Folding Arm²

The folding arm is the premium actuator technology for electromotive window opening on facades and roofs as well as for door opening and the automated opening of swing sashes. Folding arm actuators are not only designed and tested for use in smoke and heat ventilation, but also for controlled natural ventilation. They have a special kinematics and their high performance gear (> 20.000 LW) in combination with the stainless steel lever arms is very resistant to changing loads (wind, snow). Especially the symmetrical design and, when closed, the small installation dimensions make this automatic window opener ideal for projects with high aesthetic demands - especially for large and heavy windows. All folding arm actuators are tested and certified according to EN 12101-2 together with various profile series for use as natural smoke and heat exhaust ventilation devices. Parameters such as opening stroke and force can be parameterised via a programming interface and further status messages can be read out.

EA series folding arm actuators are available as solo actuators and as tandem actuators for parallel operation. The products of the PA series are available in different versions as solo and synchronous drives. They can be networked with each other in synchronous groups as well as for remote control with SHEV control panels and building management systems. All folding arm² actuators are characterised by a very high efficiency for low power consumption and thus reduce ongoing operating costs.
