Description of Technology

All devices that evaporate water for cooling, including cooling towers, have to deal with limescale, corrosion and microbiological growth. These three problems are usually treated by adding chemicals to the cooling water. Pathema has long proven that cooling water can be treated completely chemical-free. The alternative method that Pathema has developed to tackle limescale, corrosion and microbiological growth is their Industrial Vortex Generator-Circulation (IVG-C). Because no more chemicals are used, the IVG-C provides a sustainable solution, and the drainage water can be safely removed or reused for other purposes.
