Energy security built on nearly a century of expertise.

What began in 1930 as Dutch craftsmanship at sea is now the driving force behind the world’s most critical infrastructures. From our early expertise in marine engines to today’s advanced and complex energy systems, every Zwart project is built on precision, craftsmanship, and reliability. That’s how we deliver energy security when it matters most.

It all started with Henk. And we’ve been moving forward ever since.

On 10 September 1930, Henk Zwart laid the foundation for what Zwart is today.

Now, 95 years later, we’ve grown into a trusted partner in energy security. You’ll find us in hospitals and data centers, with growers, and across the industry.

Since those early days, much has changed: the technology, the scale, and the world around us. But our mindset remains the same: we approach every challenge intelligently, make sure it works 24/7, and don’t stop until it’s truly finished.

The transition to sustainable energy demands a lot from businesses. That’s why it’s vital to have a partner you can rely on, one that’s always there to deliver certainty.

Zwart is that partner. Always moving forward. For you. For the future.

Quality isn’t optional. It’s the Zwart standard.

At Zwart, energy security and delivering the best possible result come first. We never settle for half measures. We use the finest brands, rigorously test every installation in our own test facility, and leave nothing to chance.

Safety is built into everything we do, following the strictest standards for our people, your people, and your organisation.

The result: energy solutions you can trust 24/7. Because downtime is not an option.
