**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.** [CONTACT US TO FIND OUT HOW WE CAN HELP](https://www.veoliawatertechnologies.com/en/contact-web2lead) 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:  **To control corrosion rate in order to prevent equipment failure**  **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.**  **To reach maximum sustainability by using the less harmful chemicals and the most environmentally friendly techniques.**  **To prevent scaling on heat transfer surfaces in order to maximize system performance.**  **To comply with and even anticipate legislation on legionella risk and wastewater discharge standards.**  **To allow the cooling system to operate at an optimal cycle of concentration in order to generate chemical, energy and water savings.**  **To limit the handling of chemicals and improve safety for the operators thanks to appropriate storage tanks and injectors.** ## Features of Hydrex programs for cooling [  ](/services/chemicals-cooling-water-treatment "Cooling water treatment chemicals") [Cooling water treatment chemicals](/services/chemicals-cooling-water-treatment "Cooling water treatment chemicals") Chemical formulations specifically designed for cooling tower water treatment.
