• Services for your project

    In addition to the delivery of our ventilation components and the construction of complete systems, we offer numerous services for your planned construction project.

  • Ambient air flow tests

    Our in-house ambient air flow laboratory offers you specific analyses to ascertain the optimum thermal comfort conditions for your projects.

Individual consulting during your planning stage

Architects / interior designers

From establishing the basis of the project to the final design and execution drawings, up to and including pioneering solutions when it comes to energy management:
Kiefer offers you a comprehensive service from a single source, covering consulting, planning, engineering and production.



Practical experience gained in numerous, diverse projects helps us to come up with innovative solutions time and again. We can simplify the installation of components, reduce space requirements and improve performance.

End clients

We work together with you to develop individual air conditioning and ventilation solutions for new build and renovation projects. We also produce fire protection and smoke extraction concepts for air handling systems.

Digital product dimensioning in just three steps

Based on your individual project data, we offer you a simple way to carry out an online product design in no time at all without time-consuming software installation. The programme provides you with possible product solutions including the desired length or piece division and a dimensioning data sheet for download.


We support your construction projects

As air conditioning experts, we offer you a full range of services in air handling technology – from the planning stage all the way through to commissioning. We see ourselves as your partner at all times, actively supporting you with our wealth of experience. In close cooperation with you, we find the best way to create the perfect indoor environment. We can be on hand with technically sound advice as soon as initial discussions begin between the end client and architect/interior designer, depending on the requirements of the project in question. The entire air conditioning system can be designed by us, based on the future use of the property.

Research and development

Optimised processes and reliable systems
In the Kiefer Development Centre, which covers around 400 m², our air conditioning engineers work tirelessly on innovative and future-oriented solutions. They develop new, environmentally compatible components, carry out aerodynamic and acoustic tests, and optimise ventilation, lighting and control systems.

System verification for new projects
In our ambient air flow laboratory, we also conduct ambient air flow analyses on your behalf. In close consultation with you, we set up 1:1 model interiors, where we analyse thermal comfort levels under summer and winter conditions. The resulting test data is used to verify the targets set.

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



  • Air flow tests for customers
