System Scope & Process Architecture
The H-Series integrates the core PEM stack with necessary balance-of-plant (BoP) modules into a unified skid-mounted architecture, engineered for stable mid-range hydrogen production.
PEM Stack Core
The electrochemical heart where purified water is converted into hydrogen and oxygen gases under DC power.
Water & Thermal Management
Circulation, filtration, and conductivity monitoring of DI water, coupled with heat exchangers to maintain optimal operating temperatures.
Gas-Liquid Separation
Vessels and liquid-level controls designed to efficiently separate hydrogen and oxygen gases from the circulating water stream.
Power Supply & Rectifier
Converts AC grid or renewable input into stable, controllable DC power required for the electrolysis process.
Utilities & Project Interfaces
Customize the H-Series around your specific on-site hydrogen project requirements. Review utility boundaries to ensure seamless integration.
Hydrogen Output Review
Confirm required Nm³/h, daily hydrogen demand, operating hours, and peak hydrogen demand profiles.
Purity & Gas Treatment
Review hydrogen purity targets, drying, purification, gas-liquid separation, and downstream use cases.
Outlet Pressure Match
Align system outlet pressure to storage, compressor, fuel cell, microgrid, or specific process requirements.
Skid Layout Configuration
Configure skid-mounted layout according to installation space, operation access, utility connections, and maintenance.
Power & Cooling Match
Review grid or renewable power inputs, rectifier sizing, cooling methods (water/chiller), and ambient conditions.
Control & Safety Integration
Define PLC, HMI, alarm limits, hydrogen detection, shutdown logic, and project-specific automation interfaces.
Controls, Operating Range & Safety
