The unit consists of the three heat exchangers, and a service module. The module comprises a hot water tank with a transfer pump and instruments for monitoring and control. The Multi Heat Exchanger apparatus is used for studying of three types of heat exchangers namely-concentric tube, shell and tube, and plate-under parallel or counter flow conditions. The unit requires outside water supply. Changing from one type of heat exchanger to another is by rearranging flexible hoses and changing from parallel to counter flow is by switching two cold water hoses.
Experiments:
Demonstration of heat transfer under parallel or counter flow.
Effects of flow rate and temperature difference.
Demonstration of batch type heat transfer for jacketed vessel.
Comparison of heat transfer coefficients for concentric tube, shell and tube, and plate heat exchanger.

The bodies used in the experiments have strong steel hooks for attachment to the suspension cords. The length of the cords can be rapidly changed and securely fixed using clamping wheels. The model permits oscillations on pendulums with bifilar or trifilar suspension to be investigated. The beam can oscillate, by translation, in the plane of suspension like an ideal mathematical pendulum. The cylinder and the circular ring work as rotary pendulums. For this purpose a bar, a cylinder, or a hollow cylinder made of galvanised steel can be hung from a wall mounted carrier plate made of aluminium and placed in oscillation.
