Reducing energy costs + Increasing safety
Innovative solutions for lift shaft smoke extraction from BK-Factory.
All In One systems (AIO) decrease building operating costs and ensure maximum safety at the same time. The idea behind this is both simple and ingenious: permanent openings in the lift shaft remain closed and open only in case of fire. This decreases heating costs. If the shaft openings are open continuously, as is the case in conventional configurations, heating energy escapes in an uncontrolled manner due to the chimney effect in the shaft. Closed shaft heads simultaneously increase comfort for people in the building, as there are no more unpleasant drafts in the interior. The AIO System of BK-Factory provides one of the world's most cutting-edge shaft smoke extraction solutions.

A true plus for lift shaft smoke extraction
The right solution for any lift shaft
Lift Beam systems are suitable for shaft heights from 8 to 200 m. An infrared emitter monitors the shaft for smoke.
It's easy to decrease energy losses.
AIO in use: Kontorhaus Alsterufer
This is why the new prestige project in Hamburg, Kontorhaus Alsterufer 1-3, has already received the LEED Gold award for ecological construction in the planning phase. D+H plays a role in this: the new building has five lift shafts, each outfitted with an All In One Lift Beam system. An outstanding feature: the Lift Status Transmitters (LSTs) are installed directly on the shaft and ensure ventilation is provided when and where it is needed. For example, if the CO2 value in the shaft increases, the air flaps in the shaft are opened automatically. If the acceleration sensors on the lift cars do not detect any motion for a certain period of time, for example after hours or on weekends, the flaps stay closed.
