KB series:
Refrigerated microbiological incubators with program controller
KB is the all-rounder for microorganisms. With its wide range of individual programming functions, including a real-time clock function and an enormous temperature span from -10°C to 100°C, it can be used for a broad range of sophisticated applications in laboratories – with minimal dehumidification of specimens and impressive extra performance. The APT.line™ with its electronically controlled preheating chamber ensures rapid recovery times and maximum precision, unaffected by the ambient temperature.

Based on the ice increase on the evaporators the refrigerating capacity decreases at a set value of < 0 °C (32 °F).
For this reason the chambers have to be defrosted regularly (approx. once a week).
1) up to 98 % of the set value
2) not applicable for units with option independent adjustable temperature safety device 3.3
3) these energy consumption values can be used upon calculation of air conditioning systems
All technical specification are specified for units with standard equipment at an ambient temperature of +25 °C (68 °F) and a voltage fluctuation of ±10 %. The temperature data are determinated in accordance to factory standard following DIN 12880, part 2 respecting the recommended wall clearances of 10 % of the height, width and depth of the inner chamber. All indications are average values, typical for units produced in series. We reserve the right to alter technical specifications at all times.
