Environmental test chamber
 

Functions and support areas
    The environmental test chamber can carry out various environmental simulation tests related to temperature and humidity, such as thermal aging tests, thermal shock test, thermal cycle tests , etc. It is mostly used for the accelerated thermal aging of non-metal materials of nuclear safety-related equipment or the simulation of various operating conditions of nuclear power plants and environmental changes in the processes including equipment transportation and storage , etc. Wherein, one set of equipment can realize the temperature rise rate of 23℃/min in the temperature range of -40℃→180℃.
