UHT Test plant of the dairy school

Dairy specialists and engineers at the Bavarian State Institute for Agriculture in Kempten (a teaching, testing and technical centre for the dairy industry) have a new and innovative UHT-ESL testing plant at their disposal for training purposes in the college. In collaboration with plant engineers, the latest technological concepts and components have been developed and integrated into the plant. GEMÜ supplied not only globe valves, ball valves and aseptic diaphragm valves, but also the appropriate multi-port valve blocks made of stainless steel.
