Direct openers for daily ventilation
GEZE Electrically operated chain drives
The electrically operated chain drives have been designed for vertically installed rectangular bottom, top, horizontally pivot hung, side hung and vertically pivoted windows in dry rooms and are suited for daily room ventilation.
The drives are fitted parallel to the window and depending on the colours, harmoniously match the window design. They are equipped with a special chain which can transmit the tensile and compressive forces. In the closed position the chain is rolled up invisibly in the drive housing.
