Power Generation Enterprises stocks one of the largest pre-owned MTU generator inventories in the western United States — over 50 Detroit/MTU generator sets available from our Santa Clarita, California facility. Our inventory covers the MTU Series 2000 and Series 4000 platforms, from the compact 16V2000 in the 900–1,000kW range up to the 20V4000 producing 2,500kW and beyond. These German-engineered generators are the premium choice for data centers, hospitals, and industrial facilities where fuel efficiency and build quality are non-negotiable.
MTU generator sets consistently deliver 5–10% better fuel efficiency than comparable Caterpillar or Cummins units in the same power class. The Series 4000 platform — particularly the 16V4000 and 20V4000 — is the engine of choice for hyperscale data center deployments, where fuel cost over a 20-year asset life is a primary consideration. Every MTU unit in our inventory has been evaluated for engine condition, alternator integrity, and control system operation before listing.
MTU vs the field: The MTU brand encompasses engines originally manufactured under the Detroit Diesel, Detroit MTU, and MTU Friedrichshafen nameplates — all part of the Rolls-Royce Power Systems group. Parts and service are available through MTU's nationwide dealer network and through Power Generation Enterprises directly.

MTU (Motoren- und Turbinen-Union) traces its roots to the merger of Daimler-Benz and MAN engine divisions in 1969 in Friedrichshafen, Germany. The brand became a cornerstone of high-performance diesel technology for military, marine, and industrial applications. Detroit Diesel, the iconic American engine manufacturer, merged with MTU in 2000 under DaimlerChrysler, creating the Detroit/MTU platform that powers generator sets marketed under both names in North America. Today, MTU is part of Rolls-Royce Power Systems, ensuring continued development of the Series 2000 and Series 4000 engine families that define large-scale data center power generation globally.
MTU Series 4000 engines deliver 5-10% better fuel efficiency than equivalent Caterpillar or Cummins units — translating to $500,000+ in lifetime fuel savings per unit in data center applications.
MTU 16V4000 (2MW) and 20V4000 (2.5MW) are the most specified large generator engines in hyperscale data centers worldwide, chosen for power density and fuel efficiency.
Manufactured in Friedrichshafen, Germany to Rolls-Royce precision standards — tighter manufacturing tolerances, more rigorous factory testing, and longer design-to-overhaul intervals.
MTU Series 4000 engines are designed for the longest service intervals in the industry — reducing maintenance cost and downtime over a 20+ year asset life.
MTU's factory-integrated SCR system is the most refined in the generator industry, producing cleaner installations than the aftermarket retrofits common on competing platforms.
MTU covers 600kW (Series 2000) through 2,500kW+ (Series 4000), offering consistent engineering standards and shared maintenance infrastructure across power classes.

Commercial Generators: Complete Buyer Guide 2026Used MTU generator prices vary by platform and size. Series 2000 units (600-1,000kW) typically run $85,000-$185,000. Series 4000 units start at $175,000 for a 12V4000 (1,500kW) and exceed $450,000 for late-model 20V4000 packages (2,500kW+). MTU commands a premium reflecting its superior fuel efficiency and build quality. Call Power Generation Enterprises at (818) 484-8550 for current pricing.
The MTU 16V4000 produces approximately 2,000kW (2MW) in generator set configuration. It is the hyperscale data center industry's most widely specified large generator engine, chosen for class-leading fuel efficiency (5-10% better than equivalent CAT or Cummins units), high power density, and long service intervals.
The MTU Series 4000 offers 5-10% better fuel efficiency than the CAT 3516 at comparable power outputs. The CAT 3516 has a larger North American dealer network and broader parts availability. For data centers where fuel cost over a 20-year asset life is a primary factor, MTU typically wins the TCO analysis — fuel savings often exceed $500,000 per unit over that period.
Yes. MTU offers Tier 4 Final versions of the Series 2000 and Series 4000. The factory-integrated SCR system is more refined than many aftermarket retrofits. Contact Power Generation Enterprises for current Tier 4 MTU inventory availability.
The MTU Series 2000 covers 600-1,000kW (12V2000: 600-750kW, 16V2000: 900-1,000kW), suitable for commercial and mid-size industrial applications. The Series 4000 covers 1,500-2,500kW+ and is the standard for hyperscale data centers and large industrial installations — offering higher power density, better fuel efficiency, and longer overhaul intervals.
MTU Series 4000 engines are designed for 20,000-30,000+ hour overhaul intervals in continuous-duty applications. With factory-recommended maintenance, total service lives of 30+ years are achievable. Many first-generation Series 4000 units installed in the early 2000s are still operating in data centers today.
MTU generator parts are available through Rolls-Royce Power Systems authorized dealers across North America. Power Generation Enterprises can also assist with parts sourcing. Emergency parts availability is typically 24-48 hours for common scheduled-maintenance items.
MTU generators are best suited for applications where fuel efficiency and long service intervals justify the premium acquisition cost: hyperscale data centers (continuous partial-load operation), hospitals, large industrial facilities, and offshore/marine applications where fuel savings over a 20-year asset life are the primary financial driver.
