Air-cooled standard high-low temperature test chamber for auto electronics parts

1.  KOMEG Climatic Test Chambers Features:

1. The separation of humidifier circuit from electric circuit improves safety and protects the circuit against the leakage of water supply line.

2. Chinese and English optional, LCD touch screen, full color, easy operation and program, high accuracy of 0.1C or 1%R.H.

3. Able to display the relative date and information of the whole operating system in running mode, graphic display, precautions, maintenance and troubleshooting appear on the screen instantly.

4. The Sirocco fan motor provides greater cyclic airflow to avoid dead corner in the chamber so as to obtain high temperature and humidity uniformity.

5. The system of heating up, heating down, dehumidifying, and humidifying can be operated independently so as to reduce the cost of testing, extend the operation life of the machine and decrease the failure rate.

2. 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.
