Anti-Microbial Cooling Towers

Delta’s Anti-Microbial Cooling Towers are designed to minimize the risk of pathogen contamination that leads to infection outbreaks such as Legionnaire’s Disease. The Legionella bacteria thrive in warm water conditions, such as those found in water cooling towers.
Unlike regular cooling towers, Delta’s Anti-Microbial Cooling Towers come with shells made of anti-microbial HDPE resin to inhibit bacterial growth. What’s more, this cooling tower features a unique construction design (steep side-to-side slopes and basin sweeper systems) geared at minimizing the risk of Legionella colonization. Even better, this water cooling tower can withstand strong chemical treatments, which means a much longer lifecycle, reduced costs and downtime.

Introducing Our NEW Anti-Microbial Cooling Tower
According to test results from Special Pathogens Laboratory®, The Legionella Experts®, our tower displays the only Anti-Microbial efficacy against Legionella bacteria out of all the common cooling tower materials.
Tower Shell
• Anti-Microbial HDPE Resin
• Fully Compounded Throughout Resin
• Resists Biofilm Growth
• Withstands Most Aggressive Chemical Treatments
Tower Fill & Drift Eliminator
• Anti-Microbial Compounded PVC or PP
• Impedes Microorganism Growth
• Prevents Fouling Maximizing Performance
• Resists Biofilm Growth
Growth Promotion
• Poor water flow and areas where water is stagnant, common to cooling tower designs with a large flat bottom basin, which will have stagnant water in the corners.
• pH between 5.0 and 8.5, water temperatures between 68°F and 122°
• Sediment that promote growth of commensal microflora
• Microorganisms including algae, flavobacteria, and Pseudomonas, which supply essential nutrients for Legionella growth or harbor the organism
Prevention
• Chemical Water Treatment: Oxidizing Biocides are recommended as the best mode of control. Warning: this type of biocide can be aggressive towards metal surfaces; specifically metal cooling towers.
• System Design & Engineering: No stagnant water, sloped basin, and/or basin sweeper system.
• Maintenance – Competent consistent water treatment and monitoring most important.
• According to the Center for Disease Control and Prevention, about 5,000 cases of Legionnaire’s disease are now reported each year in the United States.
Delta Anti-Microbial Cooling Tower
We begin manufacturing with anti-microbial resin, which is fully compounded into base cooling tower plastic material. Our anti-microbial additives operate on the cellular level to continuously disrupt and prevent uncontrolled growth of the microorganisms and biofilm.
The blue colored cooling towers are a clear sign to the industry that they are anti-microbial; therefore substantially reducing the risk of harmful cooling tower-borne pathogens, such as Legionnaires' Disease.
