Heat exchanger - water/vapour

DESCRIPTION

Water is heated by an electric resistance element in a closed glass chamber and is converted into vapour. This vapour condenses when it contacts copper tubes containing cold circulating water.

The unit is properly equipped with the instrumentation required to measure various parameters and deduce the heat exchanged under various cooling configurations (temperature – flow – pressure).

The BET 020 equipment is delivered fully equipped and includes a technical manual as well as instructions.
