Description

The BEC 010 allows the study of condensation. It consists of a main tank containing water. This water is heated and transformed into vapor.

The vapor will surround two condensers of different material (a copper condenser and a second with a gold coating) and to transform in liquid again.

Each condenser is designed to produce a different type of condensation: film and droplets.

The installation is very instrumented and can measure all the operating parameters (temperature, flow rate, pressure) to derive the heat exchanges according to several configurations. It is also equipped of a data monitoring with Didatec interface included.

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminum frame with legs gives it great robustness as well as a great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive.

The bench is installed on an aluminum profile structure equipped with four directional braked casters.

It has an electrical box with a main power disconnect switch and a 30mA differential circuit breaker.
