Waukesha Gas Engines

Look at these beauties. When you’re rebuilding or doing maintenance, this is what you want to see on the bench. Not a questionable part from a mystery supplier, but the real thing. Here’s why genuine Waukesha parts matter: • Keeps your engine running the way it was designed • Cuts down on unplanned repairs and downtime • Gives you confidence you’re using the right part for the job When your engine’s pulling full load in the field, the last thing you want to second-guess is what’s inside.

Power isn’t always guaranteed, and when you’re running critical equipment, that’s a problem. Waukesha mechanical drive systems solve this by removing the need for external electricity altogether. Engines deliver torque directly to pumps, chillers, blowers and compressors - keeping systems online, no matter where you're operating. Here’s what that means in practice: • No transformers, power cables or reliance on grid access • Fewer components, making maintenance and repairs more straightforward • Efficient power transfer - with no energy lost to conversion • Operates on natural gas, propane, field gas and other available fuels • Offers both continuous- and intermittent-duty options, depending on the engine More than 1,800 Waukesha engines have been shipped for mechanical drive use over the past 25 years - supporting critical applications in water management, waste treatment, and oil & gas. Our Waukesha 275GL+, VHP, and VGF engines are built for reliable performance no matter the location or conditions.

Reliable engines need reliable support. At a natural gas site in Southern China, four Waukesha 275GL+ engines have delivered consistent performance for more than six years without a single failure shutdown - backed by a full maintenance program built around our Waukesha standards. Following Waukesha factory maintenance schedules, China Diesel Support Services (CDSS) Ltd. performs daily inspections and service to help protect uptime and extend engine life. Each unit has also been upgraded with our Waukesha ESM 2 controllers, enhancing operational efficiency, reliability and monitoring capabilities. With proven engine design and the right maintenance practices in place, the operator has achieved an average of 50,000 hours per unit - with no shutdowns. Strong engines, strong support and strong results - powered by Waukesha. China Diesel Support Services Ltd (CDSS) | RRPS MTU Distributor | Waukesha Innio Distributor

Before electric starters or digital controls, Waukesha engines were already hard at work in the oilfield. This photo shows one of our internal combustion engines powering a rig - part of a major shift away from steam that changed how drilling got done. That transition, led by early pioneers like James DeLong and Louis M. Pearce, marked the start of our long-standing role in oil and gas - one that continues today. Since those early days, over 30,000 Waukesha engines have been produced, still supporting critical operations in the field. Earlier this year, that legacy was featured in Cornerstones of Compression by Norm Shade, released at the Gas Machinery Conference. It’s a look at the people, technology, and milestones that helped shape this industry - and we’re proud to be part of it. We’re honored to help preserve that history and keep building on it.

Rebuild or replace? It’s a common question when an engine reaches the end of its run - and too often, remanufacturing is seen as the budget choice. But with our Waukesha reUp Remanufacturing Program, that’s not the case. This isn’t about getting more life out of your engine. It’s giving it a second life that’s better - with lower fuel costs, improved performance and significantly reduced emissions (up to 50% less CO₂). Waukesha engines can be upgraded to current specs using a detailed, multi-step remanufacturing process that includes: 1. Disassembly & Cleaning: Parts are stripped and cleaned to expose any hidden defects. 2. Inspection: Every component is tested against original specifications to help ensure quality. 3. Machining & Assembly: Expert technicians follow the latest specs to restore parts. 4. Testing: Every part is analyzed and certified before it leaves the factory. 5. Painting, Packaging & Shipping: Parts are preserved, packed and shipped in reusable packaging to further reduce environmental impact. It’s a smarter way to extend the value of your asset without starting from scratch or compromising on quality. Same engine, better outcome.

From South America to the Middle East, Waukesha engines are built for the extremes. INNIO Group’s Waukesha engines power critical operations around the world - from off-grid oilfields to high-demand energy hubs. Here’s how our technology performs across environments: • In South America, VHP7104GSI generator sets provide electricity to remote oilfields, far from any grid. • In Europe, rental generator sets deliver portable, reliable power for oilfield operations. • Across Asia, L5794GSI engines meet high energy demands in densely populated regions. • In the Middle East, our VHP Series Five engines are engineered to keep performing, even in relentless desert heat. Waukesha engines are trusted across continents for one reason: they deliver reliable power, no matter the challenge.

We recently hosted a Waukesha Technical Conference in Grande Prairie, Alberta, bringing together end-user customers for a focused, in-person event. This was built around real conversations with the people who run our engines every day. Attendees had the chance to sit down with Waukesha engineers, platform leaders, field service managers and applications specialists to share what’s working - and what needs to work better. We’re grateful to everyone who made time to join us and contribute their perspective. Your input helps shape the future of our product development. Another session is in the works for later this fall. If you're a Waukesha end user, keep an eye out. We might be headed your way.

Happy Canada Day to our Waukesha colleagues in Welland and across Canada. Last week, the team in Welland marked the occasion with a cupcake celebration - and a reminder of the pride and dedication they bring to their work every day. From manufacturing to engineering and support, your contributions are a big part of what drives Waukesha forward. Wishing you a safe and enjoyable holiday!

At the upcoming IADC DEC Tech Forum, David Azhocar will share how gas-fueled power systems are being used to support drilling operations - especially where natural gas is already available, and emissions reduction is a priority. He’ll walk through: • Examples of rigs using site gas to power operations • Measurable reductions in NOx, PM2.5, and CO2e • How these systems perform under real drilling loads The session will focus on what’s working, what kinds of results teams are seeing, and where this setup makes sense in the field. • July 1, 8:30 a.m. - noon, Houston • IADC DEC Tech Forum | “Rig Power Systems - Innovations Delivering Better Performance, Cost and Emissions”

Cleaner energy takes more than commitment. It takes engineering. Sustainability is built into our products and our mindset. • We’ve pushed for lower emissions and higher efficiency in every new release • We design with circularity, longevity, and lower impact in mind • And we look beyond engines - to how we operate, who we partner with, and what we give back. We’re proud to help move the energy industry forward, one step - and one engine - at a time.
