Our conventional dry kilns only use heat as an energy source. This system is very advantageous to companies that burn their sawdust or wood waste. They may also have inexpensive energy sources like hot water or steam.

Our conventional dry kilns are very well insulated and are absolutely vapour tight. The necessary air circulation fans and heaters are mounted 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 relative humidity and temperature. When the desired temperature and relative humidity are achieved, depending upon the type of timber being dried, the computer will open the modulating ventilation system. An amount of hot wet air will be vented to the outside. The same amount of fresh outside air will enter the dry kiln. This air is heated and is able to absorb moisture from the timber again.

Because of this drying process, the relative humidity and moisture content of the timber will be reduced until the desired moisture content within the timber is achieved.
