Heat Exchanger : Concentric Tubes

DESCRIPTION

This unit uses an exchanger consisting of concentric tubes, which can work in counter-current (methodic) or con-current (anti-methodic) mode.

A tank equipped with an immersion heater permits the pre-heating of water with or without recycling.

A pump enables the flow of a fluid in the network or the agitation of the fluid.

The set is mounted on a mobile aluminium frame with wheels.

It is suitable for different levels and fields of studies.
