The reactor is the core element of a chemical production facility. In the reactor, the starting substances (reactants) react with each other to form a new substance (product). The reactor has to guarantee the conditions for an optimal reaction process. This primarily concerns the temperature in the reactor. Different types of reactors are used, depending on the requirements. It serves as a supply unit for six different reactors. The reactor to be examined is mounted onto the supply unit and held by 2 pins in position. For continuous operation of the reactors, two tanks for the reactants are arranged on the trainer. The supply unit and the reactor are hydraulically connected via hoses. The hoses are equipped with quick-release couplings for easy attachment. Two pumps convey the two reactants into the reactor. The retention time of the reactants in the reactor can be adjusted via the pump speed. In the reactor, the reactants react to form a product. An additional tank and an additional pump for the product is provided. The supply unit is equipped with a heating water circuit with pump, tank and heater to control the temperature in the reactor. The cold water circuit can be fed from the Water Chiller. Conductivity and temperature in the reactor are measured with a combined sensor. The switch cabinet contains the necessary controls to start the stirrers in the different reactors. The measured values are digitally displayed on the switch cabinet. At the same time, they can also be transmitted directly to a PC via USB where they can be analysed with the data acquisition software included in the scope of delivery. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
