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.
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.
A harmful lung infection caused by the bacteria Legionella. This bacteria grows best in warm water conditions where it is spread to humans when water vapor or mist containing the bacteria is inhaled. Cooling towers have an ideal environment for this growth. Although the public concern about Legionnaire’s Disease was paramount during the outbreaks of the mid-1970s, there have been many recent occurrences since then, including over a dozen cases in the U.S., as well as several in Europe and Australia. According to the CDC, in many of these cases Legionella is incubated and spread through water systems, including the cooling towers that are essential items in commercial building HVAC systems and industrial process cooling.
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.
The bacteria tested were Legionella Pneumophila Serogroup 1. The base materials tested were Delta Compounded HDPE, FRP, and Stainless Steel and the numbers reflect bacterial count after 24 hour incubation.

Stagnant Water is a breeding ground for microorganisms which reproduces Legionella. Our design prevents stagnant water.
Delta Cooling Towers contain one piece, shell or casing, eliminating issues with seams, welds, and patches. Because they are rust and corrosion proof, Delta’s Cooling Tower Systems endure longer lifecycles.
Our overall maintenance is minimal and the tower shell does not require preventive maintenance which lowers cost and expensive downtime. The benefits are extraordinary!
Water chemistries and engineered plastic cooling towers combined translate into an extremely effective solution to water conservation as well as cost savings.
The noise pollution of commercial HVAC equipment has become an increasingly unwanted problem for communities. Delta Cooling Towers are unrivaled among other manufacturers in providing solutions.
The term “Made in the USA” speaks of quality, excellent craftsmanship, and a superior product. Delta ranks as the technology leader among cooling towers manufacturers in USA!
