Automated water treatment for efficient cooling system performance.
A dosing system for chilled water automatically injects treatment chemicals into closed and open cooling circuits to control corrosion, scale formation and microbiological growth. Controlled chemical dosing helps maintain heat transfer efficiency, protects plant equipment and extends system life.
The chilled water treatment system range includes skid-mounted dosing packages with chemical tanks, metering pumps, controllers, sensors and monitoring equipment for corrosion inhibitors, biocides, pH correction and conductivity control.
Dutco Tennant LLC is a premium supplier of water treatment and process solutions across the UAE and GCC, offering reliable dosing systems for commercial buildings, district cooling, industrial utilities and HVAC applications.
