20. Defrosting at refrigerating operation
BINDER cooling incubators are very diffusion-proof. In favor of the high temperature accuracy, no automatic
cyclical defrosting device is used. At very low temperatures the moisture in the air can condense on the
heat sinks leading to icing.
Always close the door properly.
Operation with temperature set-points above +5 °C / 41 °F at an ambient temperature of 25 °C / 77 °F :
The air defrosts the ice cover automatically. Defrosting is continually performed.
Operation with temperature set-points below +5 °C /
41 °F
:
Icing on the heat sinks is possible. Defrost the chamber manually.
With temperature set-points below +5 °C /
41 °F
, regularly defrost the chamber manually:
•
Set the temperature to 40 °C /
104 °F
.
• Let the chamber operate for about 30 minutes with the door closed.
Too much ice on the heat sinks is noticeable by reduced refrigerating performance.
21. Anti-condensation protection
Depending on the load, for example with a large number of Petri dishes, a lot of moisture can be released
in the interior of the chamber. One of the Peltier modules ensures that the humidity is limited. With the “Anti-
condensation protection” function, you can adjust the degree of dehumidification in order to reduce con-
densation.
Path:
Normal display Settings Various Anti-condensation
Press the OK button to enable the setting.
Setting the anti-condensation protection
The current setting flashes. Enter the desired intensity of the anti-con-
densation protection with the arrow buttons . Entry range: 0 % up to
100 %.
Confirm the entry with the
OK button .
Anti-condensation
With the arrow-up button you can go back to the temperature tolerance range setting (chap. 13.2).
With the
Back button
you can go back to the “ Various ” submenu and, repeatedly pressing it, to Normal
display
.
Information on the setting
Factory setting is 40% intensity. This setting is suitable for most applications.
If a higher level of humidity in the interior leads to condensation, the intensity of the condensation protection
can be increased, thereby preventing condensation on the door and in the interior. However, this also
slightly increases the energy consumption.
The intensity can be reduced for applications with low humidity introduction, which also lowers energy con-
sumption. The most energy-saving setting of 0% is suitable for applications without humidity introduction.
