THE GAS-P0WERED SERIES 4000

OVER 20 YEARS OF TOP PERFOMANCE

The new natural gas genset offers the highest power density and the highest kilowatt-per-square-foot ratio in its class. Its smaller footprint enables a 30% improvement in power density compared to its predecessor. In multi-generator sites, fewer gensets are needed to achieve a given power output. The new natural gas genset also has lower installation costs. The natural gas power genset is based on the successful 4000 series, delivers from 776–2,535 kW, and has been optimized for hot and humid environments.

Benefits

Basic Benefits
Engine Benefits
Operational flexibility
  • A significant reduction in nitrous oxide emissions makes the natural gas genset a perfect fit for independent power producers (IPP) and combined heat and power (CHP) applications. With part-load performance down to 35% and a fast start option, its operational flexibility is also ideal for demand response applications. Low emissions - 250 mg/Nm³, 500mg/Nm³, (@5% O2)NOx – are achieved without external aftertreatment, even meeting the new expected German unburned THC emissions legislation (<1300mg@5%O2).
30 % MORE POWER
  • The natural gas genset has an effective engine power of 130 kWm / cylinder – the highest power density in its class thanks to its compact design and small footprint. It offers superb performance at high temperatures and high humidity for use anywhere in the world and delivers 30% more power than its predecessor.
LOW LIFECYCLE COSTS
  • All natural gas genset components are fine-tuned to ensure long service lives and deliver maximum uptime. Long service intervals and easy-to-maintain components mean low maintenance costs. Fast availability of spare parts and low engine oil consumption also help keep lifecycle costs lower overall, with cylinder head lifetimes potentially equivalent to TBO.
UP TO 44.3 % EL.EFFICIENCY
  • The natural gas genset achieves efficiencies of up to 44.3 %, delivering a significant improvement in fuel/energy utilization at high temperatures.
Ignition system
  • Ignition systems for individual cylinders allow for the most efficient level of operation for all cylinders, even with variable CH4content. The ignition system gives information on the state of the spark plugs.
Heat Recovery Unit
  • Well proven design perfectly suits the genset and provides the basis for optimized auxiliary efficiencies. The unit is fully integrated in the automation concept and is both safe and certified (CE).
Generator
  • Perfectly tuned to the engine and made by renowned manufacturers, the generator ensures a high level of reliability and optimum efficiency.
Digitally connected
  • The system is equipped with a data logger providing access to digital solutions from MTU, including remote monitoring, fast and reliable service support and – coming soon – further features such as predictive failure prevention and operational optimization.
Automation Systems MIP & MMC
  • Motor interface panel (MIP) with stand-alone MTU Module Control (MMC). The MMC provides all the functions necessary for controlling the system. All the auxiliary drives required for the CHP system can be operated from here. The integrated power circuitry minimizes the customer’s need for cabling on site.
Knock detection
  • Cylinder-specific knock detection and regulation protect the engine from abnormal operating conditions, and guarantee safe operation even with natural gas containing low levels of methane.
