S.sensing® CW-S/D

Automated Chemical Injection Management for Cooling Water Treatment

Measure Automatically. Control Accurately. Optimize Cooling Water Treatment.

S.sensing® CW-S/D is Kurita’s automated chemical injection management system for cooling water treatment. It automatically performs water quality inspections, measures chemical concentrations, and controls chemical injection to maintain stable cooling water treatment performance.

Designed for open cooling tower systems, S.sensing® CW-S/D supports more consistent chemical concentration control by continuously measuring key treatment chemicals and automatically adjusting chemical injection.

Product Overview

Cooling water systems require stable and accurate chemical treatment to help maintain system performance. S.sensing CW-S/D supports this process by automatically measuring chemical concentrations required for cooling water treatment and controlling chemical injection based on the measurement results.

The system uses a colorimetric method with reagent, enabling multiple measurement items to be handled. According to your preference, either slime control agent concentration or scale dispersant concentration can be selected as the measurement item.

Key Benefits

Stable Cooling Water Treatment

By continuously measuring and controlling chemical concentrations, S.sensing® CW-S/D helps maintain consistent cooling water treatment conditions.

Optimized Chemical Consumption

S.sensing® CW-S/D manages chemical consumption to the necessary minimum, supporting chemical consumption reduction.

Cost Reduction Potential

Cost reduction is one of the key outcomes with the application of S.sensing® CW-S/D.
