The experimental unit can be used to demonstrate boiling and evaporation processes in a straightforward manner. The processes take place in a transparent tank. A condenser in the form of a water-cooled tube coil ensures a closed circuit within the tank. Special liquid is used as evaporating fluid. Compared with water, this liquid has the advantage that its boiling point is at 36, 7°C, whereby the evaporation process takes place at much lower temperatures and a lower heating power.
Sensors record the flow rate of the cooling water, the heating power, pressure and temperatures at all relevant points. The measured values can be read on digital displays.
