Cooling towers & evaporative cooling systems
Under certain conditions, evaporative cooling systems, cooling towers and wet separators can release water droplets (aerosols) that contain legionella into the air which, when breathed in by humans, can cause severe pneumonia and can even result in fatalities. The Ordinance on Evaporative Cooling Systems, Cooling Towers and Wet Separators (42nd BImSchV) and the VDI 2047 "Recooling Plants – Assurance of Hygienic Operation of Evaporation Coolers" standards define the national technical and organisational obligations etc. for the correct operation of such systems.
Cleaning and maintaining evaporative cooling systems, wet separators and cooling towers is challenging. Many different technical circumstances and environmental conditions, areas that are difficult to access, the use of various biocides and the handling of biological agents, e.g. in biofilm, represent substantial challenges for specialists' processing technology and qualifications.
