Chemical Water Treatment - Services

Cooling Towers/ Evaporative Condensers

Integra‚Äôs team of specially trained technicians provides services to minimise risk of legionella and microbial growth, minimise scale formation, corrosion and fouling. Our staff work closely with the onsite employees to ensure risks are minimised whilst operating the assets as effective and efficiently as possible. 

It is extremely important that the right chemical program is selected to effectively treat a cooling water system. The risks can be significant when dealing with control of legionella and bacteria which can proliferate when not managed correctly.

Integra provide electronic service reports at each service, capable of being emailed whilst leaving hard copy of reports onsite to maintain council compliant log books.

Closed loop condenser 

Closed loop condenser circuits are monitored and serviced quarterly.

Heating and chilled water systems

Closed recirculating water systems are found in a variety of commercial and industrial facilities. These systems can be used for either heating (hot water loop) or cooling (chilled water loop) or closed condenser water loops. 

The most common problems associated with closed loop systems are corrosion, fouling as a result of corrosion by-products, build-up over time of dirt from the makeup water and potentially microbial growth. Scaling and or deposition are unlikely as make up water rates are low and the absence of evaporation limits hardness salts and other impurities to the level of the makeup water.

The build-up of dirt in the system will lead to erosion and under-deposit corrosion, while bacteria growth can lead to loss of corrosion inhibitor, pH excursions or loss of heat transfer as a result of slime growth.

Steam Generating Boilers

Corrosion control in steam boilers is achieved by efficient chemical removal of dissolved oxygen from feed water and boiler water. A catalysed solution of sodium sulphite or a blend of natural tannins is used. This reacts almost instantaneously with dissolved oxygen even at low temperatures. This rapid reaction provides greater protection to the boiler and pre-boiler section, especially where mechanical deaeration is not complete.
