Arens Compact Chain Actuator

The Arens Compact Electric Chain Winder is a 24V operator that is commonly used for the automation of  high level commercial and residential windows.

Providing a high level of flexibility and reliability, it is commonly used in many natural ventilation systems. It can allow for occupant control, partially or fully controlled natural ventilation, when used in conjunction with the Arens Ventilation Controllers, or even integrated with a Building Management System.

Combining quiet and smooth operation with a slimline design, it provides minimal aesthetic interruption for occupants.

If your windows are over 1200mm wide, we recommend our 24 V Vega Synchro Actuator (with built-in synchronisers) to allow for two points of attachment to help prevent bending and twisting of the window frame and comply with manufacturers recommendations.
