CHEMTROL® CT110 Cooling Tower Controller – Smart Water Treatment, Simplified
The CHEMTROL® CT110 is a state-of-the-art cooling tower controller, designed to automate and optimize water treatment in industrial, commercial, and municipal cooling systems. By continuously monitoring key parameters and adjusting chemical dosing in real time, the CT110 enhances efficiency, extends equipment life, and reduces maintenance costs.
Why Choose the CT110?
Cooling towers require proper water treatment to prevent scaling, corrosion, and microbiological growth. The CT110 automates these critical processes, ensuring balanced water chemistry while reducing waste, manual intervention, and unexpected system failures.
Key Features & Benefits
Precision Water Quality Management
🔹ORP & Conductivity Monitoring – Ensures accurate measurement and control of oxidation-reduction potential (ORP) and total dissolved solids (TDS) to maintain optimal water conditions.
🔹Automated Chemical Control – Effectively manages biocide, inhibitor, and dispersant dosing, preventing biofilm buildup, scaling, and corrosion.
🔹Optional pH Control – Provides real-time pH adjustments for enhanced scale and corrosion prevention, featuring the Langelier Saturation Index (LSI) display for advanced monitoring.
