Our Offering: Retrofits, Overhauls, and Exchange Cartridges for Turbochargers
Take advantage of our extensive turbocharger services. We service turbochargers from any engine manufacturer, including all turbochargers for Cat and MaK engines.

Retrofits – Restoring your turbochargers to peak performance
Looking to retrofit your engine with a turbocharger to boost performance or meet emission limits and standards? We meticulously plan our retrofits to guarantee compliance with safety standards and regulations. The turbocharger is tailored to your engine’s specific needs and operational profile, ensuring seamless integration into the overall system.
In maritime applications, we recognize the need for components to be exceptionally corrosion-resistant, long-lasting, and robust. Therefore, we exclusively use premium original spare parts.
When does the overhaul need to be scheduled?
Regular overhauls of turbochargers are essential to maintain dependable engine performance. These overhauls are generally included in the maintenance plan and are typically performed after 12,000 operating hours.
If, however, the engine experiences a drop in performance or deviations in key parameters before reaching the planned hours, this could signal damage due to wear or foreign objects. In these cases, the turbocharger overhaul should be done earlier than the standard service interval.
Here’s how the service works
During a turbocharger overhaul, we begin by disassembling the unit and conducting a detailed inspection of all components to detect signs of wear or damage. Following a comprehensive cleaning to eliminate deposits, dirt, and oil residues, we replace wear parts such as bearings and seals. We also inspect the turbine and compressor wheels and balance the rotors as needed. After all parts are overhauled, the turbocharger is reassembled, tested, and calibrated.

Boosting Marine Power: The Importance of Turbochargers in the Maritime Industry
Turbochargers are essential in the maritime industry as they help enhance the performance and efficiency of ship engines. These engines, often powering large vessels, require immense force to move through the water. Turbochargers play a key role by optimizing engine performance.
Efficient combustion through exhaust turbocharging
In marine applications, turbochargers are used to increase the air supply to ship engines. They operate on the principle of exhaust turbocharging: the engine's exhaust gases are directed through the turbocharger, driving a turbine rotor. This rotor is connected via a shaft to a compressor rotor, which draws in and compresses fresh air. Compressing the air increases its density in the cylinder, leading to more efficient fuel combustion.
The enhanced combustion efficiency improves engine performance while simultaneously reducing fuel consumption and emissions. This is particularly crucial in the maritime industry, which is increasingly seeking eco-friendly and efficient solutions to operate more sustainably and meet stricter environmental regulations.
Moreover, turbochargers offer the flexibility to boost engine performance when needed, such as in situations requiring higher speeds or additional energy for specific applications.
Overall, turbochargers are vital for marine applications to maximize engine performance, optimize fuel consumption, reduce emissions, and improve the environmental compatibility of ship propulsion systems.
