PIGNAT Three Exchanger Test Rig – BET3000


SKU: BET3000 Categories: , , Tags: ,


Compare three industrial heat exchangers with identical surface areas: 0.5 m²

  • Two technology (tubular, plates) with the same material
  • Two materials (stainless steel, glass) with the same technology

Heat exchangers

  • The design of this unit allows the study of three industrial exchangers with identical surfaces:
    • A plate heat exchanger
    • A glass shell and SS tube heat exchanger
    • A glass shell and glass tube heat exachanger
  • Two three‐way valves allows the study in co‐current and counter-current flow in each heat exchanger

Study the parameters affecting heat transfer:

  • Exchanger materials: glass, stainless steel
  • Regime: turbulent, laminar
  • Circulation: co-current, counter-current
  • Thermal transfer fluid used: hot water, steam

Characterize and compare heat transfers:

  • Thermal balance
  • Yield
  • Overall experimental and theoretical heat exchange coefficient K

Study the condensation of steam

General Specifications

  • ECH1: plate exchanger, stainless steel.
  • ECH2: glass/stainless steel exchanger, SURLYN coated. Tube with baffle-plates, composed of SS tubes
  • ECH3: glass/glass exchanger, SURLYN coated. Tube with baffle-plates, composed of glass tubes.

For each of these three exchangers:

  • Two three-way valves for selection of the direction of circulation.
  • Heating unit .
  • Steam circuitry: flowrate and bottling of condensate setting valves.


  • Temperature probes Pt100Ω.
  • Flowmeters:
  • Manometer.
