* The distribution unit of sprayed solutions is conventionally not shown;
** The unit of PH-control and dosing of absorbent solutions is conventionally not shown;
The body of the absorber consists of a bottom (input) part, a scrubber, a spraying unit of chemicals and an output part with a spraying system and a drop catcher.
The Fresh Air body assembled from the required number of sections is mounted on the support columns.
The Fresh Air unit has a possibility to install an additional insert up to 4 meters on the output section capping if it is necessary to increase the height of the emission point for neat process gases.
The outer and inner surfaces of bodies, structures and assemblies of the Fresh Air unit have
a paint coating with weather resistant paint. Сoating is not applied for stainless steel structures.
