Turbocharger service general

The Turbocharger is a very important piece of equipment and a necessity to keep your engine running. This is why most shipowners tends to offer large amounts of money to buy new equipment once a breakdown occurs.


The good news is that new is not necessarily best!

A turbocharger with a wear and/or damage can in most cases be repaired at a price up to 75% less than buying a new one. It can even improve life cycles compared to new components from the manufacturer – and with even better delivery times.

Availability and fast response are key to mutual success and at the same time we can offer to repair parts which often would be stated as non-repairable. Common problems can most likely be repaired in our workshop – and along comes always a 24-month liability for defects and shortages.



Our Turbocharger Service includes:

    • Cartridge Overhauls
    • Turbine Blade Repair
    • Nozzle Ring Repair
    • Balancing Facilities
    • Parts Supply
    • Field Service

In our workshop in Copenhagen, we have a team of factory trained service engineers working around the clock to service our customers.


We are here to help so do not hesitate to contact us. For emergencies please call right away – we are here 24/7


About HS Turbochargers

All rotating parts in the HS Turbochargers can be replaced separately and are individually balanced. The turbine wheels are Axial, the design is compact and the weight relatively low for fast response performance.


Hedemora Turbocharger Types

The internal plain bearings use lubrication oil from the engine and are designed for a better access to the turbine wheel and to the compressor – and therefor allows for a smaller design.
