Open Cooling
Treatment4Water supplies water treatment chemicals for open evaporative cooling water systems.
Inhibitors
Treatment4Water provides a comprehensive range of formulated own-label scale and corrosion inhibitors for open evaporative cooling systems. Our proven formulations address issues related to scale formation, general solids fouling, and multi-metal corrosion.
Biocides
Treatment4Water provides a comprehensive range of biocides for open evaporative cooling systems. We stock a wide selection of oxidizing and non-oxidizing biocides covering products to control algae, bacteria, and fungi found commonly in open evaporative cooling systems. Many of our products have a proven efficacy against Legionella.
Inhibitors
Prevention of scaling, fouling, and corrosion in an open cooling system is vital to its safe and efficient operation. Our team of experts are on hand to give valuable selection and application guidance for all our open cooling system inhibitors. In addition, we have a simple but effective one-page selection tool available for those with more experience.
