2. Chamber description
The alternating climate chamber MK / MKT is a specially developed precision cooling/warming cabinet for
the domain of industrial material testing and environment simulation, with an unrivalled capacity, which far
exceeds the capabilities of normal test cabinets, providing the ideal facilities for solving all the problems
which occur during material as well as ageing and stress tests.
The chambers are equipped with a multifunctional microprocessor display controller for temperature with a
digital display accurate to one-tenth of a degree. With its comprehensive program control functions, the
display program controller MB2 permits the high precision performance of temperature cycles with rapid
heating up and cooling down phases.
The patented APT.line™ preheating chamber and air conduction technology guarantees excellent spatial
temperature values for the total working area. The chamber is equipped with a powerful refrigerating system
permitting rapid cooling-down speeds. In addition, it provides almost unlimited possibilities for adaptation
to individual customer requirements based upon extensive programming options.
The high-quality housing insulation guarantees both a low noise mode of operation and a consistently low
housing temperature. 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). When operating the
chamber at temperatures above 150 °C / 302°F, the impact of the oxygen in the air may cause discoloration
of the metallic surfaces (yellowish-brown or blue) by natural oxidation processes. These colorations are
harmless and will in no way impair the function or quality of the chamber. The housing is RAL 7035 powder-
coated. All corners and edges are also completely coated.
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
touchscreen display controller MB2 and is also possible directly with a computer via Intranet in connection
with the APT-COM™ 4 Multi Management Software (option, chap. 20.1). The chamber comes regularly
equipped with an Ethernet serial interface for computer communication. In addition, the BINDER APT-
COM™ 4 Multi Management Software (option) permits networking up to 100 chambers and connecting
them to a PC for controlling and programming, as well as recording and representing temperature data. For
further options, see chap. 24.6.
The chambers
are equipped with four castors. Both front castors can be easily locked via the attached
brakes.
MK: You can operate the chamber in a temperature range from -40 °C / -40 °F up to +180 ºC / 356 °F.
MKT: You can operate the chamber in a temperature range from -70 °C / -94 °F up to +180 ºC / 356 °F.
