safety+ comfort
Our system solutions provide fresh air in buildings - and can even save lives in an emergency
With high-precision window drives and intelligent control technologies, we ensure a healthy indoor climate and comfort worldwide, as well as plenty of air to breathe in case of fire.
From international airports to large shopping centres, architecturally sophisticated museums to complex office buildings and sports stadiums - D+H brings intelligent and certified solutions for state-of-the-art building automation to every facade and roof.
Architects, specialist planners, metal and facade constructors as well as system vendors know: Wherever D+H is labeled, there is also the plus of quality "Made in Germany" inside.
Regardless whether comfort, energy savings or safety is required: controlled air exchange is the fundamental operating principle of our solutions.
Natural smoke and heat extraction
In the case of a building fire, smoke and toxic combustion gases are the greatest risk to people. An efficient smoke and heat exhaust ventilation system (SHEV) reliably removes heat, smoke and toxic gases in case of fire. Escape and rescue routes remain smoke-free. The fire brigade and rescue services can reach the source of the fire in a targeted manner and evacuate people quickly. In addition, damage to buildings is considerably reduced and real values within the smoke-free layers are effectively protected from soot and ash. If smoke and heat developments are reported by the sensors in a building, intelligent smoke and heat extraction solutions from D+H immediately open windows and skylights in the upper wall or ceiling area. At the same time, other windows are closed to prevent smoke from entering the areas not affected by the fire, and supply air windows or flaps are opened, thereby using the natural chimney effect for smoke exhaust.
Mechanical smoke extraction
The thermal properties of smoke gases and fresh air are not always sufficient to ensure natural smoke and heat exhaust from a building. This can be remedied by the use of fans and smoke extraction channels. If the function of a smoke and heat exhaust ventilation system (SHEV) is achieved with motor-driven ventilators, it is referred to as mechanical smoke and heat extraction (MSE). These are usually planned and afterwards manufactured object-specifically, depending on the use. This kind of solutions usually consist out of smoke extraction ventilators, automatic air supply openings, smoke extraction or fire flaps, smoke detectors as well as a control panel.
Natural ventilation
With opening and controlling the windows in accurat positioning, the supply of fresh air and therefore the indoor air as well as the thermal comfort can be improved. By using natural power sources and thermics, controlled natural ventilation (CNV) offers an energy-saving, healthy, cost-effective and contemporary alternative to air conditioning systems and other mechanical ventilation. It requires comparatively lower investment costs due to lower installation effort and, at the same time, shorter construction times due to simple, quick commissioning. There are also lower maintenance costs due to low-maintenance technology and less energy consumption, as neither active cooling nor mechanical ventilation is necessary, which reduces the CO2 emissions. In practice, smoke extraction solutions are also often combined with natural ventilation.
Lift shaft smoke extraction
Lift shaft smoke extraction is realised at D+H with BlueKit solutions. They combine efficient and demand-optimised ventilation with safe smoke exhaust, while saving energy costs and ensuring safety and comfort in the lift shaft at the same time. The containment of power losses in the lift shaft is often ignored not only in the renovation of existing buildings, but also in new construction. Ensuring an airtight building envelope is now a central component in the planning of energy-efficient buildings. However, the permanent opening in the lift shaft for ventilation and shaft smoke extraction is often overlooked and causes high power losses due to a chimney effect. To prevent this from happening, BlueKit systems close the opening with a suitable ventilation element and regulate the ventilation or smoke extraction in the lift shaft by connecting various system components as required.
