Parallel & Counter Flow Heat Exchanger Apparatus

Parallel and Counter Flow Heat Exchanger Apparatus Manufacturer, Supplier and Exporter – Designed for engineering and heat transfer laboratories, this apparatus is used to study heat transfer in both parallel flow and counter flow heat exchangers. The setup features a concentric tube heat exchanger with controlled hot and cold water circulation, enabling students to compare the performance and thermal characteristics of both flow arrangements.

Experiments:

• Determination of heat transfer rate

• Calculation of Log Mean Temperature Difference (LMTD)

• Determination of overall heat transfer coefficient

• Comparison of the performance of parallel and counter flow heat exchangers
