Equipment
Description
1.
Deaerator / Degasser Tanks
Used for removing dissolved oxygen and gases from feed water before electrolysis. These tanks operate under vacuum or low pressure and demand corrosion-resistant construction (SS316L or Duplex). We can fabricate units up to 300 KL with polished interiors and high-efficiency internals.

Equipment
Description
2.
High-Pressure Hydrogen Storage Vessels
Designed to safely store hydrogen gas at pressures of up to 350–700 bar. These vessels require precise fabrication, radiography-quality welds, and compliance with ASME Sec VIII Div 1/2. We offer heavy-wall construction up to 100 mm in carbon steel or stainless steel, as per hydrogen compatibility.
S. No
Equipment
Description
3.
Electrolyzer Skids (Static Part)
These include static balance-of-plant modules like tanks, headers, piping assemblies, and instrument racks that integrate with imported electrolyzer stacks. Our capability allows for modular fabrication with tight tolerance assemblies and full SS construction.
S. No
Equipment
Description
4.
Gas–Liquid Separators (H₂–Water)
Installed downstream of electrolyzers to separate moisture from hydrogen. These vessels require internal baffles and demisters for coalescence separation. We manufacture vertical or horizontal designs with precision nozzles and supports.

S. No
Equipment
Description
5.
Purge Gas/Drain Tanks with Vent Systems
Used to collect vented gases or purged hydrogen for safety. These tanks must handle flammable gas handling, flame arrestors, and vapor vents. We can fabricate these with integrated safety features and corrosion-resistant internals.
S. No
Equipment
Description
6.
Desulfurization Towers
Required when water contains sulfides that would poison electrolyzers. These towers use packed beds or scrubber internals and require acid-proof materials like SS316Ti or FRP lining. We offer cylindrical towers up to 5 m diameter with nozzle and manway customization.
S. No
Equipment
Description
7.
Water Deionizer Columns (Cation/Anion)
Used to supply ultra-pure deionized water for electrolysis. These columns are pressure-rated and require lined or polished interiors to avoid contamination. We fabricate vessels to house mixed-bed resins with internal distributors.
S. No
Equipment
Description
8.
High-Purity Oxygen Vessels
For storage and buffer of by-product oxygen. These vessels must be oxygen-compatible (no oil, no rust) and passivated internally to prevent ignition risk. Our facility ensures clean fabrication and helium leak testing as required.
