Chain Actuators

Compact, compared to linear actuator alternatives Easy to install and maintain Come in a wide variety of options, stroke lengths and colours Low noise output Low power usage Low cost Reliable and flexible solution Synchronised versions are available

Available in single and double chain variations, the chain is designed to engage with pinions that mounted on a drive shaft that is inside an external casing. As the pinions spin, the chains links rotate through the casing at a 90-degree angle which directs the chain into a rigid, straight form, highly resistant to compression and tension. As the chain is directed into a straight form, the window pushes open and as it retracts into the casing, it causes the window to close.

An electric chain actuator can be used to open and close windows for smoke and natural ventilation. These help with daily ventilation and in cases of emergency as an active fire protection method to help control smoke.

Electric chain actuators open and close windows for the purpose of natural ventilation, smoke control and heat management. They have a chain that extends from the housing of the actuator which connects with the moving sash of the window or vent, pushing it open or closed.
