Technical Cleaning I

Fluidised Bed

The Fluidised Sand Bed is a tank of sand which works at a temperature of 300 to 420ºC.

The sand starts to move when it reaches the specified temperature thanks to compressors which inject air and gas into the bottom of the tank.

The friction of the sand against the parts gradually eliminates any paint remains adhered to these. The organic material is absorbed whilst any gases emitted are burnt in the tank's afterburn chamber.

We have begun treating aluminium parts with outstanding results.

A study performed at the laboratories of the University of Navarra indicates that the material is not deformed in any way.

Pyrolysis Oven with After-burn Chamber:

This system is used for hard paint (i.e. when it is made with components which may harm the environment) in order to ensure the nonemission of volatile compounds.

The oven is a thermal, non-combustion oven. The oven maintains a constant temperature of 400º C which rises to 900º C for 2 seconds in the After-burn Chamber. When the set temperature is reached, a water spray is released inside the oven to prevent the part from catching fire and to reduce the emission of polluting gases.

When the basket is removed from the oven, the operator verifies that there are no areas on the part which have not been burnt. Following the cooling process, the part is fired to end the process.

The operator then visually checks that all of the part has been cleaned evenly and has not deformed.
