HFC-23 Refrigerant 800L High and Low Temperature Recycling Test Chamber for ESS
1. Brief Introduction of ESS:
The objective of Environmental Stress Screening is to tailor a screen which will precipitate and detect latent defects as early as possible in the manufacturing cycle, where it is the most cost effective to correct.
ESS is a process, and it must be controlled. Without control, repeatability, and reliability, the screen would be questionable. The dynamic and thermal profiles for establishing an ESS process are not rigid rules. They are only guidelines.
2. Explore High-low temperature test chambers:
High and low extremes of temperature can significantly alter the mechanical and electrical properties of a product, such as the brittleness of components, viscosity of lubricants, electrical conductivity and oscillator frequencies. TRaC's temperature testing can simulate temperature extremes cycling from -70°C to +180°C (and up to +500°C constant), and KOMEG's 15 temperature chambers cater for small components in our series of 0.4 m3 cabinets through to complete systems, in our range of walk-in chambers.

4. 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.
