Well-conceived drive solutions make even the most difficult window construction projects a success
D+H, the specialist for smoke extraction and natural ventilation, is making an appearance in Nuremberg and bringing along innovative installation solutions and proven drive technology for window fitters. This includes a new bracket with 4 axes for opening a trape-zoidal window. Another innovation is the smart BDT Advanced fitting drive for user-independent ventilation with bottom-hung windows. The booth will be showing new designs and application options for tried-and-tested chain drives, rack and pinion drives, and louvre drives, in addition to a side-hung vent bracket with a folding function for larger opening widths. In addition, the trade fair will provide an opportunity to use myCalc, the professional SHEV and NSHEV online calculation software. The presentation of D+H at FENSTERBAU FRONTALE is truly living up to this year's slogan: "Craftsmanship meets technology".
Whenever high-profile architectural projects are being implemented, it is not uncommon for stringent demands to be placed on the window fitter. Particularly when smoke and heat exhaust ventilation is involved, the aesthetic demands of the architects clash with the requirements from standards and the limitations of what is technically feasible. Product solutions and service offers from D+H put window fitters in a position where they can master these challenges.
Innovative bracket solution for heavy trapezoidal windows
In special cases, glass façades with sophisticated architecture can only be implemented by installing trapezoidal window surfaces. Architects usually no longer consider it an option to use rack and pinion drives to automate these windows because they are too visually obvious. It is much more aesthetically appealing to install the strongest D+H CDP chain drive using the newly developed bracket with 4 axes. This allows the drive itself to be mounted parallel to the window profile. The new bracket makes it possible to open even heavy trapezoidal windows with just one chain drive. Moreover, only a single fastening point is required for the bracket near the chain outlet. There is no need for other brackets to fasten the drive. Even the largest trapezoidal windows can be reliably automated if they are combined with the CDP 1500 chain drive—one of the strongest drives on the market.
Bracket with folding function – large opening angles for side-hung vent windows
Large-area side-hung vent windows require powerful drive solutions due to the pressure and suction forces acting on them when the wind is blowing. Ideally, only chain drives without a side bow chain are considered for this. A straight drive chain has a higher rigidity and therefore has no trouble opening, closing or holding side-hung vent windows, even under substantially higher wind loads. Combining the new, extremely quiet CDC drive with a side-hung vent bracket featuring a folding function enables exceptionally large opening angles of up to 60°—even without a side bow chain.
Christoph Kern, Chief Sales Officer of D+H Mechatronic AG, is confident that "The development of such bracket solutions underscores our role as a driver of innovation in the industry. The combination of power, aesthetics and functionality of the D+H products enables window fitters to satisfy even the most unusual requirements of contemporary architecture."
Smart window drive – the new BDT Advanced for bottom-hung windows
Window fitters now have additional application options for automat-ing the ventilation of buildings and rooms. D+H has taken its ele-gantly designed BDT fitting drive and made further refinements to it so that it can also be used on bottom-hung windows. The new BDT Advanced opens windows with activPilot ergo fittings from Wink-haus and even provides user-independent or time-controlled op-tions for doing so. The latest design of the D+H window drive can be controlled using either a wireless remote control or a smartphone. This innovative drive can be used in aluminium, PVC or wooden window designs.
Powerful louvre drive – the LDx with additional options
In designing façades, louvre windows are a favourite option among architects who need a functional element for creating window openings. In response to the trend of using windows with increas-ingly large areas, D+H has completely redesigned its LDx drive for louvre windows. The strongest version of the drive can open and close large, heavy louvres using a compressive and tensile force of up to 1800 N. For exceptionally heavy louvre windows, the AD-VANCED version even allows up to eight drives to be activated syn-chronously. Upon request, the housing can be painted in many RAL colours. By having its infeed line completely integrated into the window profile, the drive mounted directly on the profile remains nearly invisible. With respect to safety, the LDx satisfies the specifications of the Machinery Directive by using active anti-trap protection. Thanks to the IP44 protection class, the LDx is protected against water spray, making it suitable for outdoor use. The clever drive technology in the LDx provides more than safety and security—it also offers max-imum comfort, because its operating noise is barely audible. The latest design is making its debut at Fensterbau: the fail-safe function rounds out the LD product portfolio. In case of fire, this function ensures that the complete louvre can be either opened or closed one time, even if the entire building is affected by a power cut.
Aesthetics and functionality – invisible, synchronised CDC and VLD drive solutions
For more than 50 years, D+H products have been providing for a safe, healthy and comfortable atmosphere in buildings around the world. The proven technology Made in Germany continues to open up exciting new application options.
D+H drive solutions are the top choice for applications that require smoke extraction and natural ventilation while meeting the most stringent demands for aesthetics and functionality. It makes no difference here whether the window profile is made of aluminium, PVC or wood. The automation system for the windows remains completely hidden with the use of CDC Series chain drives and VLD Series lock drives which are fully integrated into the window profile and synchronised with each other. D+H solutions of this sort are found, for example, in the Henninger Tower in Frankfurt (architects: MEIXNER SCHLÜTER WENDT) and at 152 Elizabeth Street in New York City (architect: Tadao Andō).
Tried-and-tested classic – the low-maintenance ZA rack and pinion drive, even in extreme conditions
D+H rack and pinion drives in the ZA Series have already proven themselves time and time again in extreme conditions, such as in swimming pool facilities. In these cases, it is advisable to equip the rack and pinion drive with the WS option. This protects the drive against such harmful factors as the effects of air in swimming pool facilities (which usually contains chlorine) as well as spray water. This protection is achieved through particular specifications for the components and materials. Individual parts in the WS option are made of V4A stainless steel. This steel is particularly resistant to corrosion caused by spray from sea-water or chlorinated water.
Planning support for window fitters – face-to-face meetings with highly skilled experts
D+H has comprehensive expertise on the globally relevant standards and regulations for smoke extraction and ventilation. D+H provides various options for digital planning support for smoke and heat exhaust ventilation in applications such as fire protection strategy implementation in buildings.
The professional online software myCalc helps with calculating the required smoke extraction area of the windows. D+H provides BIM-capable data for all drives and other products to support the building planning. D+H is also a certified partner for window fitters—both for risk assessment of power-driven windows and for implementation of the corresponding protective measures. This is a particular advantage for window fitters who are acting as responsible installers and need to minimize liability risk.
In the words of Mark Nowotny, Head of International Sales of D+H Mechatronic AG, "Beyond window actuators and drives D+H pro-vides tailor made automation solutions for Venting and Smoke Ex-traction. Our specialized application engineering and international sales team is eager to fulfil your expectations and demands. In addi-tion D+H’s international certified partner network will provide you the service, assistance and consultation on site, which is needed to make your project a mutual success."
D+H is at FENSTERBAU FRONTALE 2020 in Nuremberg from 18 to 21 March – Hall 7, Stand 455.
