1.6 Intended use
Alternating climate chambers series MKF / MKFT are suitable for temperature drying and heat treatment
of solid or pulverized charging material, as well as bulk material, using the supply of heat. They are suita-
ble for harmless materials. A mixture of any component of the charging material with air must NOT be
explosive. The operating temperature must lie below the flash point or below the sublimation point of the
charging material. Any component of the charging material must NOT be able to release toxic gases.
Other applications are not approved.
The chambers are specially designed for solving all the problems which occur during material and ageing
tests.
The chambers are not classified as medical devices as defined by the Medical Device Directive
93/42/EEC.
Due to the special demands of the Medical Device Directive (MDD), these ovens are not quali-
fied for sterilization of medical devices as defined by the directive 93/42/EWG.
Following the instructions in this operating manual and conducting regular maintenance work
(chap. 17) is part of the intended use.
The chambers do not dispose of any measures of explosion protection.
DANGER
Explosion or implosion hazard.
Danger of poisoning.
Danger of death.
∅Do NOT introduce any substance combustible or explosive at working temperature into
the chamber, in particular no energy sources such as batteries or lithium-ion batteries
∅NO explosive dust or air-solvent mixture in the inner chamber.
∅Do NOT introduce any substance which could lead to release of toxic gases.
The charging material shall not contain any corrosive ingredients that may damage the ma-
chine components made of stainless steel, aluminum, and copper. Such ingredients include in
particular acids and halides. Any corrosive damage caused by such ingredients is excluded
from liability by BINDER GmbH.
In case of foreseeable use of the chamber there is no risk for the user through the integration of the
chamber into systems or by special environmental or operating conditions in the sense of EN 61010-
1:2010. For this, the intended use of the chamber and all its connections must be observed.
1.7 Operating instructions
Depending on the application and location of the chamber, the operator of the 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.

MKF+ MKFT (E3.2) 07/2017 page 13/115
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
refrigeration 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 outside.
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 electri-
cal equipment (e.g. electric motors, power cables, solenoids). The machine has no permanent mag-
nets. 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. 17.2.
•Examinations
The chamber has been inspected by the “Deutsche Gesetzliche Unfallversicherung e.V. (DGUV)

These values are to be considered only as approximate values. The sensor resistance largely de-
pends on the temperature and humidity conditions during the time of exposure to harmful substances.
Avoid simultaneous condensation. Tolerated error of measurement: ± 2 % r.H. The maximum work
place threshold limit value is the one that can be regarded as harmless for humans.
•Vapors of oil and fat are dangerous for the sensor because they may condensate at the sensor and
thus prevent its function (insulating layer). For similar reasons it is not possible to measure smoke
gases.

2. Chamber description
The alternating climate chamber MKF / MKFT 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 prob-
lems which occur during material as well as ageing and stress tests.
The chambers are equipped with a multifunctional microprocessor display controller with 2-channel tech-
nology 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 program controller MB1 permits the
high precision performance of temperature and humidity cycles with rapid heating up and cooling down
phases.
With its microprocessor controlled humidifying and dehumidifying system the chamber is a high-precision
climatic test chamber. It covers the regular test specifications for temperature and climates corresponding
to DIN und IEC standards. Furthermore, it permits simulating exactly and over long periods constant con-
ditions for other applications such as sample conditioning for material testing of paper, textiles, plastics,
building materials, etc.
The patented APT.line™ preheating chamber and air conduction technology guarantees excellent spatial
temperature and humidity values for the total working area. The chamber provides a powerful refrigerat-
ing system with rapid cooling-down speeds. In addition, the chamber provides almost unlimited possibili-
ties for adaptation to individual customer requirements based upon extensive programming options.
A resistance humidifying system humidifies the air. For this purpose, use deionized (demineralized) wa-
ter. The option BINDER Pure Aqua Service permits using the chamber with any degree of water hard-
ness.
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 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 color-display con-
troller MB1 and is also possible directly with a computer via Intranet in connection with the communication
software APT-COM™ 3 DataControlSystem (option, chap. 16.1). The chamber comes equipped with an
Ethernet serial interface for computer communication. In addition, the BINDER communication software
APT-COM (option) permits networking up to 30 chambers and connecting them to a PC for controlling
and programming, as well as recording and representing temperature and humidity data. For further op-
tions, see chap. 20.6.
The chambers are equipped with four castors. Both front castors can be easily locked via the attached
brakes.
