A line of towers from Delta Cooling Towers is constructed from antimicrobial resin, which is fully compounded into the base cooling tower material. The resin contains additives that operate on a cellular level to continuously disrupt and prevent uncontrolled growth of microorganisms and biofilm within the cooling tower. The tower designs have a sloped basin and/or basin sweeper system to keep water from becoming stagnate, which can lead to microorganism development. Stagnant water areas are also prime breeding grounds for Legionella to grow. 800/289-3358; www.deltacooling.com.
