**A critical equipment in every industry, cooling systems represent high operational costs. Scaling and corrosion constitute major issues that can reduce performance and cause system downtime.** **HydrexⓇ 2000 Series of chemical products were specifically formulated for optimal cooling tower operation.** [CONTACT US TO FIND OUT HOW WE CAN HELP](https://www.veoliawatertechnologies.com/en/contact-web2lead) ## Maximize the performance of your cooling water assets In cooling systems, corrosion problems are generally linked to aggressive water or low pH. Mineral fouling is caused by scaling water and/or high skin temperatures (heat exchangers). To cover all these aspects and maximize cooling tower performance, our Hydrex chemical solutions implement specific [cooling water treatment programs](/en/services/cooling-water-treatment-chemical-programs "Cooling water treatment chemical programs ") leveraging the Hydrex 2000 and [Hydrex 7000 Series](/en/services/biocide-chemicals "Biocide chemicals"). Selected by our on-site expert teams according to the specific operating conditions of your cooling systems, they include: - Mineral scale inhibitors including: phosphorus and non-phosphorus based products. - High-performance polymeric dispersants. - Specialty metal corrosion inhibitors for both anodic and cathodic protection throughout the cooling water systems. - Bio dispersants to aid in removing biofouling. - Non-oxidizing and oxidizing biocides. - A wide selection of cooling water system cleaning agents. These formulations are suitable for all types of cooling systems.  ## Features and benefits  **Market approved chemistries to be coupled with [equipment](/en/services/equipment-chemical-water-treatment-solutions "Equipment for chemical water treatment solutions "), [monitoring](/en/services/hydrex-controllers "HydrexⓇ Controllers"), [digital services](/en/services/hubgrade-hydrex-chemical-solutions "Hubgrade for Hydrex® chemical solutions") and on-site support for complete cooling water treatment programs.**  **Can be used with [OSG HydrexⓇ](/en/services/disinfection-salt-electrolysis-osg-hydrex "Disinfection by salt electrolysis OSG HydrexⓇ") to generate fresh biocide in situ from salt hydrolysis only, especially suitable for free pH cooling towers.**  **Compliant, reliable, safe and cost-effective operation of the cooling water systems.**  **Preventive solutions against equipment failure and microbiological growth when used with a biocide.**  **Focus on energy, chemical and water savings.** [  ](/en/services/hydrex-controllers "HydrexⓇ Controllers") [HydrexⓇ Controllers](/en/services/hydrex-controllers "HydrexⓇ Controllers") Hydrex controllers for optimal dosing and monitoring of Hydrex 2000 Series.
