Walk-In Temperature Test Chambersr with Three levels of overheat protection
Walk-In Temperature Test Chambers
The KOEMG KMHW-Series offers superior strength and durability.
INSTRUMENTATION AND CONTROL
Operation of the MAP is controlled by the KOMEG KM-5166 touch-screen controller.
The controller is installed in a console that can be installed next to the chamber door for easy access.
Instrumentation features:
Three levels of overheat protection
Running time meter
Audible alarm
USB upload / download test profls and data
Event relays for interfacing with additional test equipment
Digial programmable control systems include a ‘specimen power’ relay which should
be used to interlock any powered test samples with the chamber.
In the event of a chamber alarm or shut-down, the samples will also be turned off.
Otherwise damage may occur because the chamber will heat-up due to the samples running.

KOMEG Temperature Humidity Test Chamber Features:
The refrigerating system is the core/heart part of the test chamber.
For enhance the whole refrigerating system performance, we use professional and advanced copper tube bending machine, this can decrease the welding points over 50%, and decrease right-angles of the tube, Also less welding points can reduce the resistance when the liquid flowing inside, to keep compressor working in higher efficiency, and better energy-saving.
And for welding the copper tube, we use Liquid Nitrogen protection welding technology, this can better protect the tube and keep the cooling system clean.
All this will do good to the compressor.
We use GEA Bock semi-hermetic compressor. According to our over 20 years experiences in this climatic test chambers field, GEA Bock Compressor has excellent performance in refrigerating effect and running stability; has good noise control, also energy-saving.
