We are Zwart

Zwart has almost 90 years of experience in power generation. The company was established by Henk Zwart in 1930, in the port of IJmuiden where you will still find us today. Wherever you are in the world you are never far from a Zwart emergency power system; to date we have installed around 7,000 systems all over the world. Our head office in Ijmuiden includes over 6000 square meters of production space where our systems are designed, assembled, tested, inspected and maintained. It also includes our parts warehouse, our test bays and our training and simulator facility.

There are now around 7,000 (emergency) power installations worldwide

Our people

Today Zwart has over 100 highly trained, motivated professionals across the full range of technical disciplines. Many of our colleagues have been with us for decades but along the way we have also trained and developed many young talented people in all aspects of emergency power. Because emergency power is not something they teach you at school; you also need to learn on the job, and with experience comes knowledge. Our people are proud of the work we do, proud of the quality of the solutions we deliver. We work together as one team, and together we achieve great things.

Quality, trust and honesty

Long-term relationships

The better you understand each other the more added value you can provide. That is our philosophy. It allows you to be successful together. Long term relationships form the basis of our business and much of our success is built on relationships going back more than 3 decades. So when we start a new relationship we plan on staying around for a long time.

When it matters most

The Zwart standard

For almost a century we have been the emergency power expert of choice in Europe and beyond. And we want to keep it that way. How? By staying ahead in terms of our knowledge. By training and developing our people. By devising smart, innovative emergency power and off-grid solutions and realising them. No environment is too complex for us. We will always find a solution, and deliver it as promised. We do so thanks to our obsessive solution-oriented approach, our experience gained on those 7,000 projects and our creativity. We always set the bar high for ourselves. As high as we can. And it shows. That is the Zwart standard.

Connected with the environment

Responsible employer

As a responsible employer the health and safety of our employees is paramount. No job is so important that it can’t be done safely. Zwart is proud to be certified as a socially responsible business. We invest in our people through training and we, in turn, give them great responsibility to make decisions. Outside our business we strive to support a selection of community initiatives in the places where our people live and work.

Green initiatives

Innovative power for the environment

At Zwart we realise that as an organisation we, together with our suppliers and clients, bear responsibility for the future of our planet. We are therefore committed to developing innovative projects, products and solutions that minimise the burden on the environment. Examples include our HyCom1 hybrid solution that enables solar and conventional power sources to work together effectively, filters that significantly reduce generator emissions and, closer to home, solar panels on the roof of our facility in Ijmuiden that ensures we are self sufficient in electricity.
