The Maurer Atmos Climate Industrial Cold Smoking Systems are suitable for fermenting, cold smoking, drying and maturing. The circulating air is a multiple channel system compromised of air supply and return air channels. The systems also have horizontal and vertical air distribution systems, ensuring a thorough air circulation. The circulating air is prepared through a central air handling unit and is blown into the processing room through air injecting ducts. Through the centrally positioned air suction duct, the circulating air is returned back in the central air handling unit. The circulating air injection can be variably adjusted to the room.
