Shell and Tube Heat Exchanger are popular in process industries because they occupy less space and offer reasonable temperature drop. The apparatus consists of fabricated shell, inside which tubes with baffles on outer side are fitted. The present set up is a 1-2 heat exchangers, with cold water flows through shell and hot water inside the tubes. For hot water, a recirculation type water tank is provided, fitted with heaters and Digital temperature controller. Cold water at constant head condition is to be provided from laboratory overhead tank by the end user. Flowrates of hot and cold water are measured using Rotameters. A magnetic drive pump is used to circulate the hot water from the re-circulation type water tank. Digital temperature indicator with multichannel switch is fitted in control panel to observe the temperature of hot and cold fluids at inlet and outlet of heat exchanger.

• An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.
• The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.
