RS485 Interface Computer Controlled Large Volume Low Temperature Test Chamber
1. High-Low Temperature Chamber
Extreme temperatures are the leading cause of failure in almost all types of equipment. Our computer controlled chambers can produce constant or cyclic temperatures ranging from -70C / -158 F to +180C / 356 F. Multiple walk-in chambers as well as numerous smaller chambers allow for flexibility to meet any schedule. Our walk-in chambers can be easily expanded to accommodate almost any size product. Automated thermal shock testing is also available.

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.
