Auxiliary systems for Wärtsilä engines

You can ensure maximum compatibility when you choose the auxiliary systems to be delivered together with the main propulsion engines and diesel generator sets.

Auxiliary systems for your Wärtsilä engines

Maximum compatibility is ensured when auxiliary systems are delivered together with the main propulsion engines and diesel generator sets. Whenever necessary, the auxiliary systems are tailored to optimise the operating performance for a specific trade. The systems are specified to minimise building costs and operating costs for a specific combination of main and auxiliary engines. Tailor-made modular auxiliary units are available on request.

Standardised Modular Auxiliary Units

Fuel oil booster
Fuel oil separating
Lubricating oil separating
Cooling water preheating
Starting air compressors
Oil mist separator
Oily water bilge separator

Some equipment can be built on the engine, and the rest can be delivered separately or grouped in modules. Depending on the engine type and application, lubricating oil pump, HT- and LT-cooling water pumps, fuel pump, oil filters and coolers, pre-lubricating oil pump and thermostatic valves can be built on the engine. Stand-by pumps, seawater pumps, central coolers, starting air vessels, lubricating oil automatic filters, exhaust gas silencers and boilers are typically delivered for separate mounting.
