Building services use drive systems for ventilation dampers, smoke extraction openings, facade elements and gates that have to function reliably and with low maintenance for decades. Fire protection applications such as smoke extraction systems also require proven functional safety in an emergency. Standards and regulations place additional requirements on the components used.
In addition to operational safety, quiet operation and a compact design are important criteria, especially in prestigious buildings or sensitive environments. Architects and planners need solutions that can be integrated seamlessly into facade and roof constructions.
WMH Herion supplies screw jacks and rack and pinion drives for ventilation and smoke extraction systems in buildings. The self-locking versions of the screw jacks are particularly suitable for applications in which the damper position must be maintained even during a power failure.
For facade drives and large louvre systems, WMH Herion offers racks in various lengths and modules that can be easily integrated into existing constructions. The stock programme ensures that spare parts can be procured quickly, even for older installations.
For building services, WMH Herion supplies screw jacks with a lead screw for dampers and slide gates, racks for facade drives and quiet bevel gear units for angular transmissions. All products are designed for compact installation and low-maintenance operation.
WMH Herion supplies complete drive assemblies for ventilation dampers, smoke extraction systems and facade drives, delivered ready for installation and function-tested. The systems can be adapted to various motor types and control concepts.
What distinguishes WMH Herion as a partner?
Building services applications, from ventilation and lifts through to gate drives, require drive components that run quietly, are compact in design and function reliably over long maintenance intervals. WMH Herion supplies spur gears, worm gear units and couplings from a broad standard range with more than 12,000 items as well as custom-made solutions for specific installation situations.
As a manufacturer and systems supplier, WMH Herion answers technical questions directly, without intermediate steps. This saves time in project planning and gives you certainty when selecting components. ISO 9001 certified, proven in building services and in more than 40 further industrial sectors.
Which drive components are suitable for smoke extraction dampers?
For smoke extraction dampers, self-locking screw jacks are recommended, as they hold the damper position safely even during a power failure. WMH Herion supplies them in various lifting force classes, on request with a spring return function for fail-open or fail-close versions.
Are rack and pinion drives available for large facade openings?
Yes. WMH Herion supplies racks in lengths of up to several metres as well as matching pinions and gear units for facade and ventilation drives. The components can be made to measure and prepared for direct installation.
Does WMH Herion also supply complete assemblies?
Yes. In addition to individual components, we offer assembled handling axes and complex multi-axis systems, fully assembled, tested and ready for use.
How quickly are standard items available?
Most items from the stock programme are available immediately and are delivered within a few working days. For custom-made solutions, we discuss the delivery time individually.
