Reliable temperature and humidity chambers With LCD Touch Panel
Walk-in application
A KOMEG Walk-In Chamber serves as a test site for large components,
assemblies, and finished products. KOMEG manufactures both Panel
Walk-In Chambers and Solid Walk-In Chambers and can be configured
as a temperature chamber or a temperature humidity chamber.
Standard Met and Implemented:
GB/Bb T2423.2-89 high temperature test method
GB2423.1-89 test A: low temperature test method 6
GJB150.4-1986 test at low temperature
IEC60068-2-1 low temperature test method
IEC60068-2-38 temperature cycle
IEC60068-2-78 constant humidity temperature
1. Advantages:
Structure:
Our housing are high-quality carbon steel with static color spray outside and galvanized steel sheet inside. Sheet metal processing
machines are from Germany. Trumph is famous for its precise bending
technology, so our products outlook looks quality, precise and
neat.
Refrigerating System:
We use tube bending machine for copper tube bending, this way can
decrease the welding points. This is easy to keep the copper tube
clean to ensure longer service life of the compressor. Also less
welding points can reduce the resistance when the liquid flowing
inside, to keep compressor working in higher efficiency, and better
energy-saving.
Water and electricity system separating design:
For improving the comparable fragile part, heating part of constant
high damp heat test, we apply water and electricity system
separating design, to keep the water and electricity system
separated with external humidifying system, and use top brand(e.g.:
DANFOSS, Schneider, Danfoss, Emerson, Saginomiya, etc. ) for all
electronic components to make sure the chambers’ quality and
service time.
3. High temperature limits of test chambers
There are many types of test chambers, but they all high and low
temperature limits. Let's take a look at the typical high
temperatures thresholds and why they exist.
Test chambers usually have wire heaters made of a material called
Nichrome. By placing successive loops of heater wire, a greater
amount of heat that is generated. The result looks a lot like the
inside of a toaster. Fans circulate the air past the heaters, so
the samples in the chamber are not exposed to radiant heat. It is
very easy to add heaters and increase the speed and / or high limit
of a chamber.
KOMEG chambers typically have a high temperature limits under
200°C. Here is a break-down of why a chamber's high temperature
limit exists:
150°C: There are two reasons we may limit a chamber to 150°C. First,
there may be a limitation of the materials used inside the chamber.
Secondly, for extremely fast chambers, we may limit the high
temperature to avoid problems with accidentally tripping overheat
protection devices.
170-180°C: Most models stop at this temperature range. There is a risk
of burning the oil inside the refrigeration's cooling coil.

5. Temperature and Humidity Test Capabilities
KOMEG have a variety of temperature and humidity chambers from
small to walk-in chambers that can reproduce a wide range of
climatic conditions incluiding high and low temperature as
well as combined temperature and humidity conditions. KOMEG also
support a climatic test facility dedicated to tests against
requirements for telecoms and radio products.
