Boiler Water Treatment Chemicals

Without Treatment

Scale problem without treatment

With Treatment

Clean condition with using Higuard’s chemicals

For Effective Water Treatment

Raw water contains scale-forming ion components such as calcium, magnesium and silica, and corrosion causing ion components such as dissolved oxygen, carbon dioxide etc. These components may precipitate as scale on inner walls of boiler or cause corrosion. This will reduce the thermal efficiency of the boiler and can cause bursting of boiler tubes.

Higuard’s chemicals effectively cope with these problems and thereby ensures safety operation, saving energy and economical operation of your boiler.

Scale Problem in evaporation tube

Scale component crystal of calcium carbonate (Electron microscopic)

Corrosion Problem in condensate line

Condition of dispersion with scale dispersant

DTA Series

(Duplex Twin Alternating)

Iron coated resin

Condition of resin after cleaning

The DTA Softener continuously produces soft water 24 hrs/day, 7 days/week. The intelligent one running, one standby control detects actual quantity of water that passes through the working column and swutches from exhausted column to regenerated column as soon as a predetermined amount of water has passed through regardless of variable flowrates or pauses.

HIGARD Series

MECHMAR

HIGARD 920BC

 

HIGARD 920BC is a stabilized and catalyzed sulfite scavenger for rapid removal of oxygen in feed-water and corrosion protection in boilers. It is non-volatile and is suitable for low and medium boilers operating up to 60 bars.

MECHMAR

HIGARD 931BT

 

HIGARD 931BT is a multi-functional boiler water treatment program for scale and corrosion prevention in industrial boilers using low to medium hardness feed-water. It helps to passivate boiler metal surfaces against corrosion.

MECHMAR

HIGARD 935BT

 

HIGARD 935BT is a polymeric based boiler water treatment for scale prevention in boilers. HIGARD 935BT helps to passivate boiler metal surfaces against corrosion. It is designed to be used in boilers using softened or de-mineralized water and is suitable for boilers operating up to 68 bars (1000 psi).

MECHMAR

HIGARD 945ST

 

HIGARD 945ST is a corrosion inhibitor that was specially designed and formulated to protect steam and condensate system.

It is a blend of volatile neutralizing amines with selected Vapor to Liquid (V/L) ration to be effective in preventing corrosion in the steam and condensate lines. It provides effective neutralizing acidic (carbonic acid) gases in the steam and condensate system. Therefore, it minimizes the potential of boiler tube failure caused by corrosion products.

MECHMAR

HIGARD 957BT

 

HIGARD 957BT is a liquid multi-functional boiler water treatment program for scale and corrosion prevention in industrial boilers using low to medium hardness feed-water. It helps to passivate boiler metal surfaces against corrosion.
