2. Chamber description
A high level of precision, reliability, and safety for all growth parameters ensures optimum incubation
conditions. Moreover, the KB / KB-UL cooling incubator is designed for maximum usability – even in
continuous operation year after year. It fulfills all technical and application-specific requirements arising in
experimentation such as in the areas of biotechnology, medicine, the nutrition industry, pharmaceutical
and cosmetics industries, botany, and zoology.
Two important temperature technologies have been combined to achieve perfect temperature control. The
specially developed DCT™ refrigerating system, a direct refrigerating process, in conjunction with the
APT.line™ preheating chamber technology, satisfies the unique prerequisites for attaining highly-precise
temperature control and particularly short recovery times after opening the door.
The refrigerating system is distinguished by direct, precise, and rapid temperature conduction. Large-area
labyrinth evaporator plates directly conduct the cold to the atmosphere of the working space.
The APT.line™ preheating chamber system ensures high level of spatial and time-based temperature
precision, thanks to the direct and distributed air circulation into the interior. This is especially important for
maintaining temperatures – especially with full chambers – and for rapid restoration of optimum growth
conditions after opening the door. The inner glass door ensures that the temperature remains constant
when observing the incubation process. The fan supports exact attainment and maintenance of the
desired temperature accuracy. The fan speed is digitally adjustable. The heating and refrigerating systems
are microprocessor regulated to a tenth of a degree. In addition, the chamber provides almost unlimited
possibilities for adaptation to individual customer requirements based upon extensive programming
options and on the week program timer and real time clock of the controller.
All chamber functions are easy and comfortable to use thanks to their clear arrangement. Major features
are easy cleaning of all chamber parts and avoidance of undesired contamination.
The inner chamber, the pre-heating chamber and the interior side of the doors are all made of stainless
steel V2A (German material no. 1.4301, US equivalent AISI 304). The housing is RAL 7035 powder-
coated. All corners and edges are also completely coated.
The chamber comes equipped with a serial interface RS 422 for computer communication, e.g. via the
APT-COM™ 4 Multi Management Software (option, chap. 16.1).
Temperature range at ambient temperature of 25 °C / 77 °F: -5 °C / 23 °F up to +100 °C / 212 °F
