Rheinhallen in Cologne

Rheinhallen, Cologne

In 1922 the former mayor of Cologne, Konrad Adenauer, had already laid the foundations for the Rheinhallen with the initiation of the Cologne Trade Fair Company. The complex of buildings, protected as a historic monument, directly next to the banks of the Rhine in the Deutz district of Cologne was a trade fair venue from 1924 to 2005. Despite numerous refurbishments and modernizations, especially after World War II, the uniform brick building of 1928 can still be recognized, having dominated the panorama of the right bank of the Rhine for decades.

In 2005 the Rheinhallen was handed over to the City of Cologne. For the new main tenant, the media group RTL, including TV networks RTL, VOX, Super RTL and the news network n-tv, the interior of the original halls was completely stripped out. Two four-story buildings were inserted into the existing facades as part of the conversion. The Condair ESCO pressurized steam distribution system guarantees hygienic humidification of the highest standard.


Pressurized steam distribution system

Condair ESCO

Condair ESCO humidification systems for existing steam set the standards. The key element is the TÜV (German Technical Inspection Association) certified steam connection unit. The functional elements are fully integrated into it, in a design that guarantees fault-free steam connection.

Costly seals and pipework are superfluous. Installation is calculable, quick and cost-effective. The modular steam distribution system with its patented steam nozzles needs no jacket heating. This effectively prevents unnecessary energy consumption even during downtimes. All seal points are included in the factory delivery. This simplifies the entire equipment installation significantly without running the risk of leaking pipe connections.

Patented rotary disk valve

The valve operating mechanism is designed as a rotary drive, supplying high accuracy and reliable operation. The low actuating forces needed by the rotary slide valve and the direct power transmission allow for a compact and space-saving design. Conventional electrical and pneumatic humidity controllers can be connected.

The ceramic valves close with absolute tightness. When the system is switched off they prevent steam from entering the ventilation system and they do this without any additional shut-off device. Undesirable condensate buildup is thereby safely prevented without additional measures.

Condensate-free steam with
patented center-flow nozzles

The patented steam nozzles remove steam only from the main flow of the distribution pipes where the steam is hot and condensate-free. In this manner they ensure that the air hoses behind the distribution system remain dry. Made of solid stainless steel, they work reliably, are long-lasting and resistant to aging, and do not leak.

Homogeneous steam distribution
and shortest humidification distances

The patented steam nozzles remove steam only from the main flow of the distribution pipes where the steam is hot and condensate-free. Short humidification distances are decisive factors for reliable and hygienic steam humidification. In air conditioning systems there must be no vapor in air pipe installations. Damp surfaces, water accumulation and hygienic risks would be the consequence.

Condair ESCO DL40
The DL40 can be tailored flexibly to the air duct system using one, two or three horizontal steam distributors. This means considerable freedom in steam output and constructive design of the humidification chamber.

Condair ESCO DR73
The DR73 is always the best choice, whether you are going for the highest steam outputs or shortest humidification distances. The steam distribution system is individually designed around existing requirements and structurally tailored to the installation situation. The two-sided steam discharge on the nozzle assemblies allows homogeneous steam distribution over the entire cross-section of the air duct.
