Centralized inventory by Domex-E
reducing burden, improving efficiency

Critical spare parts for large turbomachinery units are high in value and long in lead time. Traditional per-unit stocking often means heavy inventory investment with limited risk coverage. When equipment fails, procurement can take 6–10 months.

Domex-E operates a centralized spare parts center stocking key components, wear parts, and instrumentation for the full STC-GC / STC-GV / STC-GV-H series and ALT expanders—offering customers a more flexible service model.

Standing inventory with dispatch within 24 hours; OEM and locally-sourced critical parts in parallel—helping customers reduce inventory pressure and downtime risk.
