A plate heat exchanger commonly referred to as PHE plays a major part of the brewing system as it rectifies the temperature of the transferred wort to the fermenters. The PHE is basically a heat exchanging medium which drops the temperature of prepared wort which is at a temperature of 80 ~ 100 degrees to 17 ~ 20 degrees during transfer to the fermenter. The control of this temperature is very important for the role of the yeast
