Laminar flow atmosphere

2700 dm³ one-piece environmental chamber intended for tests in laminar flow atmosphere, within a temperature range from +20 to +60°C, with air speed rates inside the volume between 0,3 and 0,5 m/s during plateau.

This chamber has been designed to simulate conditions of electrical cabinets and to watch apparatus behaviour.

A big frame, sticking out on the left, enables the integration of an electric process command box.

Air circulation

 

The ventilation system has been optimized a great deal in order to get slow air speeds in association with homogeneity below 1°C.

Air circulates only one way, from the bottom to the top, in order to recreate natural convection.

This chamber has been verified with 15 probes (in accordance with international standards) and also with a hot-wire anemometer.

 

The flow has been specially studied to stand the weight of two men while letting the air flows through.
