KA 66-TW Twin Chain Drive (24v)

Performance Features:

• KA twin has 2 chain drives in a single housing for extra wide or heavy sashes, provides double the pushing / pulling force.
• Engineered for high-performance applications, offering greater push/pull forces and extreme durability for heavier New Zealand window and roof light systems.
• Compatible with awning, casement, and hopper windows, specialised skylights and operable roofs common in residential and commercial designs.
• Universal mounting brackets, for compatibility with commonly used New Zealand joinery suites including face fix or sill mounted applications, providing solutions for both retrofit and new build projects.
• Intelligent synchronisation with BSY+ motor electronics, allows drives to work in tandem on a single large or heavy window frame.
• Programable chain stroke lengths, allowing installers to limit openings for safety (e.g., falling from height applications) or maximize openings for airflow.
• Anti-pinch protection prevents injury or damage if an object is detected in the window’s closing path, crucial for school and public sector projects.
• KA actuators are tested to EN 12101-2 standards, which are recognised under New Zealand building solutions for natural smoke and heat exhaust.
• In fire applications, the drives feature a “High Speed” mode to reach the full opening stroke in under 60 seconds, rapidly clearing toxic gases.
• W x H x D: 997-1347mm x 40 x 51mm
