UCS Quasar Chain Winder Range

The UCS Quasar Chain Winder Range encompasses the 24V Quasar Chain Winder and the 24V Quasar Synchro Chain Winder. These remote window winder are ideal when looking for a larger opening for your high level windows, with the maximum stroke length being 500mm.

Both the Quasar and Quasar Synchro can be operated by the occupant using a simple wall mounted switch, any of the Arens Ventilation Controllers or a Building Management System, to provide your building with natural ventilation. If the project calls for it, the Quasar range are also suitable for use in Smoke Ventilation Systems.

Quasar Chain Winder

This heavy duty electric chain winder features a strong stainless steel, double link chain that exits from the centre of the casing, with a maximum stroke length of 500mm.

  • The Quasar chain actuator is housed in a narrow line section 47 mm × 32 mm.
  • The chain winder comes with 1.5m of cable and pivot brackets as standard.
  • Suitable for installation on Smoke and Heat Extraction Systems.
  • Available in light grey powdercoat finish

If window width is between 1200mm – 4800mm wide two or more UCS Quasar Synchro Chain actuators should be used to avoid twisting of the frame and to comply with manufacturer recommendations.

Quasar Synchro Chain Winder

  • Synchro version is equipped with an integrated speed synchronisation control board that allows the mounting a maximum of 4 Synchro Quasars Chain Winders on a single sash.
  • Should one winder stop all other synchronised winders stop immediately to ensure there is no twisting of the window.

Alternatively, the Vega Synchro Chain Winder is also appropriate for windows greater than 1200mm wide.




The Quasar DC F-Signal can also provide open and closed feedback signal (free potential, maintained contact), which is activated by the current limit detection.
