Configuration review
Four Decisions to Settle Before Ordering
The required hydrogen duty, delivery condition, site interfaces and acceptance method should be described on the same quotation basis.
Electrical integration
Provide grid or renewable-power characteristics, rectifier boundary and control philosophy.
Balance of plant
Define water treatment, gas conditioning, cooling, ventilation, safety and downstream delivery ownership.
Factory and site tests
Agree FAT conditions, interface checks, documentation and any site acceptance or commissioning scope.
MODULAR EXPANSION & PROJECT LAYOUT
Engineering the M-Series for Higher-Capacity Hydrogen Projects
The M-Series is intended for projects where hydrogen capacity, equipment layout, power conversion, cooling, gas handling and future expansion need to be reviewed as one modular system. Final skid quantity and equipment arrangement should be confirmed according to the required production rate, operating profile, site utilities, maintenance access and expansion plan.
Modular Output
Designed for 10–50 Nm³/h hydrogen production where stable, scalable output is required.
Multi-Skid Layout
Suitable for projects requiring modular equipment arrangement, phased expansion, and service access.
Renewable Integration
Engineered to couple with solar, wind, hybrid grids, or dedicated power-to-gas infrastructure.
BoP Integration
Water, power, cooling, gas handling, and safety controls reviewed as one unified system boundary.
System Scope & Process Architecture
The PEM stack is the electrochemical core, but an M-Series system requires modular stack grouping, skid layout, precision power supply, water treatment, gas-liquid separation, cooling, and safety protection for stable operation.
