Condair climate precision for Actelion’s architectural icon
The Actelion Business Center in Allschwil, designed by Herzog & de Meuron, is a six-storey architectural landmark featuring complex deconstructivist design. Its intricate structure required extensive engineering and materials. Condair’s DL hybrid humidifiers ensure a consistently optimal indoor climate for its modern workspaces.
The Actelion business center
The striking Actelion Business Center in Allschwil is an architectural landmark designed by the renowned Swiss architects Herzog & de Meuron. Built in the expressive style of deconstructivism, the beam-like structure stretches across six stories, creating dynamic sightlines both through the building and out into the surrounding environment. Inside, employees benefit from generous recreation areas, inner courtyards, terraces, and a contemporary working atmosphere tailored for around 350 staff members.
Realizing the building’s complex geometry required an exceptional level of precision: a three-dimensional facade structure, 1,500 detailed construction drawings, 2,500 tons of steel, and 3.8 kilometers of lattice girders were needed to achieve the sophisticated load-bearing system. Complementing this technical masterpiece, Condair’s innovative DL hybrid humidifiers deliver impeccable humidity control, ensuring an optimal and comfortable indoor climate throughout the building.

Condair DL
The Condair DL is the next generation of the Condair Dual2—the world's most successful system for adiabatic humidification. Its hygienic credentials have proven successful in practice and were verified and certified by independent organizations with public responsibility.
Hybrid humidification relies exclusively on the advantages of atomization and evaporation. This results in the sustainable resolution of key problems which can emerge when these technologies are used in isolation. The humidification system is therefore the first choice in terms of hygiene, energy efficiency and cost-effectiveness.
