View open positionsOur values show in the work
We work carefully, dependably and with high standards for every detail. For us, quality does not arise only at the end but in every step.
At Erich Keller, craftsmanship, design, engineering, work preparation, project management, installation and organisation come together to form a shared result.
We take responsibility for our work, for deadlines, for quality and for what we promise.
We draw on experience but do not stand still. We improve products, processes and collaboration where it makes sense.
We deal consciously with material, energy, resources and time. For us, sustainability shows in durable products, efficient processes and responsible action.
We are an SME with short lines of communication, direct exchange and an informal first-name culture. People know one another and help each other out.

What these figures mean
Sulgen as the centre
This is where planning, production, workshop, project management and organisation come together. That creates short lines, direct coordination and clear responsibility.
Projects in Switzerland and abroad
Our solutions are used where spaces, workstations and technical systems have to function reliably.
Everything from a single source
From planning through manufacturing to installation, the disciplines work closely together.
A look behind the scenes
Furniture, interior fit-outs, system workstations and technical products are created in the workshop. Modern machines support the work. What remains decisive is craft skill: an eye for material, detail and quality – from the first cut to the final check.
On site during installation it becomes clear whether planning, manufacturing and coordination have worked cleanly. Our installation teams bring projects to the customer, solve tasks on site and ensure that high-quality solutions are installed as they were planned: calmly, precisely and reliably.
Work preparation and project management prepare what later has to work in the workshop and on site. Customer requirements, architectural plans and technical details become a deliverable project. Plans are reviewed, materials defined, processes coordinated and interfaces cleanly prepared.
Our engineering professions combine climate, air management, energy, control, construction, ergonomics and architecture. This creates technical solutions that integrate into spaces, use energy sensibly and work reliably in operation.
Behind every project are people who advise, calculate, purchase, coordinate, communicate and organise. They make sure that a first contact becomes a structured project – and that information, processes and customer support work reliably.
