Rapid temperature change test chamber features:
1. Intelligent control system, automatically start the large compressor working when fast cooling, high temperature insulation and heating process with a small compressor balance temperature to do linear control, to achieve energy efficiency.
2. Energy saving design, high stability and energy efficiency, saving 30% more than peers one year.
3. Controller using the latest algorithm of fuzzy control technology, automatic adjustment of cold coal flow, and effectively take away the heat load of test samples, so as to achieve the best control effect.
4. Can set different stress screening temperature change rate of 5℃/min、10℃/min、15℃/min、20℃/min.
5.Can perform a rapid temperature change (ESS), condensation test, high temperature and humidity, temperature and humidity cycle test etc...
