Cooling water treatment chemical programs

Protect your cooling systems and optimize performance with Hydrex®
Cooling water treatment chemical programs banner


Cooling systems are critical assets of every industry and typically translate to high operating costs. Scaling, fouling, corrosion and poor legionella control can impact productivity and product quality while causing potential risks to the health and safety of operators. Hydrex® programs for cooling combine chiller chemicals, equipment, digital and services for optimal performance and minimal environmental impact.




To define the optimal treatment and control strategy, the Hydrex chemical program for cooling starts with a  risk assessment to evaluate the system’s configuration and operating conditions, taking into account all parameters and constraints. The objectives of the program are:

corrosive waste picto

To control corrosion rate in order to prevent equipment failure 



Video surveillance picto

To control microbiological activity and cleanliness of the system.




To identify critical process equipment and define specific protection programs.




To prevent technical issues thanks to digital supervision in case of leaks and organic contamination.



seeds picto

To reach maximum sustainability by using the less harmful chemicals and the most environmentally friendly techniques. 

heating picto

To prevent scaling on heat transfer surfaces in order to maximize system performance.




Law picto

To comply with and even anticipate legislation on legionella risk and wastewater discharge standards.




cooling picto

To allow the cooling system to operate at an optimal cycle of concentration in order to generate chemical, energy and water savings.



storage picto

To limit the handling of chemicals and improve safety for the operators thanks to appropriate storage tanks and injectors.
