Description
D+H KA Chain Drive – 24V Window Actuator (800mm Stroke)
The D+H KA Chain Drive 24V (800mm stroke) is a powerful, high-performance electric window actuator designed for both smoke ventilation (SHEV) and daily natural ventilation applications. Certified as D+H Euro SHEV in accordance with EN 12101-2, this chain drive is suitable for life-safety AOV systems as well as everyday façade and roof window automation.
Engineered for reliability, speed, and precision, the KA series actuator delivers smooth, controlled window movement with advanced safety features built in. Its extended 800mm stroke makes it ideal for larger ventilation openings where dependable performance is critical.
Key Benefits
Certified for Smoke & Natural Ventilation - Suitable for AOV and SHEV systems in compliance with EN 12101-2, making it ideal for commercial buildings, public spaces, and high-spec ventilation projects.
High-Speed Fire Opening (HS Function) - The integrated High-Speed (HS) function enables especially fast window opening in the event of fire, supporting rapid smoke extraction.
Powerful & Stable Chain Performance - Special chain stabilisation ensures smooth operation, even in demanding installations. Pressure applications up to 700mm are supported, with extended tension stroke configurations available.
Intelligent Microprocessor Control - Motor electronics are controlled via microprocessor, delivering accurate positioning, programmable functions, and adjustable operating parameters.
Advanced Safety Protection
- Passive closing edge protection reduces closing speed to 5 mm/s.
- Active closing edge protection reverses automatically if an obstacle is detected during closing.
Protects Window Seals - Built-in pressure relief after closing reduces stress on window gaskets, improving long-term durability.
