For decades, we have specialized in machines for the graphic industry. Today, we are a market leader in vacuum technology for the medical and bakery industry.

Our experience and innovative spirit are valuable in developing all kinds of distinct machines.

All our developments have two things in common: increased efficiency and performance for our customers. Our solutions are precisely tailored to customer requirements. Investments in Durrer machines also pay off in the long-run – guaranteed.

Family business since 1949.

We are somewhat proud of our history. It all started very small, in a humble village between the Rigi mountain and Lake Lucerne.

Today, our machines are in use all over the world.

Electric workshop in Küssnacht.

Durrer Spezialmaschinenbau AG looks back on a long history. It was a long way from the small electrical workshop of brothers Franz and Klaus Durrer in Küssnacht to a globally active industrial company.

Franz and his wife, Trudy Durrer-Kistler, then laid the foundation stone for today's Spezialmaschinen AG. In 1958, they founded the workshop for electromechanics and development and moved into their own business premises.

The second generation.

The company grew slowly but steadily. In 1980, there were 13 employees; in 1985, 20. And in 1989, the sole proprietorship Franz Durrer became Durrer Spezialmaschinen AG. When the second generation, Bernadette Reichlin-Durrer and Ludwig Durrer, took over management of the company, it had 35 employees.

That was in 1995, and in 2000, the company took over additional premises in the newly opened "Zentrum Hohle Gasse" in Immensee. With 55 employees, the old location had become too small.

Corporate DNA.

Despite all awareness of tradition, the company has always looked to the future. The joy of innovation and the urge for further development lie in the company’s DNA. Permanent growth ultimately led to the company moving to Immensee in 2018. Here, we continue to provide our employees with exciting jobs.

We offer our apprentices an ideal start to their professional life, and to all employees an environment in which work is enjoyable. Together, we are shaping the future of Durrer Spezialmaschinen AG.

Company's history

Our milestones are what make us so proud. Here is the complete history of our traditional and innovative company.


Franz and Klaus Durrer establish the company "Gebrüder Durrer" in their parents' laundry room (repair of small devices).

And by the way: The People's Republic of China was founded on the same day.


When the voltage of the Swiss power grid was adapted from 500 to 380 volts in the 1950s, the company developed the winding machines necessary for the conversion. Picture: First prototype of an armature winding machine and start of its production.

60 employees work for customers all over the world and in various industries.

Durrer - Yes, that's who we are!

Unique special machines.

Every one of our special machines is unique.

We develop them just for you and your exact requirements. From conception to commissioning and beyond, plus special machines for highly individual tasks.

Whatever your requirements, we find the solution.

We love the challenge.

Do you have a particular idea in mind? A task for which no machine exists yet? Then challenge us. As soon as it becomes complex, our engineers and specialists are in top form. They then tinker until the perfect solution is found.

Their experience, extensive know-how, and the joy of technological sophistication help them to do so.

Everything from one source.

e analyse your situation and your needs. We develop, design, and deliver. We are also there for you afterwards: maintenance, support, and upgrades. This makes us efficient, our solutions well-thought-out, and your investment valuable in the long-term – these are demands that have shaped our family business since its foundation in 1949.

They guarantee reliable high quality, and they are passed on from generation to generation.

Family tradition in the 3rd generation.

Yes, we are a family-run organisation.

Sister and brother in the management: yes, we're a real family business. Decisions are made democratically throughout the Executive Board, with the Board of Directors and divisional management according to our values and mutual respect.

With Samuel Durrer, Ludwig Durrer's son, the next generation is already part of the company. As a mechanical engineer, he has the training and the skills to be a suitable successor.

Entrepreneurship at heart.

Bernadette Reichlin-Durrer and Ludwig Durrer absorbed the entrepreneurial spirit at the family table from an early age.

The company has always been a topic of discussion when sitting together. However, the siblings initially went their own ways. Gender played no part in this: they were both encouraged in their abilities and interests. And yet, it soon became clear that their professional future lays in their own family business.

Bernadette joined the company in 1982. Ludwig followed in 1993. Since 2021, Ludwig Durrer is the sole shareholder of Durrer Spezialmaschinen AG. He has taken over the company shares of his sister Bernadette Reichlin-Durrer and long-time co-shareholder Norbert Ott. Both have also left the Administrative Board. The changes were resolved by mutual agreement and in the sense of an optimal succession plan.

Company with team spirit.

The joint takeover of the business in 1995 was apparent. The division of tasks, too, due to her training path: Bernadette Reichlin-Durrer is responsible for commercial, organizational and financial matters, and Ludwig Durrer for the technical area.

It was also clear that someone from outside the family would complete the management, added by a Board of Directors with a wealth of experience and specialist know-how.

Today, decisions are made democratically - entirely in the interests of the company and far-sighted planning. And indeed, disagreement rarely occurs.

In one location.

A unique feature of our company is that we work together closely, and distances are short.

This makes us efficient, as we can combine know-how and experience. It also makes our tailor-made solutions and prompt service possible.


Swiss made machinery & service solutions. Since 1949.

Our teams

Mechanical and electrical development

The "tinkerers and developers".

New, special machines and optimised spare parts for existing machines are produced here: we always find a solution according to our customer’s ideas and requirements. We design, draw and test different variants and new technologies using our great experience in mechanical and electronic development, where the right software makes the machines work.


The "all-rounders".

In the production department, we turn, mill and drill - all machining processes are carried out in-house. The surface treatments that we can order from our long-term partners from the surrounding area are also part of this.


The "assemblers and wire connectors".

The individual manufactured parts are put together in the assembly department to form new machines or assemblies for existing machines. At Durrer Spezialmaschinen, we practically do everything ourselves: from manufacturing the smallest individual part to the moment when the machine is on the ramp ready to be signed off.

After-sales and customer service

The "troubleshooters".

Initial contacts are made via our customer service. But even after that, we always stay in touch with our customers, usually for years or decades, and are always there for them. Our customer advisors forward enquiries to the appropriate department or offer advice themselves - they also have a technical background. It is important that customer service always keeps an overview and ensures that the customer is helped in an uncomplicated manner. To achieve this, we organise service, the right spare parts, delivery, and everything in between quickly and efficiently.

Sales Department

The "Project Managers"

In sales, close cooperation with the development department is particularly important. This is because feasibility and cost framework, as well as possible implementation, must be analysed in detail at a very early stage of a new project. This is the only way we can advise customers professionally from the very beginning without raising false expectations.

Vacuum cooling

The "specialists".

We have been developing and manufacturing vacuum cooling systems for third-party suppliers for a number of years. Our vacuum cooler showcases our experience and concentrated know-how as a specialist for vacuum technology.


The "Internists".

The continuous collaboration between all departments makes our company special. Even in administration, the exchange is permanent and intensive. After all, satisfied customers and long-term business relationships are just as important to us.

By our side for support:
Our Administrative Board.

«Curiosity and openness to new technological developments are in our DNA. In this way, we ensure that, as a company with a long history, we also have a successful future ahead of us.»
