Heat Exchanger Demonstrator
Description: The heat exchanger demonstrator consists of two heat exchangers with associated temperature indicators, flow indicators and a temperature indicating controller. A valve is provided to reverse the tube-side flow direction. The two exchangers are of similar surface area but with unique design features.
- Single pass shell and tube exchanger – brass
- Plate exchanger with stainless steel plates
Temperature and flow data obtained can be used to calculate energy balance, heat transfer and heat transfer coefficients.
Function: The exchanger demonstrator is connected to hot and cool tap water. 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. Trainees select exchanger type, flow direction and flow rate then read and record the flows and temperatures for further analysis.
Equipment Specification Highlights:
- Process water flow rate is controlled with flow meters and manual control valve
- Cooling water flow is controlled with PID controller and control valve based on process discharge temperature
- 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
- Approximate overall dimensions – 80 x 45 x 120 cm high (32” x 18” x 48” high)
Options:
- Pneumatic or electric modulating solenoid control valve
- Closed loop process (hot) water circuit using an electric heater and circulation pump
Models: Single-phase electrical power (except CL):
- Model HE30-240-** is for 240VAC 50 Hz
- Model HE30-120-** is for 120VAC 60 Hz
- option code
- P - pneumaic valve
- E - electric valve
- CL - closed loop process water (three-phase power required)
