GEA Tuchenhagen's new VARIPURE cleaners for tank and vessel cleaning, as well as for special applications, can help you to make an important contribution to protecting the environment and also to save on investment costs. In hygienic processes, tank cleaning priorities have changed during the past years. In the past, the most important task was to have a clean tank after being subjected to a certain cleaning method, but today a higher awareness of environmental as well as economical issues do play a decisive role also.
