Easy to fit - Designed specifically to fit the Rion Louvre Window.

Automated - Automatically opens the louvre window, it also has a release catch allowing you to manually open and close the louvre window if required.

Operation - The unit works by having a special mineral wax within the cylinder. This wax is very sensitive to temerature and expands with heat, pushing out a piston rod to actuate the opening arm on the louvre window. As the temperature falls the wax contracts and the window closes.

Actuation range - The opener can be adjusted to set the opening temperature between 15*C up to 25*C.
