Hygiene in cooling water systems is not only a technical challenge, but also a legal obligation. Since the 42nd Federal Immission Control Ordinance (42nd BImSchV) came into force, strict requirements apply to operators of evaporative cooling systems and cooling towers. Legionella in cooling water poses a significant health risk – VDI 2047 therefore defines clear requirements for cooling water hygiene.

WM Aquatec offers VDI 2047-compliant solutions for cooling water treatment in evaporative cooling systems. Our UV-C disinfection reliably eliminates Legionella and other microorganisms – without aggressive biocides that attack materials and burden the environment.

Biofilm formation in cooling circuits is a common problem: biofilm reduces heat transfer, increases energy consumption and provides ideal growth conditions for Legionella. Our silver ion technology sustainably prevents biofilm and protects your cooling systems from deposits.

The 42nd BImSchV requires complete documentation of all hygiene-relevant measures. Our systems automatically log all operating parameters and support you in meeting your documentation obligations. This ensures you are optimally prepared for authority inspections.
