Pressure drying
When pressure drying, use CTR A together with a turbine according to the schematic diagram below.
Pressure drying is two to four times faster than suction drying and is therefore the primary choice for
a layered structure, if there are no obstructions.
Pressure drying. The turbine is fed with dry air from the drier and forces
it into the layered structure.
During pressure drying, dry air is routed from CTR A to a turbine and then forces this air into the
layered structure. In this way, warm and dry is forced down into the structure, which achieves the
material temperature and thus increases the rate of the drying process. Wet and cool air leaks into
the room through the gaps between the floor and the wall or via drilled check holes, and is then re-
sucked into the drier as process air.
Before starting pressure drying, suction drying is required to evacuate all free-flowing water so that
this is not forced into other parts of the structure. Furthermore, it is important to balance the turbine
capacity with the drier's so that not too much air is drawn through the latter, which interferes with
its function and performance.
Pressure drying may release fibres/particles from the layered structure into the indoor air and if this
is a potential problem another method should be applied.
