The 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 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. Selection of the heat exchanger is simply done by opening a valve and changing from parallel to counter flow is by switching two flexible hoses. The unit requires outside water supply.

  • Comparison of heat transfer for concentric tube, shell and tube, and plate heat exchanger.
  • Demonstration of heat transfer under parallel or counter flow.
  • Demonstration of batch type heat transfer for jacketed vessel.
  • Determination heat transfer coefficient.
  • Effects of flow rate and temperature difference.
