  • Newest 60 Hz generator set based on mtu Series 4000 G05 engine coupled with integrated aftertreatment system can achieve lower emissions than those required by EPA Tier 4
  • System specifically tailored for stricter emissions limits in non-attainment areas

The new mtu Series 4000 G05 generator set from Rolls-Royce provides a fully integrated power solution that features direct coupling of the engine and aftertreatment for a smart system from a single source that can optimize emissions performance. Based on the proven reliability of the mtu Series 4000 engine for power generation applications, this latest edition features a 12V configuration and comes in four ratings for 60 Hz standby applications: 1350 kWe, 1500 kWe, 1600 kWe and 1750 kWe.

“This latest version of the mtu Series 4000 offers additional emissions flexibility that our customers are looking for,” said Mark Halbert, Director of Engineering for Power Generation at MTU America Inc. “When coupled with its SCR aftertreatment system we can meet the strict emissions limits that are mandated in non-attainment areas,” he continued. “The engine can handle more back pressure, so the size of the aftertreatment system can be smaller, giving it a smaller overall footprint, which our customers appreciate.”

The aftertreatment system consists of a diesel oxidation catalyst, diesel particulate filter and selective catalytic reduction system. It was jointly developed with the Series 4000 G05 engine so that the two work seamlessly together, with all development taking place in-house within the Power Systems business of Rolls-Royce. The plug-and-play design of the generator set and aftertreatment system makes it attractive to customers as it simplifies the design and specification for the emergency power system within the overall project.

The mtu Series 4000 G05 generator set is certified to EPA Tier 2 without aftertreatment. It is available with optional certification to UL 2200 and CSA. All mtu diesel generator sets undergo rigorous Performance Assurance Certification that tests the generator set to ISO 8528-5 for transient response, verifies product design, quality, and performance integrity; and includes prototype and factory testing. The mtu Series 4000 G05 accepts rated load in one step per NFPA 110 and has a permissible average power output during 24 hours of operation of up to 85%.

The mtu Series 4000 G05 is available for order now, with start of delivery later this year. The engines are manufactured at Rolls-Royce’s mtu Aiken Plant in South Carolina and the generator sets are manufactured at its facility in Mankato, Minnesota.
