About us

Your partner for any cryogenic solution

We have 60 years of experience with the most advanced projects, a more than passionate team and an unbridled drive to learn. Demaco has evolved into a genuine ‘Cryogenius’.

Specialist in cryogenics

Demaco is an expert in the field of cryogenic technology. We build infrastructures to facilitate the transport and application of industrial gases at extremely low temperatures. Between -160 and -271 ℃, to be precise. Since we work on both standard and highly advanced projects, we have built up a vast experience. Consequently, no cryogenic issue is too ambitious; we tackle every new challenge with equal enthusiasm.

Committed to the entire process

A real Cryogenius can do it all. Engineering at the highest level, devising and building the optimal designs, counteracting when needed, accurate testing, safe installation, error-free commissioning, providing the required documents and certification. Demaco is actively involved throughout the entire process. And if that is not enough, our customers can also visit our Webshop Vacuum for vacuum components, vacuum pumps, pressure gauges, and a whole lot more.

International focus

At a national and international level, Demaco is a well-known name in cryogenic techniques. We travel worldwide, work on large international projects, and have our representatives in France, Spain, China, and Malaysia. This allows us to serve all our customers to perfection. On location and in various languages.

The history of Demaco

Allow us to take you on a journey through the history of Demaco. Please take a look at the timeline below showing all of our developments, from our founding in 1960 to our future plans.


It all started back in 1960. Theo Dekker, an entrepreneur from Waarland, decided to start his own company. This company, later called Demaco, initially focused entirely on construction and agricultural machinery.

Soon after that, the need for machinery experts became evident within the sector, and Theo took advantage of this. Demaco was renamed -Dekker Machines and Construction- and adapted a new focus: machinery construction.


In the early eighties, the company unwaveringly pursued this specialization. In 1985, however, Demaco got in touch with cryogenic techniques for the first time, which immediately sparked an interest. Cryogenic technology is a highly specialized field; this proved to fit Demaco's ambition and eagerness to learn.


In 1989 the decision was made to focus on vacuum technology in addition to mechanical engineering and cryogenics. Meanwhile, cryogenic technology became one of the two pillars of the company, next to the specialism of mechanical engineering.


In 1996 Ronald Dekker, the son of Theo Dekker, took over the company. Ronald had lived in the USA, Algeria, and France for some time, and upon his return to the Netherlands, he took on the position of project manager cryogenics at Demaco.

Shortly after the handover, the decision was made to focus entirely on the new and specialist area of expertise for which there was much passion at Demaco. With this move, Demaco went from two business pillars to one specialization: cryogenics!


Demaco’s growth continued. And as the production accelerated, Demaco’s talented team grew as well. By 2000, the company had grown so much that to fit the entire team, several offices were needed. This resulted in the opening of a new and impressive head office in Noord-Scharwoude. The new headquarters offers enough space to accommodate the entire team under one roof.


Around 2009, Demaco, like most medium-sized companies, also noticed the effects of the economic recession and the global financial constraints that came with it.To deal with this in the best possible way, Ronald Dekker appointed Rob Groenendijk as interim manager. The collaboration went so well that Rob decided to buy in as a co-owner of Demaco. From that moment on, the company has two owners: Ronald Dekker and Rob Groenendijk.


Fortunately, the economy stabilized again, and Demaco's earlier growth again continued consistently. Demaco is now a well-known name in cryogenics and vacuum technology. Both nationally and internationally, a prominent brand with prestigious projects on its list of references and an outspoken opinion on creating the best cryogenic infrastructures.


What will the future bring for Demaco? No one can tell for sure. However, the course of action is straightforward.

Demaco continues to learn and specialize, with the appropriate frankness and flexibility to maintain its agility to respond to the latest trends and opportunities within a rapidly evolving industry.

By continuously growing and developing and entering into successful collaborations with both gas producers and research institutes, we will remain at the forefront of cryogenics while retaining our reliability and quality.
