Meet your challenges head on with our proven solutions.

When microbiological growth, corrosion and deposition occur in industrial cooling water systems, they can lead to flow restrictions, reduced operating efficiency, higher maintenance costs and unscheduled outages. To help maintain the reliability and performance of industrial cooling water systems, Solenis offers state-of-the-art monitoring and control systems and a full line of cooling water treatment chemicals that work at various pH levels and with different water chemistries.

Solenis’ cooling water treatment programs enable industrial operations to improve the reliability and performance of cooling towers, heat exchangers and chill water systems and, as a result, reduce operational costs by mitigating required maintenance, decreasing chemical spend, and conserving water and energy.

Whether your facility has an open recirculating, closed or once-through cooling water system, or whether you are challenged by microbiological growth, corrosion or deposition, we’ve got you covered with one of the broadest and innovative portfolios of cooling water treatments in the industry. This portfolio includes microbiological control treatments for reducing microbial activity and biofilm growth, corrosion control treatments that prevent corrosion from damaging costly equipment, scale control treatments that address the formation of virtually any type of scale, and proprietary monitoring and control systems for controlling biofilm, corrosion and scale.

Notably, Solenis offers performance-based control systems specifically for cooling water treatment programs. These systems use advanced sensor technology to measure actual program performance and provide feedback or feed forward control to maintain desired results.
