Via heat coils, axial fans blow circulation air through the timber. To achieve the best equalisation of moisture content, the air direction is reversed.

A third zone opens the possibility of using continuous kilns for drying to low moisture contents. Previously, this was something usually reserved for batch kilns. The conditioning zone is equipped with fans, heat coils, pressure frames, spraying/steaming equipment and its own ventilation. A door is installed between the conditioning zone and zone 2. Consequently, the conditioning zone’s climate can be regulated separately from that in the rest of the stainless steel kiln. Normally, the zone has two stations. Depending on loading intervals, this gives a conditioning time of 4 – 8 hours (see Technical solutions, pages 14 – 15). Timber types and capacity. As both FB and OTC models can be equipped with a conditioning zone, capacity can be up to 100,000 m3 (43 MMBF). All dimensions can suitably be handled and target moisture content can be down to around 8 – 18%. Our 3-zone continuous kilns add a further zone to the two found in our FB and OTC models. This zone has its own climate and is operated purely as a conditioning zone. This makes it possible to achieve better quality, even at really high capacities.
