Shandong Renke Launches Automated Water Quality System for Industrial Cooling Towers

What Happened

Shandong Renke Control Technology has introduced an online monitoring platform designed to manage water quality in industrial cooling towers automatically. The system integrates sensor technology with automated chemical dosing and blowdown controls to maintain system health.

The platform continuously tracks parameters such as pH, conductivity, residual chlorine, and turbidity. When levels drift outside of preset ranges, the system autonomously triggers corrective actions, including valve adjustments or chemical injections, eliminating the need for manual operator intervention.

Designed for integration with existing SCADA infrastructure, the system provides real-time data logging and remote management capabilities. This approach aims to replace traditional, infrequent manual testing with a closed-loop system that responds instantly to changes in water chemistry.

The Core Points

Automates chemical dosing and blowdown based on real-time sensor data
Monitors key parameters including pH, conductivity, ORP, and chlorine
Eliminates delays between water chemistry shifts and corrective responses
Integrates with existing industrial SCADA and automation protocols
Supports compliance with ASHRAE Legionella reduction guidelines

Context in 60 Seconds

Industrial facilities are increasingly shifting toward automated water management to mitigate risks related to corrosion, scale, and biological threats like Legionella. By transitioning from periodic manual sampling to continuous digital monitoring, operators can ensure tighter alignment with safety regulations and environmental discharge requirements.

This trend reflects a broader push in industrial sectors, such as data centers and manufacturing, to optimize resource consumption and reduce the operational risks associated with cooling system maintenance. Automated, data-driven oversight helps facilities maintain compliance with frameworks like ASHRAE Guideline 188 while improving overall water use efficiency.

Bottom Line

This system replaces manual cooling tower water testing with real-time, automated controls, helping facilities improve safety and regulatory compliance while reducing operational delays.
