BASCHILD PDK wood pre-drying kilns

PDK pre-drying kilns for wood

PDK is the name of BASCHILD pre-drying kilns.

PDK pre-dryers treat every type of wood essence, from an average thickness of 30 mm till beams (green timber stored).

Each kiln is specifically designed with a capacity from 300 m3 to 2.000 m3 net per cycle.

Timber is loaded frontally by forklifts.

The software BASCHILD ZOOM automatically manages the climate. 

The pre-drying kilns are made for the outdoor installation, despite the weather conditions.
