JUMAG and steam
Our Story

The best of everything combined in one device. For us, this is not just an empty phrase, but real history. JUMAG exists because a resourceful engineer refused to settle for second best back in 1961.

In those days, Theo Jungel's wife ran several successful cleaning companies. But her various steam boilers did not always run as they should.
Luckily Jungel was a technician and was able to repair a lot. This also awakened his inventive spirit: He discovered that each device had certain advantages. Why couldn't you just combine the best of each steam device?
No sooner said than done. the first "JUMA" (Jungel, Mannheim) steam boiler was created. And success proved him right: Finally a device that ran reliably and did its job brilliantly! It didn't take up unnecessary space and used less energy and water than other devices.
And with that, Jungel not only had a happy wife, but also laid the foundation for a successful company.
The philosophy is as valid today as it was then: The best of everything in one device!

Who we are

Some call it ambitious. Because always wanting the best requires perseverance and a healthy ambition.

But if you're now thinking we have a dog-eat-dog mentality: Far from it! We achieve our goals as a team. We are always open to ideas and changes and take responsibility towards employees, customers, partners and our environment.

We are like steam. We find ways to rise up and never stand still. JUMAG – the best of steam.

Sustainability at JUMAG

Sustainability starts with excellent quality and closes the circle through the recyclability of individual parts or entire devices.

We are constantly working to become even more climate-friendly in everything we do.

JUMAG steam boilers never run out of steam! We set the same quality requirements for our partners. The result: durable equipment, supplier products and spare parts, minimal maintenance.

Correct dimensioning makes a big difference. In addition, we are constantly working on finding new ways to save energy, for example by collecting water and feeding it into the steam cycle a second time or using hot flue gases from upstream processes.

In everything we do, we think outside the box – and include not only our products and services, but also processes and packaging in the most sustainable design possible.

Our equipment is so solid that it can be used profitably even after it have been used previously: So we buy back used boilers and recondition them. That's good for the climate and the budget!

Our next objective: The JUMAG company should also be CO2-neutral! Contributing factors are: regular modernisation, a fleet of hybrid or electric-powered vehicles and, for example, the offer for our employees to ride a company bike!

Proof of our capacity for innovation: Patents

Numerous patents show that JUMAG is one of the most innovative companies in the industry. Our products are being developed continually and represent the state of the art in steam generation.
