13.1 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
volume of about 2 liters an electrical resistance heating evaporates water. The water content is kept ex-
actly at the boiling point, and thus steam can be immediately generated 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. 17.9) You can fix the can on the unit rear or place it next to the unit.
In order to guarantee perfect humidifying, observe the following points with regard to
the freshwater supply:
•
Supply pressure 1 to 10 bar when connecting to a water pipe
• Water type: deionized (demineralized) water
• To guarantee humidification during 24 hours even at high humidity set-points with manual
water supply, we recommend filling the freshwater can (option) daily at the end of the 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 at 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 fresh water supply via freshwater can (option, chap. 17.9)
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 water can is sufficient for one up to several days, depend-
ing on the humidity demand (set humidity set-point, 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 waste water pipe.
Dehumidifying system
When humidity switch ON / OFF (4) (located on the lateral control panel) is in position ON, the constant
climate chamber KBF LQC dehumidifies in case of need in order to reach the set humidity set-point inside
the Control range of temperature and relative humidity (Figure 22).
Dehumidification occurs in case of need by means of defined dew point undershoot of several evapora-
tors of the refrigeration system. The condensate which forms is carried away as waste water.
If the humidity system is turned off, at descending temperature courses dehumidification of the charging
material is possible due to operation of the refrigeration system.
