2. Chamber description
The constant climate chambers KBF-S are equipped with a multifunctional microprocessor display con-
troller 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 microprocessor controlled humidifying and dehumidifying system the KBF-S is a high-precision
constant climate chamber.
The KBF-S meets the “Long term testing” and “Accelerated testing” requirements for climatic chambers
acc. to ICH guideline CPMP/ICH/2736/99 (Q1A).
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.
Freshwater is supplied by manually filling a freshwater can which shall be placed inside the supplied
standard water can support. In addition a magnetic support adjustable in height is optionally available.
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 at-
tainment and maintenance of the desired temperature accuracy.
A resistance humidifying system humidifies the air. For this purpose, use deionized (demineralized) wa-
ter. The option BINDER Pure Aqua Service allows using the chamber with any degree of water hardness.
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.
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 efficient RD4 chamber controller is equipped with a multitude of operating functions, in addition to
recorder and alarm functions. Set-point entry is easily accomplished directly via the chamber controller
and is also possible directly with a computer via Intranet in connection with the communication software
APT-COM™ 3 DataControlSystem (option, chap. 20.1). The constant climate chamber comes equipped
with an Ethernet serial interface for computer communication and with a USB interface. In addition, the
BINDER communication software APT-COM™ 3 permits networking up to 40 chambers and connecting
them to a PC for controlling and programming, as well as recording and representing temperature and
humidity data. For further options, see chap.24.5.
The chambers size 240 and 720 are equipped with four castors. Both front castors can be easily locked
via the attached brakes.
Temperature range: 0 °C / 32 °F up to 70 °C / 158 °F , humidity range: 10% r.h. to 80% r.h.
For the control ranges of temperature and humidity, see climatic diagrams (chap. 18).
