The plates are soldered in such a way that two separate flow channels are The plate heat exchanger is connected to the supply unit using the quick-release couplings. The separators of the supply unit are used to adjust the flow rates of The supply sensors can be reconnected using quick-release couplings, allowing the flow direction to be reversed. The allowing sensors for measuring the inlST and outlST temperature are located at the supply connections on The plate heat exchanger.

The key feature of plate heat exchangers is their compact design, in which optimum use is made of all of the material for heat transfer. The pressed in profile on the plates creates narrow flow channels, in which significant turbulence occurs. The turbulent flow allows effective Heat transfer even with low flow rates and also has a self-cleaning effect. Plate heat exchangers are used in the food industry, offshore technology, refrigeration and domestic engineering. The experimental unit is ideally suited for investigating the functioning and behaviour of a plate heat exchanger in operation.

During experiments, temperature curves are plotted and displayed graphically.
