Global expansion

From the very beginning, it was one idea (1926) above all that shaped our current corporate DNA. After all, anyone who deals with rust protection by nature is committed to maintaining the value and care of their customers' equipment. Over the years, this aspiration has not only given rise to considerable chemotechnical knowhow, but perhaps an even more important quality: the ability to listen. It is not by chance that KEBO sees itself today as a solution provider. And above all as a partner with special connections to its customers, with a great deal of commitment and personal consultation in solving very individual challenges. In 1926, Keller & Bohacek was founded as ""Rostschutz GmbH"" with a focus on the construction of galvanizing plants in Halle. At an early stage, our founder Dr. Alfred Keller, an engineer by passion, decided to enter the production of pickling inhibitors and thus laid the foundation for today's orientation as a specialized chemical company. Alfred Keller's daughter Renate joined the company in the 1950s as a chemist. From then on, she was the driving force behind the development of innovations and was regarded as the ""heart and soul"" of KEBO. Parallel to the development of products for chemical plants, steel industry and sugar factories, the field of cooling water and boiler feed water treatment was then worked on. The existing vast experience in corrosion protection as well as in scale prevention led to the development of effective water conditioners and scale inhibitors. Today, KEBO operates worldwide to meet present challenges on behalf of its customers.

The products shown on our website are only a selection of our entire product range. There is no universal remedy for the rapid removal of impurities. Some can be removed well with alkaline agents, others better in the acidic range. The large variety of conceivable cleaning problems and the large number of additives, inhibitors and ready-to-use cleaning solutions offered by us make it advisable to obtain detailed advice before starting cleaning.
The same applies to inhibitors, defoamers, scale preventers, corrosion inhibitors, pickling inhibitors, etc. Depending on the plant, material, product and the type of boiler/cooling water is used, different individual challenges arise. We are well equipped for them.

Talk to us, we will be happy to help!
On request, we can analyze deposits in our laboratory and develop a cleaning strategy based on our many years of experience, taking into account the conditions on site.
