A high-temperature test chamber is an essential instrument for evaluating the reliability of industrial products under extreme heat conditions. It tests various performance metrics of products exposed to high and low-temperature transitions.

During the operation of a temperature and humidity test chamber, some abnormal situations may occur, such as excessive overheating of the condenser tube.

During the past twelve months, several third-party testing bodies and OEM laboratories reported the same problem: when running dust tests in accordance with GB/T 4208, IEC 60529 or MIL-STD-810, the batch cycle has stretched from 48 h to 72 h, even 96 h, while energy consumption has risen by more than 30 %.

Frost formation in a thermal shock test chamber is a sublimation phenomenon where moisture inside the chamber condenses under low-temperature conditions. But why does this happen? Is it simply because the chamber temperature is too low?

Some customers report that their sand and dust test chambers are not operating efficiently and have reached a bottleneck.
