Performance test system HETS-ALK-S

for electrolyserson siteautomatic

Product overview
HETS-ALK-S series provides a precise, reliable and convenient testing platform for hydrogen production using ALK electrolyzers. The system is composed of a gas–liquid separation unit, gas concentration detection unit, gas purification/cooling/drying module, water-thermal management module, pressure interlock control module, measurement & control unit and safety protection module. Online data monitoring and processing allow analysis of the tested electrolyzer's performance, lifetime, reliability and safety. The system is suitable for ALK electrolyzer R&D, validation and end-of-line testing.
