12.1 Function of the humidifying and dehumidifying system
Humidifying system
The humidifying system is located in the humidity generation module. In a cylindrical container with a vol-
ume of about 2 liters an electrical resistance heating evaporates water. The produced steam is maintained
on a stable pressure level and is thus available in sufficient quantity for rapid humidity increases or for
compensation of humidity losses, e.g. by door openings. Condensation forming on the outer walls of the
useable volume is led through a water drain in the outer chamber into the wastewater can which is
pumped off automatically to the wastewater pipe when required.
Freshwater
You can supply the unit with freshwater via a water pipe or by manually filling a freshwater can (option,
chap. 15.9) You can mount the can on the rear of the unit or place it next to the unit.
In order to ensure accurate humidifying, observe the following points with regard to the
freshwater supply:
• Supply pressure 1 to 10 bar / 14.5 to 145 PSI when connecting to a water pipe
• Water type: deionized (demineralized) water
• To ensure humidification during 24 hours even at high humidity set-points with manual wa-
ter supply, we recommend filling the freshwater can (option) at the end of each day.
• Water intake temperature NOT below +5 °C / 41 °F and not exceeding 40 °C / 104 °F .
BINDER GmbH is NOT responsible for the water quality provided by the customer.
Any problems and malfunctions that might arise following use of water of deviating quality is
excluded from liability by BINDER GmbH.
Automatic freshwater supply via water pipe
With this type of supply, the humidity system is continuously functional.
Manual freshwater supply via freshwater can (option, chap. 15.9)
With this type of supply, the humidity system is functional only if the water can is sufficiently filled. Check
the filling level daily. The water reserve in the can is sufficient for a period, which may last between one
and several days, depending on the humidity demand (entered humidity set-point and number of door
openings).
Wastewater
The condensation water from the interior is collected in an internal can with a volume of approx. 0.5 liters.
It is pumped off via the wastewater pipe.
Dehumidifying system
When humidity switch “ON / OFF” (4) (located on the right lateral control panel) is “ON”, the climatic
chamber KBF dehumidifies as needed in order to reach the entered humidity set-point” inside the control
range of temperature and relative humidity (Figure 21).
Dehumidification occurs in case of need by means of defined dew point undershoot of several evaporators
of the refrigeration system. The condensate which forms is carried away as wastewater.
If the humidity system is turned off while there are descending temperature curves, then operation of the
refrigeration system may cause dehumidification of the charging material.
