MicroTron Auto-Monitoring & Dosing System for Cooling Tower Water Treatment

We know that open cooling tower systems offer perfect conditions for proliferation

and dissemination of bacteria such as Legionella.

While it is not possible to completely remove this risk without removal of the system,

it is possible to manage the risk. Taking a ‘Zero Tolerance’ approach to bacteria

control is particularly important for management in high profile, high risk sites. At the

heart of any cooling water risk management plan is the chemical dosage system.

Inter-Chemicals offer full range of dosing control equipment that can be tailored to

suit all applications. Our equipment packages are classified as below:
