01 / What We Fabricate
The Mechanical Platform Around Electrolyzer Equipment
An electrolyzer enclosure supports process modules, electrical cabinets, ventilation openings, access doors and maintenance zones inside one coordinated structure. DRAmetal manufactures the mechanical housing to the OEM's released drawings; hydrogen process design and safety validation remain outside our fabrication scope.
External Panel Systems
Doors, roofs, removable panels and service covers with controlled gaps, hardware and finish.
Internal Mechanical Supports
Mounting plates, trays, cable supports, partitions and brackets for OEM-installed system components.
Safety-System Interfaces
Drawing-defined ventilation, sensor, drain and emergency-access openings fabricated for the OEM's validated system design.
Our scope: the fabricated enclosure, frame and specified mechanical subassemblies
DRAmetal does not design or certify electrolyzer stacks, hydrogen piping, pressure systems, ventilation capacity, gas detection, hazardous-area equipment or functional safety. The system OEM owns hazard analysis, ISO 22734 or other applicable compliance, validation and final approval.
02 / Electrolyzer Enclosure Formats
Mechanical Housings for Green Hydrogen Systems
The supply boundary can range from a compact cabinet to a large modular housing. Every format is built to customer drawings rather than represented as a complete hydrogen system.
Compact Compact Electrolyzer Cabinets
Floor-standing cabinets for laboratory, pilot and distributed electrolyzer equipment with coordinated service access and module supports.
- Structure Cabinet / welded base
- Access Front / rear panels
- Scope Mechanical housing
Skid Skid-Mounted Enclosures
Panelized housings around OEM process skids with removable service zones, lifting interfaces and transport-ready structures.
- Base Welded skid frame
- Panels Fixed / removable
- Control Module datums
Containerized Containerized Electrolyzer Housings
Large outdoor mechanical structures with equipment bays, service doors, roof systems and drawing-defined ventilation interfaces.
- Format Custom / container style
- Environment Project defined
- Packout Module controlled
Power Module Electrolyzer Power Cabinets
Mechanical cabinet structures for rectifier, controls and auxiliary electrical equipment integrated into the OEM enclosure platform.
- Interfaces OEM electrical layout
- Cooling Cutouts specified
- Assembly Hardware ready

04 / Manufacturing Process
From System Layout to Mechanical Enclosure
01
Supply-Boundary Review
Confirm enclosure scope, module loads, structural datums, service zones, lifting, transport and customer-owned safety interfaces.
02
DFM and Fixture Plan
Review frame weld sequence, panel split lines, door geometry, finish allowances and inspection access.
03
First-Article Structure
Build a production-intent frame and panel set, then validate OEM module and service interfaces before release.
04
Frame and Panel Fabrication
Fixture-weld bases and supports while producing panels, doors, partitions and internal sheet metal in controlled routes.
05
Finish and Mechanical Fit
Apply approved finishes, install specified hardware and verify doors, panels, partitions and mounting interfaces.
06
Configuration Packout
Release structures and loose kits by system model, module zone, serial or lot and drawing revision.
05 / Why It Matters
Why Electrolyzer Housings Need Strict Scope Control
The mechanical enclosure supports a hydrogen-producing system, but fabrication conformity does not prove process or safety performance.
OEM-Owned Hazard Analysis
Ventilation, leak detection, hazardous-area classification and emergency functions must come from the system OEM's validated design.
Stable Module Datums
Stack, piping and power modules depend on controlled mounting planes that must remain accurate after welding and finishing.
Service and Egress Geometry
Doors, removable panels and personnel access must match the released maintenance and emergency-access plan.
Configuration Traceability
Fast-changing hydrogen platforms require controlled models, BOMs, deviations and packout records.

Why Hydrogen Equipment OEMs Choose DRAmetal
01
Frame-and-panel DFM
We review the skid, frame, doors, panels and internal supports as one tolerance-linked assembly.
02
Large-format fabrication
Structural welding, precision sheet metal and hardware-ready assembly are coordinated under one production plan.
03
Mixed-material control
Carbon steel structures and stainless or aluminum internal parts can be routed and protected separately.
04
OEM configuration control
Inspection and packout remain tied to released system model and drawing revision.

09 / FAQ
Hydrogen Electrolyzer Enclosure FAQ
What electrolyzer enclosure parts can DRAmetal manufacture?
We manufacture released mechanical designs including skid bases, welded frames, external panels, doors, partitions, trays, brackets, mounting plates and specified hardware-ready assemblies.
Can you certify an electrolyzer enclosure to ISO 22734 or ATEX?
No certification should be inferred from fabrication alone. The electrolyzer OEM owns system design, hazard assessment, ventilation, gas detection, electrical classification, testing and certification. We manufacture the approved mechanical design and provide agreed fabrication records.
Can you build containerized electrolyzer housings?
Yes, when the customer supplies the controlled structure, load cases, interfaces and validation requirements. We can fabricate custom container-style structures or panelized skid housings within the agreed mechanical scope.
Can enclosure kits be packed by process module?
Yes. Panels, supports and hardware can be identified and packed by system model, module zone, serial or lot, revision and OEM installation sequence.
