2. Chamber description
A high level of precision, reliability, and safety for all growth parameters ensures optimum incubation con-
ditions. Moreover, the KB cooling incubator is designed for maximum usability – even in continuous oper-
ation 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 de-
sired 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 op-
tions and on the week program timer and real time clock of the controller.
The KB 240 / 400 / 720 (E6) chambers are equipped with a door heating.
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 an Ethernet interface for computer communication, e.g. via the com-
munication software APT-COM™ 3 DataControlSystem (option, chap. 19.1). For further options, see
chap. 23.5.
The KB 240 / 400 / 720 (E6) chambers are equipped with four castors. Both front castors can be easily
locked via the attached brakes.
Temperature range at ambient temperature of 25 °C / 77 °F: -5 °C / 23 °F up to +100 °C / 212 °F
