Your certified partner for large-engine applications with worldwide know-how

High-speed engines

High-speed engines are used as gensets in CHP plants, in ships, and often in standard containers. As a development partner, HYDAC is on hand to help you and can offer all-inclusive diesel conditioning: from dewatering the day tank to cleaning the fuel in filters located at the engine.

Medium-speed engines

As they can be started up quickly and frequently, medium-speed engines are used in decentralised power plants. The distinctive feature of these engines is their provision of a control reserve. Their high efficiency and low emissions also support the transition to alternative energy. Work with HYDAC to optimise your fuel and lubrication oil systems for efficient and sustainable operation.

Low-speed engines

Low-speed engines provide the energy needed to power large transport ships. For these engines which work according to the 2-stroke principle, fluid conditioning is a key focus. HYDAC takes care of efficient cleaning and dewatering of your operating fluids for reliable and environmentally friendly use under extreme conditions. We can help you to save investment costs and service costs.

Sustainability & standardisation

Never lose sight of efficient and safe operation of your large engine – we work with you to optimise your system and find the custom solution for you. Use the potential of standardisation: retrofitting with optimised components and systems can help you to achieve long-term savings in lubrication oil conditioning and fuel treatment.
