Decentralised, compact, and ductless air handling units and rooftops – ventilation for every building

Do you need air renewal for your industrial building or distribution centre? We will be happy to advise you on the selection of our air handling units and rooftops

We take a holistic view of the building and support you in designing the most economical ventilation system. Ductless solution, compact design, and simple installation, saving time and cost during the installation process are significant benefits. The use of several decentralised compact systems on the roof supplies fresh air and ensures thermal comfort without complicated installation of ventilation ducts. Those air handling units offer many application possibilities: offices, public and industrial facilities, shopping malls, etc. All AHU variants have the same robust and extremely durable housing construction.

Clever details such as the integrated roof base reduce planning and installation effort and thus eliminates complications. We only use high-quality and efficient brand components (Siemens, Klingenburg, Ziehl-Abegg – “Made in Germany”) in the air handling unit. The integrated control system ensures that it is operated as required. The result is reliable operation and low operating costs.

Decentralised ductless air handling units

Ventilation Technology

Benefits of Decentralised Ventilation Technology:

In a decentralised set-up of ductless air handling systems, several compact units are arranged on the roof of the building. Simple installation (power supply and a simple roof penetration) saves time and investment costs. aeroSchwank C4 and C8 with their wide mounting options make many applications possible: shopping malls, distribution centres, public and industrial facilities, or any large spaces.

They supply fresh air and thermal comfort without the need of complicated ventilation ducts. This has a lot of benefits:

  • A reduction in pressure losses saves energy costs.
  • No cleaning of ducts.
  • Fewer collisions with other components in the building.
  • Lower planning efforts save investment costs.
  • Reduced maintenance.
  • Zone controls are easy to implement.
  • High redundancy: in the event of failure of the system, the other systems continue to operate.
