Our locations

Your experts on your doorstep and worldwide

KORN products stand for quality and customised service worldwide – internationally and locally.

Together with our distribution partners in Canada, France, Switzerland and Poland, we not only supply first-class products, but also offer customised service – both internationally and locally.

Our long-standing partnerships are based on trust and shared visions. We specialise in water treatment for steam boilers, cooling towers, closed circuits and wastewater. By sharing our expertise and combining our resources, we create synergies that strengthen our distribution network in North America and Europe.

In addition, we actively collaborate on research and development to advance innovative solutions for water treatment.
