Pressure drying
For pressure drying of layered constructions such as floating floors, the CTR A ES is used with one or
more turbines from the Corroventa product portfolio, in accordance with the schematic sketch
below. Pressure drying is two to four times faster than suction drying and is therefore, whenever
feasible, the primary choice unless mould or fibres are present.
Pressure drying means leading dry air from the CTR A ES to a turbine and applying that to push the
air into the layered construction. This way, hot and dry air will travel through construction making
itstemperature rise which increases the speed of the drying process. Wet and cooled air exits the
construction through drilled outlets or through the gaps between the floor and the walls and then
returns to the dehumidifier as process air.
Before pressure drying is applied, suction drying should be used to evacuate any free water and
prevent this from being pushed into other parts of the construction/building. When setting up the
machines for pressure drying, it is very important to check turbine is not pulling more air from the
dehumidifier than it can deliver. Therefore, always verify that the wet air volume is in balance with
the dehumidifier. When using a CTR ES version turbine, this machine is preferably set to flow mode
so that it maintains constant air flow. There is also the possibility of networking the two units, using
the turbine as Master, and setting up the adsorption dehumidifier slave to pressure drying mode
where it automatically adjusts the wet air volume to requirements. Still, always check the status of
the units before leaving the site so that the installation works as intended. Furthermore, please note
that the Extra Heater available with the CTR A4ESX must not be used when the dry air is led to a
turbine as this will cause overheating.
Pressure drying might free particles/fibers from the construction and thus release them in the air. If
this is a potential problem, another method, e.g. suction drying, should be applied.
Pressure drying. The turbine is fed with dry air from the dehumidifier and presses this air into the
layered construction.
