More power + Less costs

How voltage reduces wiring effort and cuts costs.

With an integrated 230 V smoke vent from D+H, even the most advanced architecture projects can be implemented cost-effectively. Without any compromises in safety, security or functionality. With D+H, you have the world's first 230 V complete system with EN 12101-10 approval at your disposal. Your advantage: even with high drive power, lower cable lengths and cable cross-sections can be used, saving money and effort. This enables the cable ducts to have a more streamlined design due to the narrower cable cross-sections, making designs with exceptional aesthetic appeal possible. The system is outstandingly well suited for complex buildings with heavy windows and correspondingly powerful drives. Typical examples include glass atria, industrial buildings, train stations, airports and other multi-purpose buildings with large open spaces.

Economical without fail

Highest performance at low cost: Our 230 V smoke extraction solutions.

The 230 V SHEV system is the only system in the world with a consistent 230 V power supply from the controller to the drives. The system is designed for use in complex buildings with long wiring routes and various heavy-load applications in the roof area. It offers the perfect combination of maximum performance and minimum wiring effort and expense. The control panels offer space for various plug-in units for smoke extraction and ventilation functions and are thus particularly simple to install and retrofit.

One thing is certain: safe operation with the 230 V EPS 401 emergency power supply. In addition to VdS approval, it also boasts a certified constancy of performance in accordance with EN 12101-10. The 230 V emergency power supply also has inverters with high-quality sine-output voltage, various status displays and a battery-powered impedance monitor. Defective batteries can be changed easily. This makes the 230 V emergency power supply both reliable and cost-efficient.

Integrated 230 V smoke vent in practice: HafenCity University Hamburg

The cutting-edge glass design of the new university for the built environment and metropolitan development at the Hamburg HafenCity would not have been possible without the 230 V smoke extraction solution from D+H. For this purpose, a SHEV system was developed with a 230 V emergency power supply system.

Five important questions about 230 V shev solutions

What advantages does a 230 V system have over a 24 V system?

The central point here is the cabling: For a 24 V system, I need larger cable cross-sections the longer the building's dimensions become. This doesn't make a difference if the length is 2 m, but when we start talking about more than 20 or 30 m, the cable cross-sections increase dramatically. A cable that is 100 m long, for example, can have a cross-section of over 16 mm². In larger buildings, we start having problems with structural aspects due to the heavy weight of the cables. The enormous advantage of a 230 V system here is that the system makes it possible to reduce the cross-section drastically. The normal installation cable can be used – in almost any length.
What practical implications does the 230 V system have?
The cost savings are enormous: In a 230 V solution, we can provide power to distant flaps and drives with significantly less expensive cables and lower weights. This makes the entire system more cost-effective. For smaller structures, such as a stairwell, a 24 V system is ideal. However, once we start talking about multiple storeys or an industry hall, for example, where there are larger cable routes, the 230 V solution is clearly more cost-effective.
What kind of cost savings are we talking about here?
Of course, we can provide some sample calculations. If we assume a cable route of 100 m in a complete SHEV system of a building, the total savings for control panels and cables would be several thousand euros. The differential becomes greater the longer the cable routes are. But the cost factor is not the only consideration. The visual advantages can also be a deciding factor. Large cable trays for a 24 V emergency power supply are sometimes difficult to reconcile with architects' ideas. In the 230 V solution, cable trays become much smaller and less obtrusive. Planners very often have problems with overloaded cable trays. One solution would be to have cabling with significantly smaller cross-sections.
Are 24 V components compatible with the 230 V control panel?
The SHEV control panel can be used to control and supply both 230 V and 24 V components. Whereas our drives are all designed for 24 V or 230 V, the weather sensors, for example, are supplied with 24 V. Using the 24 V plug-in unit in the SHEV control panel, we are able to supply the power for the weather control panel and, at the same time, supply the sun shading drive using the 230 V plug-in unit, for example. This interaction is very important for large buildings.
Are architects aware of the benefits of a 230 V smoke vent?
The level of awareness isn't where it should be yet. We would like the communication among various specialist planners to function better through comprehensive coordination. That would make the advantages visible for planners in different areas as well. In a way that the electrical planners have the advantage of lower cable costs, structural engineers benefit from lower cable cross-sections and architects can put their design ideas into practice. In our experience with the previously mentioned example structures, you can see very clearly that everyone benefits from increased collaboration between those involved.
