As part of the treatment and cooling of air for sensitive industrial processes, Frigosystem has designed special equipment equipped with activated carbon filtering.

It is the most reliable high efficiency molecular filter for long-term control of molecular pollutants. They can also be used in odor removal applications in paper mills and wastewater treatment plants.

Specifically, Frigosystem creates specific combinations to be applied to the extrusion of the film, in order to decontaminate it from critical odors often absorbed by the surrounding environment.

Various sizes are available for modular and flexible assembly with variable absorption capacity according to the substances to be treated.

The batteries are already equipped with air connections for connection to the fans.

Absorption classes on activated carbon bed.

One way to give an idea of ​​the mass of pollutant that an activated carbon can adsorb is to divide the compounds into 4 classes with decreasing ease of absorption.



A = Substances with high absorption capacity by activated carbon (20-50%) *;

B = Substances with good absorption capacity by activated carbon (10-25%) *;

C = Substances with little absorption capacity by activated carbon (<15%) *;

D = NON-adsorbable substances by activated carbon.

* The percentages are not an index of absolute efficiency, but in relative weight, that is the quantity of contaminant that the filter can retain concerning the weight of the medium quality activated carbon present in the filter.
