All technical data is specified for unloaded units with standard equipment at an ambient temperature of
+25 °C / 77°F and a power supply voltage fluctuation of +/-10%. The temperature data is determined in
accordance to BINDER factory standard following DIN 12880, observing the recommended wall
clearances of 10 % of the height, width, and depth of the inner chamber. Technical data refers to 100%
fan speed.
All indications are average values, typical for units produced in series. We reserve the right to
change technical specifications at any time.
Refrigerating performance decreases while operating the chamber at temperatures < 0 °C /
32°F due to icing of the evaporators. For this reason defrost the chamber regularly, e.g. once a
week.
If the chamber is fully loaded, the specified heating up and cooling down times may vary
according to the load.
