Leading technologies. Efficient solutions.
Inspired by our guiding principles, "Leading technologies. Efficient solutions." we have redesigned our roof-mounted central unit.
By combining photovoltaic facade modules, PVT modules, and heat pumps with natural refrigerants, we have developed an HVAC unit with a cross-disciplinary team that is capable of temporarily supplying itself with the necessary drive energy. This enables us to supply our production hall with conditioned air in an almost CO2-neutral manner.
Building information modeling.
Thanks to our large number of customers from the automotive and supplier industry, the pharmaceutical and chemical industry, and other sectors and areas for which we manufacture building services and process engineering systems, we are able to respond flexibly to requirements.
When it comes to project management, we rely on standardized processes in collaboration with our project partners. BIM enables us to engage in open and sustainable communication with planners, external contractors, and building owners. Furthermore, the BIM methodology allows us to further develop our internal processes and continuously expand them in innovative ways.
