2. Chamber description
The constant climate chambers KBF / KBF-UL and KMF are equipped with a multifunctional microprocessor
display controller with 2-channel technology for temperature and humidity plus a digital display accurate to
one-tenth of a degree resp. 0.1% r.h. With its comprehensive program control functions, the display pro-
gram controller MB2 permits the high precision performance of temperature and humidity cycles.
With its microprocessor-controlled humidifying and dehumidifying system the chamber is a high-precision
constant climate chamber.
The KBF / KBF-UL completely meets the requirements for climatic chambers of the stipulated stability and
durability tests for pharmaceutical products: Stability tests acc. to ICH guideline CPMP/ICH/2736/99 (Q1A)
The KMF completely meets the requirements of the stipulated stability and durability tests for industrial
products.
Furthermore, it permits simulating exactly and over long periods constant conditions for other applications
such as sample conditioning for material testing of paper, textiles, plastics, building materials, etc.
The APT.line™ preheating chamber system guarantees high level of spatial and time-based temperature
precision, thanks to the direct and distributed air circulation into the interior. The fan supports exact attain-
ment and maintenance of the desired temperature accuracy.
Humidity control: A resistance humidifying system humidifies the air. For this purpose, use deionized
(demineralized) water. The option BINDER Pure Aqua Service allows using the chamber with any degree
of water hardness.
Material: 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 pow-
der-coated. All corners and edges are also completely coated.
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.
Controller: The efficient program controller is equipped with a multitude of operating functions, in addition
to recorder and alarm functions. Programming of test cycles is easily accomplished via the modern MB2
touch screen controller and is also possible directly with a computer via Intranet in connection with the APT-
COM™ 4 Multi Management Software (option, chap. 19.1). The chamber comes equipped with an Ethernet
serial interface for computer communication. In addition, the BINDER APT-COM™ 4 Multi Management
Software permits networking up to 100 chambers and connecting them to a PC for controlling and program-
ming, as well as recording and representing temperature and humidity data. For further options, see
chap.23.6.
The chambers size 240, 720, and 1020 are equipped with four castors. Both front castors can be easily
locked via the attached brakes.
KBF / KBF-UL: temperature range: 0 °C / 32 °F up to 70 °C / 158 °F, humidity range: 10% r.h. to 80% r.h.
KMF: temperature range -10 °C / 14 °F up to +100 °C / 212 °F, humidity range: 10 % r.h. to 98 % r.h.
For the control ranges of temperature and humidity, see climatic diagrams (chap. 17).
