The air purification in an electrical clean room must be carried out with extreme precision. To achieve this, it is essential to understand the specific requirements of this application, starting with the calculation of heat loss in the operating rooms. This calculation takes into account parameters such as specific heat, the required amount of fresh air, and battery power to ensure continuous operation.

Two Methods

To treat smoke pollutants, two approaches are commonly employed. The first involves capturing the pollutant by accumulating it on a support, such as activated charcoal. This method traps harmful substances present in emissions.

The second approach entails chemical neutralization of the pollutant using a compound added to the support. In this case, chemical filtration modules in the form of granules are used. These granules contain chemical reagents capable of reacting with pollutants, transforming them into less harmful or innocuous compounds.

When smoke flow rates and pollutant concentrations are higher, it is necessary to opt for a more robust solution. This involves installing a dust removal system with the injection of an appropriate product, often lime.
