Air system
Marine turbocharger parts, nozzle rings and charge air coolers
A turbocharger that loses efficiency quietly costs you fuel on every running hour. We supply rotor assemblies, nozzle rings, blades, bearing and seal kits, plus charge air coolers and scavenge air parts.
- Single unit or complete kit
- OEM and verified alternatives
- Certificate with shipment
- Quotation in one business day
Components
What we supply
Turbocharger wear is gradual, so it is usually found late. The parts that fail first are the nozzle ring, the turbine blade tips and the bearing and seal kit. We can quote the wear parts on their own, or a complete rotor assembly if the shaft and wheels are beyond reconditioning.
| Component | Function | Supply notes |
|---|---|---|
| Turbocharger rotor assembly | Complete shaft with turbine and compressor wheels | Balanced assembly, ready to fit |
| Nozzle ring | Directs exhaust gas onto the turbine blades | Common wear item, several vane angles |
| Turbine blades | Extract energy from exhaust gas | Supplied as a set or individually |
| Compressor wheel | Compresses scavenge air | Aluminium or titanium depending on type |
| Bearing & seal kit | Supports the rotor, keeps oil in place | Full kit with O-rings and thrust bearings |
| Charge air cooler | Cools air after compression | Plate or tube bundle, core replacement |
| Scavenge air receiver | Stores air for cylinder scavenging | Inspection covers and gaskets |

Questions
Before you enquire
Can you supply the nozzle ring only?
Yes, and it is the most common single-part turbocharger enquiry. Send the turbocharger type and frame size, and the engine rating if you have it, because the vane angle changes with rating.
Is a rotor assembly balanced before delivery?
Rotor assemblies ship with a dynamic balance report. If you are reusing your own shaft with new blades, have it rebalanced locally — fitting unbalanced blades is what destroys the bearing kit.
Do you supply charge air cooler cores or complete units?
Both. On most engines a core and gasket set is enough and costs a fraction of a complete cooler. Where the housing is corroded, we quote the complete unit.
