KTK: Material ⇒ Stainless steel
VDI 2047-2 recommends the use of corrosion-resistant materials in cooling tower construction.
At KTK Kühlturm Karlsruhe, not only the housing but also the water distribution and the nozzle tubes are made of stainless steel.
Stainless steel is corrosion resistant, has a smooth surface and is extremely easy to clean.
Germs and bacteria can adhere only very poorly to smooth surfaces.
