This paper experimentally investigates the control of an industry based shell and tube heat exchanger. The hot fluid outlet temperature in the shell side is maintained by manipulating the cold fluid temperature in the tube side. The Fuzzy Logic based Controller (FLC) has been implemented in a MATLAB environment using cost effective ADAM's module and compared with the Proportional - Integral (PI) controller. The performance of the controller has been investigated for multiple changes in set points and load changes. The fuzzy logic based controller has higher speed of response and the steady state error for the fuzzy logic control has a small average value than that of the PI control. There is less oscillatory behavior with the fuzzy logic controller, which allows a system to reach steady-state operating conditions in regions where PI controller is not able to perform well. The time domain specifications like rise time, settling time, overshoot and the performance indices, Integral Squared Error (ISE) and Integral Average Error (IAE) have been compared to PI controller.
