Scope of application
Sources of gas emissions "provide" an unpleasant odor in the area where foundries are located. In addition to phenol, formaldehyde, benzene, cyanides, polyisocyanate, amines, xylene, toluene, ammonia, methanol and other hydrocarbons resinous and suspended substances are present in the ventilation air at areas of pouring, cooling and knocking out stack molds. These substances condense on mold suspensions, cooling tunnel walls, air ducts, what excludes the use of "dry" filters for toxic gases neutralization. Long-term operation of the ABCU has confirmed that resinous and suspended substances do not affect the functionality of the ABCU.
