D+H KA34 Chain Actuator
D+H KA34 Chain Actuator – High Performance AOV & SHEV Window Drive
The D+H KA34 Chain Actuator is a powerful, high-performance window drive designed for both smoke and heat exhaust ventilation (SHEV) and daily natural ventilation applications. Certified as D+H Euro SHEV in accordance with EN 12101-2, the KA34 is ideal for Automatic Opening Vent (AOV) systems in commercial buildings, public spaces, and residential developments.
Engineered for speed, reliability, and safety, the KA34 delivers controlled, stable window movement with advanced protection features built in. Available in 500mm, 600mm, and 1000mm stroke lengths, and in both AC and DC versions, it offers flexibility for a wide range of façade and rooflight installations.
Delivery time: 1–2 weeks.
Key Benefits:
Certified for Smoke Ventilation & Daily Use. Suitable for AOV and SHEV systems in accordance with EN 12101-2, making it compliant for life-safety ventilation installations.
High-Speed Fire Opening (HS Function). Integrated High-Speed (HS) functionality ensures especially rapid window opening in the event of fire, supporting efficient smoke extraction.
Powerful & Stable Chain Technology. Special chain stabilisation ensures smooth and reliable operation, even in demanding installations. Pressure applications up to 700mm are supported, with extended tension stroke lengths exceeding 1000mm possible.
Intelligent Microprocessor Control. Motor electronics controlled via microprocessor allow programmable drive functions and adjustable operating parameters for precise system integration.
Advanced Safety Protection:
- Passive closing edge protection – closing speed reduces to 5 mm/s.
- Active closing edge protection – automatic reversing if an obstacle is detected.
Protects Window Seals. Integrated pressure relief after closing reduces long-term strain on window gaskets, improving durability.
Key Features:
- Suitable for AOV & SHEV smoke ventilation
- EN 12101-2 compliant (Euro SHEV)
- Stroke options: 500mm, 600mm, 1000mm
- Available in AC or DC versions
- High-Speed (HS) fire opening function
- Microprocessor-controlled motor electronics
- Special chain stabilisation
- Programmable parameters
- Passive & active closing edge protection
Applications:
Ideal for:
- Automatic Opening Vent (AOV) systems
- Smoke and heat exhaust ventilation (SHEV)
- Commercial façade windows
- Rooflights and high-level ventilation
- Public buildings, schools, offices and residential developments
Compliance Guidance
Ensure AOV windows requiring actuators are tested in accordance with BS EN 12101-2 and carry the necessary CE mark. Window manufacturers should confirm compatibility with the D+H actuator range as part of certification.
