HIU TECH / TECHNICAL SCOPE01—03
Component-level repair
Where a fault is proven within the unit, the repair scope can address valves, actuators, pumps, sensors, controls, heat exchangers and associated hydraulic components.
Verification after repair
Operation is tested under demand and recorded. The objective is not simply to clear a symptom, but to restore stable controlled performance.
