Shell and tube heat exchangers are in widespread use. The main advantages of this design are the large heat transfer surface and the compact design. Shell and tube heat exchangers are used in the chemical and pharmaceutical industries, in refineries and in process engineering plants.
The shell and tube heat exchanger WL 110.03 consists of seven tubes, surrounded by a transparent outer shell. The hot water flows through the tube space and the cold water through the space in the shell. Part of the thermal energy of the hot water is transferred to the cold water. Baffle plates are used to deflect the flow in the shell in such a way as to create greater turbulence and thus a more intensive transfer of heat. The supply hose can be reconnected using quick-release couplings, allowing the flow direction to be reversed. This allows cross parallel flow or cross counterflow operation.
During experiments, temperature curves are plotted and displayed graphically. The mean heat transfer coefficient is then calculated as a characteristic variable.
The accessory WL 110.03 is easily and safely positioned on the worktop of the WL 110 supply unit. Via RFID technology the accessories are automatically identified, the appropriate PLC software is loaded and an automatic system configuration is performed. The intuitive user interface guides through the experiments. For tracking and evaluation of the experiments, up to 10 external workstations can be used simultaneously using the local network via LAN connection.
Temperature sensors for measuring the inlet and outlet temperatures are located at the supply connections of the WL 110. The supply of hot and cold water, the flow setting and the measurement of inlet and outlet temperatures are carried out via the supply unit.
