Heat Exchanger Trainer with PID Loop Control 

The transfer of heat energy between fluids is a very common industrial operation. The Heat Exchanger Trainer apparatus consists of six heat exchangers with associated fluid temperature indicators and flow-indicating controllers. The exchangers are of equal surface area with each one having unique features. Trainees are able to learn the impact of construction material, flow pattern or direction, turbulent or laminar flow, and exchanger design. 

Process Highlights:
  • Continuously variable water flow
  • Typical approach temperature difference 20°C to 50°C
  • Process (hot) water  - 0 to 6 USGPM - 0 to 23 l/m
  • Chilled water  - 0 to 6 USGPM - 0 to 23 l/m
  • DarbyTech
