WL 315C Heat Exchanger Trainer
Education / GUNT Hamburg / Thermal Engineering and HVAC / Applied Thermodynamics /

This trainer compares tubular, shell and tube, finned cross-flow (water-to-air) and plate heat exchangers. A jacketed vessel with stirrer and tube coil is also included. To perform the experiments the individual heat exchangers can be conveniently selected using valves on the front of the trainer.

  Comprehensive instrumentation provides temperature and flow rate data. The measured values are transmitted directly to a PC via USB. The data acquisition software is included.

  A supply of hot and cold water is necessary for operation. This can be provided from the supplies in the laboratory or using the accessories for hot water supply (WL 312.10) and cold water supply (WL 312.11).
