Wärtsilä Auxpac 16

The Auxpac 16 is Wärtsilä’s smallest Auxpac generating set and is based on years of experience and our proven technology.


    The Auxpac 16 is available as 5, 6 or 7 cylinder configuration. It comes equipped with a built-in, multi-functional, digital automation system that has an integrated electronic governor to ensure smooth control and fast response to load transients. All Wärtsilä Auxpac generating sets are designed to be installed resiliently to the ship’s hull. The resilient installation method enables easy installation and alignment of the generating set within the vessel. The advantage over conventional mounting methods is that it notably reduces the structure-borne noise transmitted from the generating sets to the ship’s hull, thus improving on-board comfort levels. The resilient installation method also works the other way, protecting a gen-set in stand-by, from harmful vibration originating from the main engine

    Typical application areas
    While the Auxpac 16 has been designed as an auxiliary engine for a variety of vessel types, it is especially suited for providing power to small tankers, bulkers, multi-purpose vessels and small container vessels.

    Operational features
    The Wärtsilä Auxpac 16 is able to operate on different fuels, ranging from the lowest LFO viscosity of 2.0 cSt to an HFO viscosity of 700 cSt (at 50°C). The engine is also able to use low and ultra low sulphur fuel oils (<0.01% S) as per the standards set by authorities for fuel oil used in emission controlled areas.

    Environmental compliance
    The engine is fully compliant with IMO Tier II requirements and, when fitted with exhaust gas after treatment solutions, will reach IMO Tier III compliance.

    Pre-engineered medium-speed generating sets

    Wärtsilä Auxpac generating sets are available in a selected range as pre-engineered and pre-commissioned auxiliary generating sets. The common baseframe is optimised for the package, which together with the compact design of the engine and the selected generator, offers unmatched power-to-space and power-to-weight ratios. Other benefits of pre-engineering include readily available documentation, which also includes models in Tribon® format, and short lead-times.
