Performance test system HETS-PWE-S

for electrolyserson siteautomatic

Product overview
HETS-PWE-S series provides a precise, reliable and convenient test platform for PEM electrolyzers. The system consists of a gas-liquid separation unit, gas concentration monitoring unit, gas cooling and drying module, water/thermal management module, pressure interlock control module, measurement & control unit and safety module. By online data monitoring and processing on the test platform, it analyses the tested electrolyzer's performance, lifetime, reliability and safety. Suitable for R&D, qualification and end-of-line testing of PEM electrolyzers.
