming inhibitors are used to treat the metal in the system while neutralizing inhibitors treat the water flowing through it.
