Desalination AOG & Plant-Down Emergency Sourcing

Siemens Drive Failure
Genuine Control Parts, 4-Hour Response

Siemens SINAMICS drives control every high-pressure feed pump in your SWRO plant. When a VFD fails, the pump either runs fixed-speed — risking membrane damage — or shuts down entirely. Alisios sources genuine Siemens parts through authorized distributors and responds in 4 hours.

Why Siemens Drive Failures Are AOG Events

Siemens SINAMICS VFDs control high-pressure feed pumps; SIMATIC PLCs manage plant logic; Siemens switchgear distributes power. When a VFD fails, most operators shut down the SWRO train rather than risk membrane damage from uncontrolled speed operation. Same-day sourcing is required.

Frequently Asked Questions

Which Siemens products does Alisios source for desalination?

SINAMICS G120, G150 and S150 drives, SIMATIC S7-300/400/1500 modules, SIMATIC HMI panels, SENTRON circuit breakers and SIVACON MCC components.

Can the SWRO plant run without the Siemens VFD?

Most plants can bypass to DOL fixed-speed, but this risks membrane overpressure. Most operators shut down the train rather than risk membrane damage.

Does Alisios source legacy Siemens components?

Yes. S7-300 and S7-400 hardware for pre-2015 plants is among our most common desalination requests. We source authorized new-old-stock and factory-refurbished units.

What information is needed?

Company/plant name, Siemens part number or product designation, quantity, destination, and whether the plant is currently down.
