The subsidiary Tana Chemie was established in 1971. Tana took on the specific task of manufacturing and marketing highly effective cleaning products for large-scale, professional users.

Almost 40 years later, Tana has numerous innovative developments to its name. Developments that have led the way in the cleaning and disinfection of hospitals and public buildings in western, eastern and south-eastern Europe. The company's progress has included the development of entirely new product areas, for example special cloths which complement cleaning chemicals as part of system cleaning solutions. But Tana's range of services is not limited to manufacturing. Large-scale consumers value Tana as a dependable partner, as a company that does more than just deliver cleaning products.

Tana can be relied upon for experienced and knowledgeable support, for example when it comes to drawing up cleaning schedules or to planning and carrying out staff training.
