Bundesrat, Berlin

The history of the Bundesrat building in Berlin’s Leipziger Straße spans over a hundred years. The three-wing ensemble, planned by architect Friedrich Schulze-Kolbitz for use by the Preußisches Herrenhaus (the upper chamber of the Prussian parliament), was inaugurated in 1904. After the building was partially destroyed in the Second World War, it was renovated in the post-war period and then used for different purposes by various institutions of the East German government.

Following German reunification, the building was converted, equipped with Condair’s DL hybrid humidifiers, and has served as the seat of the German Bundesrat (parliament) since September 2000.

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.

Patented HygienePlus® method

Basically, air conditioners and humidification devices are not sterile areas. Even when humidifying water of drinking-water quality is used, this is never completely germ-free. Therefore, microbes can always settle and form hazardous biofilms in humidifiers and in damp areas of air conditioners. Suitable hygiene measures are therefore essential to hinder the growth and propagation of pathogens in adiabatic humidifiers. The germ diagram points out the rapid propagation of microorganisms when no appropriate steps are taken to contain them. The patented HygienePlus® method provides for healthy air and a lasting hygienic environment.

Energy-efficient low-pressure system

The low-pressure mode of operation translates to significant energy savings due to the lesser compression work. By combining the Condair DL humidifier and the reverse osmosis of the Condair AT2, even a pressure booster pump on the humidification system becomes superfluous!

Schematic layout

Low-pressure systems generally get by with a significantly shallower design depth than high-pressure humidifiers. Due to the arrangement of the evaporator ceramics so that they cover the full area, and as a result of the spray cone of the molecular diffuser nozzles, the entire overall depth of the Condair DL can be reduced to up to 600 mm. Thanks to its compact design, the humidification chamber can also be shortened, achieving a significant saving in materials.
