MULTI - EXCHANGERS

BMV/3000 THERMAL HEAT EXCHANGERS

➢ Compare three industrial heat exchangers having the same
exchange surface area and different technologies

Compare the three technologies
Single-tube glass/stainless steel heat exchanger
Shell-and-tube heat exchanger with glass shell and stainless steel tubes
SS plate-type heat exchanger

Determine the influence of flow regimes on heat transfer
Turbulent and laminar regimes
Co-current and counter-current circulation
Study of temperature gradient (optional).

On each circuit two rotameters of different range and allow exact reading to
minimum flow.

The selection valves allow the selection of the heat exchanger to study and

The exchangers have glass outer shells revealing their internal design.

The thermal transfer is possible thanks to the temperature probes at the inlet Flow transmitters
and outlet of each exchanger.

Options
Study of the temperature gradient ECH1
Adding 3 Pt 100 Ω temperature probes on each fluid.

Flow transmitter flowmeters replacement by
transmitters allowing the data acquisition.
