Functioning And De-Humidification Performance; Installing The Device - HEYLO KT 1800 Bedienungsanleitung

2. Functioning and de-humidification performance

These HEYLO/DriEaz devices are cold dryers. They function through the blowing of
moist air out of the room through a cold humidification line. The moisture condenses on
the line, drips off and is then removed through the condensation conveying pump and
the drainage hose. The now warmer and drier air returns to the room and absorbs
water vapour again there.
If the dehumidifier functions at a room temperature less than approx. 20° C, frost will
normally form on the humidification line. The control electronics regularly interrupts the
de-humidification operation to thaw the evaporator. A considerable amount of water
runs out of the device during this time. As soon as the ice has melted, normal operation
starts again. How fast water is removed in all dehumidifiers depends on the air humidity
and air temperature. As far as possible, the performance of the dehumidifier must be
measured by how fast the air humidity drops and not by how much water is withdrawn
from it. The exact air humidity can be measured with a thermo hygrometer.
The device is fitted with an automatic hot gas thawing element. The device switches
itself off at regular intervals for a couple of minutes and thaws the frozen condensate
from the cold evaporator. This occurs by introducing hot gas into the evaporator. This
function enables extremely short thawing times and thus a high efficiency in the de-
humidification operation. Controlled by a thermostat, the device automatically starts
operation again, once the entire condensate has drained off.

3. Installing the device

The dryer should be operated in a closed room to achieve best performance. Close all
openings to other parts of the building, such as windows and doors, so that moist air
does not mix with the air in the areas to be dried. Open and close doors as little as
possible. A so called closed drying chamber is formed in this way. Use as many
devices as is required to achieve three times the air exchange.
Air should be able to circulate freely within the drying chamber. Open internal doors
and use fans to achieve good circulation of air in all areas. Install the dryer in such a
way that inflow of air is not limited by the inlet and outlet. Do not install close to loose
material, such as curtains, for example.
Normally, the dryer should be installed in the middle of the room. To dry a particular
spot, install the dehumidifier in such a way that the air let out is directed on the wet
area and the warm, dry air flows over it. The opening should be at least one metre
away from the wall.
The HEYLO/DriEaz dehumidifier heats the air from which it draws out moisture. The
temperature in smaller rooms can increase considerably due to this. Room
temperatures between 20° and 27° C generally provide good conditions for drying.
Room temperatures should not exceed 38° C and not be less than 1° C since the
dehumidifier will not work any more otherwise.
