Turbogenerators

Dedicated to meeting your needs

Generators are critical to your power production. With complete in-house capabilities for the total overhaul, upgrade or repair of generators, not only does Sulzer service your equipment but we also reengineer replacement parts to resolve repetitive failures and problems. Sulzer offers unique services to make your generators run safely and reliably. Our engineers are recognized for their dedication to reliably meeting your needs.

We repair, overhaul, and upgrade turbogenerators

We have experts in generator repair and remanufacturing at our locations around the globe. Our capability and experience cover machines of all sizes, providing rotor rewinds from the smallest anywhere from 2 to 48 poles up to 500 MVA.

We can use condition monitoring to support the life cycle management of your generator. Our in-house coil manufacturing facility minimizes outage times and maximizes generator efficiency and on older units, we can perform an upgrade with the latest insulation systems to enable more flexible operation.These gains are possible because our coils are designed, manufactured and tested in-house.
