ETZ Series – PEM Electrolyzer System
The ETZ series PEM water electrolysis hydrogen production system can achieve a hydrogen output of up to 500 Nm³/h per unit. It integrates a PEM electrolyzer, gas-liquid separation system, hydrogen purification unit, rectifier power supply system, and cooling system. With advantages such as fast response, high efficiency, and the ability to operate at high pressure. It offers flexibility and applicability for green hydrogen production.
Product Applications
Hydrogen Energy Transportation Sector: On-site hydrogen production at refueling stations, replacing traditional long-distance hydrogen transport; small integrated hydrogen production and refueling units suitable for short-distance mobility scenarios in communities, industrial parks, schools, etc.; hydrogen drones and hydrogen two-wheelers paired with distributed green hydrogen production to meet fast refueling needs.
Industrial and Chemical Sector: Provides high-purity hydrogen for oil refining, chemical, electronics manufacturing, and other industries; replaces conventional grey hydrogen to promote low-carbon transformation in the industrial sector; suitable for applications requiring high hydrogen purity (e.g., hydrogen for fuel cells).
Wind-Solar-Hydrogen Integrated Projects: Works with fluctuating power sources such as photovoltaics and wind power to enable local consumption of renewable energy; supports integrated 'production-storage-refueling' deployment; suitable for remote areas and off-grid projects.
Research and Demonstration Projects: Teaching and experimental platforms for universities and research institutions; core equipment for national hydrogen energy demonstration zones and demonstration refueling stations; basic platform for PEM technology validation and engineering application.
