Cold smoking chambers from AUTOTHERM can be easily installed in existing rooms. The air treatment takes place outside the chamber, optionally behind, next to or on the chamber ceiling. A continuous air-reversing flap ensures a constantly alternating air supply between the two especially designed and adjust- able supply air ducts. The intake through a return air duct ensures uniform and optimum air circulation. This concept ensures absolutely uniform ambient conditions – which are required for top quality products. Energy saving technology such as the external air control (CES) , processor controlled process optimisation (AEC) and speed control for the air circulation fan can be installed on request. The units are also equipped with an automatic cleaning system for the interior and smoke ducts. A microprocessor controls the whole program sequence and the process parameters. Various smoke generators from the AUTOTHERM product range are available. Exhaust air cleaning systems can be added to eliminate the smoke.
