Natural ventilation is implemented by windows, dampers or skylight domes. The dampers are opened and closed manually (by hand) or automatically (by electric drive).
Only automated natural ventilation offers such advanced options as automatic opening and closing based on time, the quality of the air in the room, temperature, and humidity.
Drives, commonly also referred to as motors, make it possible to open and close windows electrically. Drives fall into the two main categories of 230 V AC and 24 V DC solutions.
230 V solutions can be seamlessly controlled via the building’s own 230 V power supply. 24 V solutions offer the added benefit of working well together with smoke and heat exhaust systems as they can also be operated with batteries (battery packs), making them suitable for operation in emergency power mode. HAUTAU’s portfolio includes solutions for both of these operating voltages. The following HAUTAU products can be incorporated into window automation systems:
Each drive offers its own unique advantages that vary with the type of the window and the weight of the window as well as with the desired opening width. As part of their automated and manual control range HAUTAU offers the following products capable of providing natural ventilation when used in combination with a building automation system:
