This bleed, feed and dual biocide controller offers conductivity and water meter-based control of cooling tower water; control of corrosion/scale inhibitor feed; and has dual biocide timers. Features graphite cConductivity sensor and pH electrode with flow switch manifold mounted on PP panel. Integrated data-logging and file configuration import/export via USB flash disk. As software is updated, it can be uploaded to the unit with the USB disk.
