Saving lives + Protecting property
Safety through smoke and heat exhaust ventilation
A person can go days without eating or drinking, but only seconds without sufficient air. Therefore, the greatest risk 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) system reliably removes heat, smoke and toxic gases. This keeps escape and emergency routes clear of smoke. Firefighters and emergency workers can reach the source of the fire efficiently and evacuate people quickly. This saves lives in emergencies. Additionally, building damage is reduced significantly and property within the low-smoke layer remains largely unaffected by smoke and soot.
-
Smoke levels in escape routes are kept low: People can exit the building more quickly in an emergency
-
Hot smoke gases are allowed to escape, reducing building damage
-
Smoke extraction is triggered in seconds, before firefighters arrive
-
Quick and easy maintenance
How smoke and heat exhaust ventilation works
If a build-up of smoke and heat is detected by the sensors in a building, or a smoke vent button is manually triggered, 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 reaching the areas not affected by the fire. Supply air windows in the façade admit fresh air.
As one of the first companies to use the motorised smoke vent and the first manufacturer of a certified smoke vent, we have extensive experience on the market. From stairwell smoke extraction to complex SHEV requirements for large buildings: D+H always provides a cost-effective, customised and safe system solution. Modular and digital.
With and without smoke extraction: a comparison
Intake air and exhaust air openings can be used to remove smoke and heat. Smoke is diverted to a stable smoke stratum above the area occupied by people.
Toxic fire smoke and extreme heat accumulate in the building. This endangers lives, hampers rescue efforts and causes the destruction of property.
Reliable product components for individual requirements
Our solution for complex smoke extraction situations
The digital smoke extraction controller with drives that communicate with the controller.
Maximum safety depends on precise communication. Our digital SHEV control panel is the first to provide bidirectional communication. 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 safety 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 extraction concept for any requirement.

The control panel for small smoke extraction projects
Smart design and easy to install: the CPS-B smoke vent control panel from D+H offers more than just smoke extraction
For many building projects, the tendering process for the electrical work also includes the installation of a smoke and heat exhaust system, for example in the stairwell. To control these mostly smaller systems, we recommend using the latest SHEV control panel by D+H, the CPS-B. The CPS-B significantly reduces the amount of installation work required, especially in wiring the system. This is ensured by the multifunctional, ingeniously designed housing of this compact control panel.
The housing is also designed to make the unit easy to service. The D+H development team drew on the combined practical knowledge of its own installers and customers from the very beginning.

Individual solution for maximum requirements
Application for Puławy Sports Centre
The Puławy sports centre required an exceptional smoke extraction solution for its large roof. Given the large playing area and general nature of the spaces, it was necessary to use flaps that are not only part of the smoke extraction system, but also components of the natural ventilation system. 40 oversized double-leaf top-hung windows were therefore used, each measuring 2 x 3 metres, equipped with DXD Series rack and pinion drives, and two single-leaf top-hung windows, each measuring 1.4 x 1.7 metres, also operated with DXD 300/800-BSY+HS Series drives.
In the event of a fire, the flaps installed in the Puławy sports centre open automatically, allowing toxic fumes produced by the fire to escape. All elements meet the highest quality standards: the flaps have been certified by the Polish certification department of the Deutsches Institut für Bautechnik (DIBt) for the reliability of their functional characteristics and the DXD rack and pinion drives have been issued with a certificate of approval from the Polish Scientific and Research Centre for Fire Protection (CNBOP).
