Heat Exchanger Demonstrator

Temperature and flow data obtained can be used to calculate energy balance, heat transfer and heat transfer coefficients.
A valve is provided to reverse the tube-side flow direction. The two exchangers are of similar surface area but with unique design features. The Heat Exchanger Demonstrator consists of two heat exchangers with associated temperature indicators, flow indicators and a temperature indicating controller. 
Plate exchanger with stainless steel plates
Single pass shell and tube exchanger brass

Function:
The Heat Exchanger Demonstrator is connected to hot and cool tap water. Trainees select exchanger type, flow direction and flow rate then read and record the flows and temperatures for further analysis. Process (hot) water flow is manually controlled. Cooling water flow may be either manually controlled or automatically controlled to a selected process temperature set-point.

Process water flow rate is controlled with flow meters and manual control valve
Temperature measurement of inlet and discharge waters
A valve is provided to reverse the tube-side flow direction.
Mounted on a cart for ease of movement and storage
Cooling water flow is controlled with PID controller and control valve based on process discharge temperature
Approximate overall dimensions 80 x 45 x 120 cm high.
