Chain, rack, rod actuators.
Window frames come in various types, sizes and weights. Some are installed where atmospheric agents such as wind and snow may play an important role in the determination of the forces required to move them. This is why there are different families of automations that differ basically in their actuation system. The actuators can be Chain, Rack or Rodactuators. Sometimes the frames must be moved automatically for practicality or security reasons, using electronic control devices such as control units for detection of atmospheric events or smoke and heat exhaust ventilation systems. Before installing an actuator on the frame, it is necessary to check that the actuator is suited for the work to be carried out and, especially, that it has the desired performance characteristics.
