Benefits and Features

  • Anti-knock control and cylinder balancing protect the engine from overload and ensure reliable operation
  • State-of-the-art turbocharger A140 with Wastegate ensures full performance even under high temperatures and higher altitudes
  • Higher reliability and lower maintenance costs due to open combustion chamber technology

  • Miller valve timing and optimized compression ratios ensure high efficiency and low fuels costs
  • More profit for your plant
  • Long maintenance intervals and general overhaul only after 80,000 oh allow an operation of 10 years without general overhaul
  • Flexible fields of application also with fluctuating gas qualities due to Total Electronic Management (TEM)

  • Savings of up to 4,000 liters of lube oil per year compared to comparable gensets
  • Improved components reduce lube oil consumption
  • Lower operating costs due to 30% lower lube oil consumption in comparison to similar products
