Condition: good (used), Year of construction: 1994, operating hours: 7,430 h, functionality: fully functional, overall weight: 38,000 kg, fuel type: hybrid, power: 1,500 kW (2,039.43 HP), output frequency: 50 Hz, type of output current: three-phase, motor manufacturer: Wärtsilä, Diesel Generating Set – 1.5 MWe / 50 Hz Wartsila Vasa 4R32 LN-E This Wartsila diesel generating set has been used exclusively for testing purposes by VTT Technical Research Centre of Finland and has accumulated only 7,430 operating hours since new. Originally, it was built as a conventional diesel engine capable of burning various heavy fuels with viscosities of up to 730 cSt at 50°C. The engine was subsequently upgraded by Wartsila to comply with the LN-E model specification for their 32-series engines and it was equipped with adequate fuel feeding systems, cylinder heads, pistons and liners for dual fuel (DF) and gas diesel (GD) operation. The upgrade included the installation of anti-polishing rings, an increase in engine output, and the implementation of a completely new control system. The unit has been used to test various fuels and components on behalf of Wartsila. It has been exclusively serviced by Wartsila and remains in good technical condition. Over the years, Wartsila has installed new components and control systems. At present, the engine is equipped to operate in three different modes: As a conventional diesel engine using heavy fuel oil (HFO); As a Wartsila 32DF (Dual Fuel) engine using natural gas and light diesel oil; As a Wartsila GD (Gas Diesel) engine, where gas is compressed to high pressure and injected into the cylinder, ignited by a pilot dose of light diesel oil. Pedpfjyfflzjx Akfepr Naturally, to switch between modes, certain components—such as the turbocharger, cylinder liners, pistons, and cylinder heads—must be changed. All necessary components and much more additional spare parts (some brand new) are coming together in the same package. We can specify more in details upon request. Technical support for on-site installation can also be provided, subject to a separate agreement. The machine is currently located in Kotka and can be shipped by sea to any suitable destination port. Quotations are available upon request.
