SHEV smoke vent
Saving lives + Protecting property
D+H is the leading company for system solutions in the smoke and heat exhaust ventilation area.
A person can go days without eating or drinking, but only seconds without sufficient air. Therefore, the greatest danger for people when a building is on fire is the smoke and poisonous flue gas. In case of fire, an efficient smoke and heat exhaust ventilation (SHEV) reliably dissipates heat, smoke and toxic gasses. This keeps escape and emergency routes smoke-free. Fire brigades and emergency workers can reach the source of the fire efficiently and evacuate people quickly. This saves lives in case of emergency. Additionally, building damage is reduced significantly and property within this low-smoke layer is largely protected from smoke and soot.
If smoke and heat development is reported by the sensors in a building, intelligent smoke extraction solutions from D+H open windows and skylights immediately in the upper wall or ceiling area. At the same time, other windows are closed to prevent smoke from penetrating into the areas not affected by the fire.
As one of the first companies that used the motorised smoke vent and the first manufacturer of a certified smoke vent, we have comprehensive experience on the market. From extracting smoke from a stairwell to complex SHEV requirements for large buildings: D+H always provides a cost-effective, customised and safe system solution. Modular and digital.
Now, anyone can take part in the subject of safety
The first digital smoke extraction controller with drives that communicate with the controller.
Maximum safety requires precise communication. Therefore, our digital smoke extraction controller provides bidirectional communication for the first time. This means that the control panel not only sends its commands to the groups, but can also respond to the drives. The result is an intelligent system in which all components communicate with each other and exchange information. This allows the new control panel to ensure maximum security with precise communication.
An external interface can be used to control any component of the system from anywhere in the world. This is really quite smart and, thanks to the free cascadability of the system, it can also be used in any building. Due to the modular structure, CPS-M is the optimal system solution for implementing a sustainable and cost-effective smoke vent design for any requirement.
A true plus for smoke extraction
- Intelligent Advanced Communication Bus (ACB) function between controller and drives
- Networking multiple SHEV control panels using AdComNet (ACN)
- Software-assisted configuration of ventilation and fire compartments
- Optimal monitoring of the connected drives and simple error diagnostics
- Diagnostics, configuration and controller directly from the control panel
- Integration into existing building automation infrastructure via Modbus
- A stabilised network part with low ripple also makes it possible to connect to third-party drives
- The "Plug and Play" module technology allows modules to be added or removed easily
- Full-colour 3.5" TFT display enables convenient, intuitive and time-saving operation
- The compact design reduces the housing size, saves time, space and, therefore, money
Individual solutions for maximum requirements.
Innovative smoke extraction at RheinEnergie AG management headquarters
RheinEnergie AG management headquarters sets benchmarks for fire protection. The centrepiece of the building concept is a large atrium that is used as a multi-functional event location for thousands of people. In case of emergency, smoke has to be extracted from the huge space extremely quickly and reliably. This means maximum requirements for smoke extraction. The challenge for D+H was that there was not yet a standard assembly solution for the profiles of the installed supply air windows. This is why special consoles were developed for the top-hung window drives. Powerful CDP Series twin chain drives carry out the taxing work of opening large-format supply air windows.

Karl Maier, Technical Director
„Without the support of D+H, this large-scale project would not have been realised. From the very beginning they made the impossible possible and quickly had a solution at hand for every problem. This includes the new profile system, for which no suitable mounting solution was in existence. This makes the SHEV solution at RheinEnergie AG truly one of a kind.“
Two fire scenarios—one solution
How complex smoke tests save lives.
The atrium of the new management headquarters of RheinEnergie AG is intended to be used for as many different functions as possible. As a meeting point for the numerous employees or as an exhibition area for electric vehicles and other attractions. Therefore, the structure is subject to stringent fire safety requirements. Various smoke tests were conducted to verify that escape routes are kept smoke-free and usable in case of fire. For this purpose, numeric methods from fire engineering were used to simulate two fire scenarios: the first scenario is a car fire in the hall space and then a fire in the nearby cafeteria.
The results show that after a fire has burned for ten minutes, the smoke spreads over the entire area of the hall, but a lifesaving layer of air is formed.
