1.7 Operating instructions
Depending on the application and location of the chamber, the operator of the alternating climate chamber
must provide the relevant information for safe operation of the chamber in a set of operating instructions.
Keep these operating instructions with the chamber at all times in a place where they are
clearly visible. They must be comprehensible and written in the language of the employees.
1.8 Measures to prevent accidents
The operator of the chamber must observe the following rule: “Betreiben von Arbeitsmitteln. Betreiben von
Kälteanlagen, Wärmepumpen und Kühleinrichtungen“ (Operation of work equipment. Operation of refrig-
eration systems, heat pumps and refrigeration equipment) (GUV-R 500 chap. 2.35) (for Germany).
The manufacturer took the following measures to prevent ignition and explosions:
•Indications on the type plate
See operating manual chap. 1.4.
•Operating manual
An operating manual is available for each chamber.
•Overtemperature monitoring
The chamber is equipped with a temperature display, which can be read from outs.
The chamber is equipped with an additional safety controller (temperature safety device class 2 acc. to
DIN 12880:2007). Visual and audible (buzzer) signals indicate temperature exceeding.
•Safety, measurement, and control equipment
The safety, measuring, and control equipment is easily accessible.
•Electrostatic charge
The interior parts are grounded.
•Non-ionizing radiation
Non-ionizing radiation is not intentionally produced, but released only for technical reasons by electrical
equipment (e.g. electric motors, power cables, solenoids). The machine has no permanent magnets. If
persons with active implants (e.g. pacemakers, defibrillators) keep a safe distance (distance of field
source to implant) of 30 cm, an influence of these implants can be excluded with high probability.
•Protection against touchable surfaces
Tested according to EN ISO 13732-1:2008.
•Floors
See operating manual chap. 3.4 for correct installation
•Cleaning
See operating manual chap. 21.2.
•Examinations
The chamber has been inspected by the “Deutsche Gesetzliche Unfallversicherung e.V. (DGUV)
(German Social Accident Insurance (DGUV)” (German Social Accident Insurance (DGUV), Testing
and Certification Body for Foodstuffs and Packaging Industry in DGUV Test) and bears the GS mark.

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 sys-
tem permitting rapid cooling-down speeds. In addition, it provides almost unlimited possibilities for adapta-
tion 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 discol-
oration of the metallic surfaces (yellowish-brown or blue) by natural oxidation processes. These colora-
tions 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.
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 dis-
play 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.
