Efficient humidity control at Frankfurt’s Deutsche Bank twin towers
As one of Frankfurt’s most recognisable skyline landmarks and a symbol of German economic strength, the Deutsche Bank Twin Towers combine bold 1980s architecture with cutting-edge sustainability after their comprehensive green renovation. Condair is proud to support this iconic complex with advanced Condair DL hybrid humidification solutions that ensure hygienic indoor humidity, occupant well-being and energy-efficient climate control.
The Deutsche Bank Twin Towers
Frankfurt’s iconic Deutsche Bank Twin Towers (“Soll und Haben”), two 155 m mirrored high-rises completed in 1984, serve as headquarters for Germany’s largest bank and offer 120,000 m² of office space.
During the pioneering €200 m green refurbishment (2007–2010), the towers received new high-performance glazing and cutting-edge technology, cutting energy use by 50% and CO₂ emissions by almost 90% (LEED Platinum & DGNB Gold).
To ensure a healthy, comfortable indoor climate year round in this fully air-conditioned high-rise, precise humidity control is provided by Condair DL hybrid humidifiers.

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 organisations with public responsibility.
Hybrid humidification relies exclusively on the advantages of atomisation 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.
