Teaching suggested applications*

-          Visualization of boiling and condensation processes

-          Effect of temperature and pressure on the evaporation process

-          Highlighting of the increased efficiency of the heat exchanger with the increased of number of interchange circuits for a constant flow rate

-          Measuring the effect of the increase of the flow velocity of the cooling fluid and the number of interchange circuits on the heat transfer coefficient

-          Study of the relation pressure/saturation temperature for water at low pressure

Description

The BET 020 bench allows to study the vaporization of water vapor and thermal water exchanges on a tube exchanger. The bench is composed of a pressure vessel containing heated water which will turn into steam. The steam will heat exchanger with the stainless steel pipes inside which cooling water circulates. The unit BET 020 is very instrumented (measurement temperature, flow, pressure) to deduce the thermal exchanges using several cooling configurations. The robust design of this equipment makes it perfectly suited for school use.

Its anodized aluminum structure makes it very robust as well as a great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive.
