Wärtsilä Auxpac

Pre-engineered medium-speed generating sets
The Wärtsilä Auxpac generating sets are supplied as pre-commissioned standard packages that ensure the availability of electrical power in sufficient quantity as and when it is needed. Wärtsilä Auxpac generating sets cover an electrical power output of 500 to 2,800 kWe for either 50 or 60 Hz operation.

Through modularization, the generating sets can be built to a high, comprehensive specification for a competitive price. Wärtsilä Auxpac generating sets provide easy installation, easy operation and low operating costs.

The medium-speed generating set range running on heavy fuel oil is based on Wärtsilä 20 and Wärtsilä 26 engines, which are well proven in shipboard auxiliary service. The generating sets are supplied for operation on the same heavy fuel oil as the ship’s main engines.

Easy to use documentation such as drawings, operating and maintenance manuals is provided either in digital or printed form covering all commercial and technical aspects.

Wärtsilä provides project management and experienced marine engineering to support the design and installation. Installation and commissioning procedures are standardized and well documented, which allows shipyard staff to build up their proficiency and ensure a trouble-free start to shipboard service.
