Applied in Metal, Plastic, Rubber ?316L Thermal Shock Test Chamber for ESS Testing Process

?

?

ESS is not a test, it is a process

Failures are normal and expected when ESS is applied. This makes ESS radically different than more conventional certification testing which requires failurefree operation as proof of reliability.
?

Thermal Shock Chamber Test is ONE kind of ESS.

1.?Application of thermal shock chamber:?


1.1 Definition:

?

A thermal shock chamber comprising a test area, a high-temperature air conditioning unit having a gas outlet and a gas inlet adjacent to the test area, an outside air supplying unit having an air outlet and an air inlet adjacent to the test area, a low-temperature air conditioning unit having a gas outlet and a gas inlet adjacent to the test area, a first damper assembly for opening the outlet and the inlet of one of the high-temperature air conditioning unit and the outside air supplying unit and closing the outlet and the inlet of the other unit at the same time, and a second damper assembly for opening the outlet and the inlet of one of the low-temperature air conditioning unit and the outside air supplying unit and closing the outlet and the inlet of the other unit at the same time.

1.2 Testing Conditions:

?

This invention relates to a thermal shock chamber for testing various materials, parts of various devices or the like for thermal stress characteristics, durability, thermal strength, etc., for example, by exposing the test sample alternately to two of high-temperature, low-temperature and ambient-temperature atmospheres or successively to these atmospheres in a predetermined order.

?


1.3 KOMEG offers several configurations of thermal shock chambers capable of meeting a wide variety of testing needs.
Vertical, two zone chamber has hot and cold zones that can be controlled independently.
Horizontal, three zone thermal shock chamber utilizes controlled areas for hot, ambient and cold temperatures.
Double duty thermal shock chambers from KOMEG are designed with hot zones above and below the cold zone and a two compartment product carrier that simultaneously moves products between the hot and cold zones.
