GEZE E 250 NT 24V spindle drive - suitable for protected outdoor areas

THE OUTDOOR DRIVE - GEZE E 250 NT spindle drive

The drive promises stability in outdoor areas with on-site weather protection

Drive in a compact design with a wide range of applications

With the GEZE E 250 NT, windows in façade and roof areas as well as skylight domes can be opened and closed using an electric motor. The drive stroke (stroke variants 100 - 1000 mm) is infinitely adjustable. Individual speeds can be set for the ventilation mode. The speed is programmed here on site before dispatch using special software. |-|Due to its small dimensions and technically sophisticated detailed solutions, such as the internal cable routing and the integrated, intelligent control unit, it is the ideal drive for the direct opening of SHEV windows. The integrated Syncro module makes it possible to use up to 3 drives without an external control unit. The drive is equipped with a DIP switch to change the operating mode (solo/syncro, master/slave). The spindle drive in Syncro version can be attached directly to the secondary closing edge using the swivel bracket. In contrast to an attachment with a comparable stroke on the main closing edge of the roof window, this achieves an increased opening width.

Area of application

• Smoke and heat extraction system (SHEVS) and natural ventilation (24 V) for direct opening in facades and roof areas
• Inward and outward opening windows with bottom-hung, top-hung or side-hung sashes as well as roof windows
• Use in exhaust air and supply air systems
• E 250 NT for dry rooms only, variant E 250 NT AB for protected outdoor areas (e.g. canopies)
• Installation on wooden, plastic or metal windows
