UCS Quasar L Chain Winder

The Quasar L provides the greatest stroke length in the Arens Electric Window Winder Range. The two longest chain lengths, 750mm and 1000mm, should only be used for the remote control of bottom hung windows.

It 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. The Quasar L Window Chain Winder is also suitable for use in smoke ventilation systems.

This heavy duty chain winder features a strong, stainless steel, double link chain that exits from the centre of the casing.

  • The Quasar L chain winder is housed in a narrow line section – 37 mm × 72 mm
  • Available with 3 different strokes 600 mm, 750 mm or 1000 mm (750 mm and 1000 mm are only for bottom hung windows)
  • The chain winder comes with 1.5 m of cable and pivot brackets as standard
  • Available in anotec silver grey powdercoat finish
  • Available ex stock in 24 VDC

If the window is greater than 1200mm wide the UCS Vega Synchro Chain Winder (with built in synchronisers) may be more suitable. This will allow for two points of attachment to prevent bending and twisting of the window frame from occurring and meet manufacturer recommendations.




The Quasar L DC F-Signal is available with open and closed feedback signal (free potential, maintained contact), which is activated by the current limit
