Over 150 years’ worth of experience spurs us on to innovate smart equipment solutions for tomorrow’s industrial plants. We ensure their regular heartbeat – even when we are challenged to repair the unrepairable. We understand the technical complexities because we have decades of expertise and an intimate knowledge of process technologies and materials.

Our high-quality equipment sets the pace for the fertilizer, chemical and petrochemical industries. When it comes to highly corrosive and critical media, we are known to be passionate about giving our equipment the right treatment. We focus on the specifics to make sure our clients get the most out of their processes – be it in the production of reactors, heat exchangers, concentrated nitric acid storage equipment, high-quality pressure vessels, special valves and piping or critical melamine equipment.

Production plant companies in China, Russia, India, the Middle East or USA, value our quality workmanship and superior services just as much as our troubleshooter skills. This, and a track record of about 3,500 international projects, has earned us international recognition and several awards as an Austrian Leading Company.

Our four specialized operations ACE, ACE Metalna, APB and SBN act in sync, from detail engineering, precision machining the big stuff, through to complex on-site assemblies and challenging in-situ repairs. Our teams warrant reliable, safe and eco-friendly solutions. Solutions which meet and exceed the highest international quality standards at the heart of every plant. Solutions our clients can trust.
