D+H Chain Drive KA 34
Robust 300 N SHEV chain drive for mounted installation
Extremely robust, durable and reliable, the KA 34 is a proven D+H SHEV chain drive with 300 N force for mounted installation.
It can be used in a wide range of applications thanks to multiple bracket solutions and is suitable for both smoke exhaust and daily ventilation systems.
Features
- Can be used for smoke exhaust openings in accordance with EN 12101-2 and for daily ventilation.
- Motor electronics controlled by microprocessor.
- High-speed function (HS) for especially fast opening in case of fire.
- Special chain stabilisation.
- Pressure applications up to 700 mm, with tension stroke lengths over 1000 mm possible.
- Relief of pressure on the window gasket after the closing process.
- Programmable drive functions and variable drive parameters.
- Reduced speed in CLOSED direction to 5 mm/s for passive closing edge protection.
- Time-controlled reversing when an obstacle is detected in CLOSED direction for active closing edge protection.
