Our conventional dry kilns only use heat as an energy source. This conventional system is mostly delivered at customers who have a hot water or steam boiler. Our conventional dry kilns are very well insulated and their walls are absolutely vapour tight. The kilns are complete with air circulation fans and heater between the roof and the double ceiling.

Principle

The air in the dry kiln is heated and circulates through the stacked timber. The air will slowly rise in temperature and relative humidity. When the air reaches the set point (depending of the type of timber), the control system will open the exhaust valves. A small amount of the hot wet air is vented to the outside. The same amount of fresh outside air is entering the kiln again. This fresh air is heated and therefore the relative humidity will drop. In this way, the water in the timber will be evaporated, which causes the moisture content in the timber to fall. This process will be done till the desired final moisture content in the timber is reached.
