Description

The GPCFL2 bench allows the study of fluidization.

After expansion of the compressed air 1, we dry the air through a line cartridge 2 in order to improve the subsequent drying.

Then we heat the air in an air heater 4: the output temperature is regulated, the humidity input and output are measured.

The air arrives in the enclosure 5 hot and dry, it fluidizes the humid alumina and dries it

We control the pressure losses as well as the moisture input and output of the container 5.

The air exits cooled and passes into a cyclone in order to send air free of dust in the atmosphere.

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

Its anodized aluminum structure on wheels makes it very robust as well as a great flexibility of integration into your premises.

The manufacture 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.
