Hydrex™ Automated Cooling Water Treatment

Cooling systems, which use water for the heat exchange process, are thus subject to corrosion, deposits, fouling and microbiological growth.

Water treatment additives help to prevent such undesirable adverse effects.

To ensure an efficient, cost-effective and environmentally friendly treatment, it is necessary to adapt the chemical dosing continuously to fluctuating make-up and cooling water parameters. That helps to maintain the system's performance, extend its useful service life and prevent health risks to operating personnel and local residents.

With HYDREX AquaVista operators are able to automatically monitor, document and control their cooling water treatment processes. The system also facilitates the remote monitoring of cooling circuits.
