ZHAW, Wädenswil, Switzerland


The Uni­ver­si­ty of Applied Sci­en­ces of Zurich (ZHAW) is cons­truc­ting a new buil­ding for the Insti­tu­te for Food and Bevera­ge Inno­va­ti­on. A new bio­trans­for­mer was sup­plied by Cro­ma­tech for this pur­po­se. The bio­trans­for­mer is used to con­trol fer­men­ta­ti­ons (fer­men­ta­ti­on of wine, beer, cider, etc.) by con­nec­ting the exi­sting dou­ble jacket tanks to two dif­fe­rent cir­cuits — a coo­ling water cir­cuit and a hot water cir­cuit. The­se two cir­cuits (2 tanks) are con­stant­ly main­tai­ned at their respec­ti­ve tem­pe­ra­tures and read­ju­sted. In addi­ti­on, ano­ther tank is con­trol­led for CIP clea­ning. For which the neces­sa­ry regu­la­ti­on and con­trol system was created.
