• Closed system corrosion control

Corrosion in your closed water system results when the pitting action of oxygen in a boiler actively destructs the boiler metal. The result is a series of deep holes that self-protect by forming further layers of corrosion – the immediate result is that the problem is masked, but your boiler is left much weaker as a result and by the time the damage is spotted it can be too late to fix. Boiler corrosion can result in increased safety concerns and costly downtime to rectify the issue, but a professional water treatment programme offers a straightforward way to protect your boiler, extend its lifetime and ensure that it remains safe to use.

Boilers and chilled systems – corrosion prevention though chemical analysis

Before beginning a corrosion control programme, Aqualogic carries out a system survey to build up a full picture of your system’s configuration and requirements, and identify weaknesses. Once satisfied that we have understood the design and operation of the circuit,

our technicians collect water samples for on site or laboratory analysis. Checking for inhibitor levels, iron content, conductivity, hardness and total dissolved solids, we report to you detailing how to maintain a healthy system and prevent future damage.

Dosing the closed system to prevent corrosion


Dosing the system with the correct blend and level of chemicals is usually a component of a corrosion control programme. To do this, we safely transport chemicals to your site, which are then added to your closed system through a dosing pot, pressurisation unit or by other means such as injection. These chemicals work to create a less favourable environment for corrosion processes.
