NATURAL GAS 

Economical. Reliable. Sustainable.

MTU Onsite Energy's natural gas generator sets are cutting-edge technology that offer combined heat and power (CHP), and combined heat, power and cooling (CHPC) solutions to generate power. Our products combine the highest performance with the lowest emissions in the 116 kWe - 2,535 kWe electrical power range.

Therefore, our natural gas powered CHP systems represent the  ideal solution for multiple applications:

  • Public buildings and residential utilities
  • Industrial & Manufacturing
  • Mission critical applications

Electrical power range: 116 - 420 kWe

Minimum space. Maximum efficiency.

Features of our Series 400:

  • Continuous development and optimization for more than 35 years
  • Meeting common industrial quality standards
  • Highest overall efficiency in its power range (up to 91.9%)
  • Sophisticated compact design 
  • Factory tested with comprehensive performance evaluation
  • Cylinder-selective knock control
  • 60 Hz / 130 - 360 kWe

    1. Gas engine
    Advanced and proven Series 400 gas engine, optimized for natural gas use. Combustion chambers ensure the highest level of efficiency in this performance category. For 60 Hz-Aplications the engine is rotating with a speed of 1800 rpm instead of 1500 rpm. Therefore a gear box is not necessary.
    2. Generator
    Optimally tailored to the engine and made by renowned manufacturers, the generator ensures a high level of reliability with the best degree of efficiency.
    3. Ignition system
    Ignition systems for individual cylinders allow for the most efficient level of operation for all cylinders, even with variable CH4 content. The ignition voltage display gives customers information about the state of the spark plugs.
    4. Mixture cooler
    The two-stage mixture cooler with large surface area improves engine performance and heat utilization.
    5. Knock detection
    Cylinder-specific knock detection and regulation protects the engine from abnormal operating conditions and guarantees safe operation even with natural gas with a low methane number.
    6. Crank-case ventilation
    High quality crank-case ventilation minimizes deposits in intake tract and combustion chamber and guarantees a continuously high level of performance.
    7. MTU Module Control (MMC)
    The MTU Module Control (MMC) contains all the important 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 need for cabling on site.
