KWI today

Our mission is to provide the best engineered and cost effective solutions for our customers in the field of liquid/solid separation, using DAF as the main process and to provide the best technical & maintenance backup service.
KWI has nine branch offices throughout Europe, the Far East and the Americas as well as agents and distributors in many other countries.


Since 1987 the KWI group has owned its own dedicated manufacturing and product engineering centre in Ferlach, Austria. The workshop manufactures all the equipment designed and sold by the KWI group of companies. 

The KWI group manufacturing centre is fully equipped in order to provide the best quality for our machinery.

The equipment is manufactured according to 2006/42/EC-Machinery (Annex II-B) regulation.



KWI has a research and development unit based in our Austrian Workshop where, thanks to the experience and feedback received from both our international offices and customers,  we are able to undertake product research programmes to develop new and innovative solutions. Our aim is to continue providing efficient, reliable & cost effective solutions to our customers needs. Latest innovations:
