This company’s Sanipacking fills (photo) prevent the growth of bacteria and reduce the risk of Legionella bacteria in wet cooling towers with open circuits. Sanipacking fills also prevent colonization of the fill surface by the microbe Pseudomonas aeruginosa, the species most frequently found in the biofilm of industrial cooling water. To maintain the full antimicrobial effect for three to five years, it is necessary to keep the surfaces of the fills free of inorganic encrustation with effective water treatment and regular maintenance. The impact-resistant and pressure-stable Sanipacking fills consist of special individual polypropylene films that are systematically sealed together to form stable modules with a cross-fluted structure. In addition, high-efficiency NET150 splash fill packs are available with Sanipacking materials. The honeycomb-shaped modules can operate with effective resistance under water temperatures of up to 80°C. The material does not contain arsenic or heavy metals, and is resistant to fouling, fungal effects, corrosion and UV radiation. — Enexio Management GmbH, Herne, Germany
