01 — Services
What we take on
Areas of competence that complement each other in practice – from a single circuit diagram to the ongoing care of complete plant documentation.
02 — Industries
Where we are at home
Plants differ less in their technology than in what applies around them: standards, shutdown windows, unit numbers, evidence requirements. Fifteen industries where electrical design is needed – and where we know the constraints.

05 — Working together
The same people. From first conversation to completion.
FISEKON is an owner-managed family business in its second generation. You are not talking to an account team, but to the people who actually work on your project. Short decision paths are part of our working day, not of a mission statement.

Frequently asked
What prospects ask us first
What exactly does FISEKON GmbH do?
FISEKON produces electrical engineering designs for industrial plants and, as an external service provider, takes on technical documentation, revisions and project support. Added to that are article data and macro maintenance, digitisation of legacy drawings, standardisation, schematic generation, 3D control cabinet design, EPLAN workshops and maintenance agreements. The company has been active since 1998 and traded as DDT GmbH until 2026.
Which CAE systems do you work with?
Primarily EPLAN Electric P8 and ELCAD, plus WSCAD. For cable routing and control cabinet layout we add EPLAN Harness proD and EPLAN Pro Panel. We work inside the structure the customer already uses and continue existing systematics rather than replacing them.
Do you work on site or remotely?
Both, depending on the project. Where the actual state of a plant has to be recorded, we work directly on site, and we build project teams at the customer where that makes sense. Planning and documentation then also happen remotely.
Do you also maintain existing documentation on an ongoing basis?
Yes. That is one of our focal points: revisions, change management and the upkeep of documentation grown over years. Under a maintenance agreement we keep the documents permanently up to date without each change having to be commissioned separately.
Which industries do you have experience in?
Electrical design is needed across many industries. We structure our field into fifteen areas – from machinery and special-purpose machinery through plant engineering, automation, intralogistics, automotive, energy, chemicals, food, pharma, water and environmental technology, metals and heavy industry, buildings and infrastructure, rail and maritime technology to electronics, battery and packaging manufacturing. For six of them we have approved, anonymised project descriptions.
How quickly will I get a reply?
Usually within one working day. To begin with, the plant, scope and timeframe are enough; you then receive a realistic assessment. By phone we are available Monday to Friday from 8:00 to 17:00.
Where is FISEKON based?
The head office has been in Marienfeld (Harsewinkel), Stellmacherstr. 7, since 2004. A second office has existed in Gütersloh, Wagenfeldstr. 2, since 2007. We work throughout Germany and on European projects.
Contact
Tell us what it is about.
A phone call or three lines is enough. From the very start you talk to the people who will later work on your project – not to a distribution list.
