General

One complete system for cooling towers – Conductivity control, Inhibitor & Dual Biocide Dosing with manifold on PVC panel – ready for installation – ready to control. The integrated TRIWA-DIGICHEM® XP2 controller, with data logging, maintains the conductivity of the tower water via its bleed solenoid valve. Corrosion Inhibitors are dosed on bleed, on a cycle or proportional to make-up. Biocide chemicals are dosed according to 10 independent 28-day timer programs. The circulating/condenser pump can be configured to automatically run during and after any biocide dosing program to ensure that the biocide mixes thoroughly.

Specification
