Product Details

Technical Description
Using this benchtop unit the complex area of convective heat transfer can be investigated experimentally. Different heat exchanger modules (accessories) can be easily connected to the service unit, which includes a hot water tank with electrical heater and pump. The hot water temperature and the cold and hot water flow rates can be adjusted. The relevant temperatures and flow rates are measured using sensors and indicated on digital displays. It is possible to process the measured values on a PC using the data acquisition card and software (WL 110.05). A supply of cold water (mains or WL 110.20) is required. 

Learning Objectives / Experiments
- Function and operating performance of heat exchangers:
  + Tubular Heat Exchanger (WL 110.01)
  + Plate Heat Exchanger (WL 110.02)
  + Shell and Tube Heat Exchanger (WL 110.03)
  + Jacketed Vessel with Stirrer and Coil (WL 110.04)
- Temperature curves in parallel flow operation
- Temperature curves in counterflow operation
- Comparison of different types of heat exchangers

* Service unit for various types of heat exchanger
* Optional processing of measured data on a PC
* Water connections using quick-action hose couplings
