Wood-drying is based on the general principle that the material
to be dried has to be introduce into drying climate it can tolerate
– a climate able to absorb the water given off by the wood in such
a way that the planks don’t get damaged in the process.
Traditional fresh air or convection dryers are based on the simple
principle that the air ain a hot drying chamber absorbs more water
– i.e. steam – that the colder, outside air.
For example: if air with a temperature of –15 C and with a relative
humidity content of 90% is heated up to +48 C, that it’s relative
humidity content will drop to ca. 2%. This means that air in a chamber
with a temperature of +48 C is ready to absorb of further big amount
of water. This wet air is then extracted from the chamber and replaced
by drier external air.
Kentherm drying technology incorporates an important principle that
is often overlooked. The technical therm for the amount of heat
(humidity) carried by the prevailing air is “hidden heat”. The Kentherm
thermal condensator aims to make use of this ‘hidden energy” by
releasing it from the humid air – and at minimal energy cost
