Ask More.
Achieve More.

We’re a global team of EPC (engineering, procurement, construction) solution providers with modular fabrication capabilities who never stop asking “What more can we do?” to make a difference. As specialists in can making, renewables and traditional energy, we’re committed to asking more of ourselves with every project to create better solutions for our clients and the world.

Featured Project:

CANPACK (Olyphant, Pennsylvania)

“No one in the world is able to supply the same level of quality, service, and scope like Roeslein. I specifically admire the way the Roeslein team reacts to emerging problems. We can always talk and find an acceptable solution for both sides. Projects change, sometimes a few times per week, but everything is always taken care of under Roeslein’s supervision.”

Head of Investment Department, CANPACK

Renewables

Generating and converting renewable natural gas (RNG) might seem complicated, but with more than a decade of experience in engineering, manufacturing, constructing, operating and maintaining RNG systems, we won’t just make it look easy. We’ll make it work easy too.

Featured Product:

Biogas Upgrading Systems

“Applying [Roeslein’s] anaerobic digester technology, as well as additional circular technologies and environmental protections, to Smithfield’s hog farms is a significant and meaningful step towards addressing methane emissions at their source. Advancing and scaling proven GHG abating technologies like those used by Monarch is central to our mission at TPG Rise Climate.”

“The Roeslein team is always going the extra mile to ensure our projects are successful. Recently, their commissioning team came to our job site in the remote Wyoming desert and stayed for two solid weeks to ensure a critical project started safely, on schedule and without issue. A lesser effort likely would have still led to a successful outcome, but the added effort is why Roeslein has become a critical and trusted business partner for my team and Crowheart Energy.”

Modular systems

Our unique approach to designing and constructing modular systems allows every client to receive the custom solution they need. In many ways, completing a new modular system is like solving a puzzle. We’ll find the perfect place for every piece.

Featured Benefit:

“We were asked to convert a conventional build design to a modular design using offsite manufacturing.  The client was willing to invest in the engineering to improve safety, cost, and schedule.  Roeslein’s reputation for delivering quality engineering and preassembled modular solutions on short timelines was key to being chosen for the project.”
