• Services

    In addition to the supply of ventilation components and the planning and execution of complete systems, we offer numerous services around your planned construction project.

  • Strömungsuntersuchungen im Labor

    Das hausinterne Raumströmungslabor bietet Ihnen gezielte Analysen der Komfortbedingungen für Ihre Projekte.

Individual consulting for your construction projects


Kiefer offers you the complete service from a single source: consulting, planning, construction and production.



Ongoing practical experience from various projects leads us to innovative solutions that simplify the installation of components, reduce the space requirements and improve the performance.

Building owners

Together we work on the development of individual air-conditioning and ventilation solutions. We realize ventilation concepts, as well as fire protection and smoke extraction solutions for new buildings and renovation constructions.


We support your construction projects

As climate experts, we offer you the entire range of services in ventilation and air-conditioning technology, from planning to commissioning. As your partner we actively support you with our experience. In close collaboration, we work out optimal solutions for the realisation of a feel-good climate. Depending on the requirements of the construction project our technically sound advice could already start with the discussion between the building owner and the architect. We take over the complete air conditioning design based on the future use of the property.

Research and development

Optimised processes and reliable systems
In the Kiefer Development Centre, covering around 400 m², innovative air-conditioning engineers are working on the future. This is where they develop new components that do not harm the environment, carry out aerodynamic and acoustic measurements, and optimise systems for ventilation, lighting and control.

System verification for new projects
In our ambient air flow laboratory, we also carry out flow analyses on your behalf. In close cooperation with you, we set up 1:1 model rooms in which we analyse the comfort under summer and winter conditions. The resulting measurement data is used to verfiy the targets set.

Analysis of comfort conditions in existing spaces
We can also carry out ambient air flow analyses in your buildings. This involves taking comfort measurements according to the relevant standards (DIN 1946/2, DIN EN 13779 and DIN EN ISO 7730). To complete our service to you, we provide a detailed report of all the important data and results.
