Nu-Calgon 4610-3 - CMS-III Monitor
Nu-Calgon 4610-3 CMS-III Monitor — Conductivity-Based Bleed-Off and Feed Controller
The Nu-Calgon 4610-3 CMS-III Monitor is a precision conductivity control system designed for open recirculating cooling water applications such as cooling towers, evaporative condensers, and closed-loop systems. It helps prevent scale, corrosion, and deposits by continuously monitoring water conductivity and automatically managing bleed-off and chemical feed cycles.
Key Features & Benefits
- Automatic Conductivity Control — Continuously monitors system conductivity and initiates bleed-off when preset limits are exceeded.
- Integrated Feed Pump & Solenoid Valve — Provides precise chemical dosing based on live conductivity readings.
- Compact Modular Design — Easy to install and integrate into existing HVAC or water treatment systems.
- Water and Chemical Savings — Optimizes cycles of concentration to minimize waste and overfeeding.
- Durable Construction — Built for long-term reliability in commercial and industrial environments.
- Versatile Application — Ideal for systems of various sizes, from small to large-scale cooling operations.
