Construction and operation

The system rolls up from the bottom, allowing air to enter from below. The system is controlled from the centre of the opening, using a sliding cardan shaft. This system is often used in poultry and pig farming. Thanks to the system’s multifunctionality, it is also suitable for many other applications. 

The system is mounted to the existing structure in its entirety, requiring only 10cm at the top and 15cm at the bottom. 


Depending on preference, the Poly System can be operated manually (crank) or motorized.


Safe operation of our systems is extremely important to us. That’s why you may only connect a climate computer if the system is mounted 2.70 m from the ground or higher.  If this is not the case, you can install bird mesh in front of the system. If a system has been automated, for example with a remote control or climate computer, we recommend installing a windbreak mesh in front of the revolving reel for the sake of safety. This helps reduce the risk of accidents.
