Greenhouses and cattle buildings integrate systems of aeration and ventilation today the purpose of which is to master the internal weather conditions - our systems allow the opening of sides and roof and consist of mechanical elements associated to electric elements of command and regulation
The main solutions of aeration:
Aeration by continuous ridge vent.
A fixed winch opens the roof or the sides (shutter, guillotine) by activating a command tube which pulls racks fixed to the continuous ridge vent.
Winding ventilation with telescopic arm.
A fixed winch rolls up or unwinds the plastic on all the side length through a telescopic arm.
Aeration by gravity, continuous ridge vent falling.
A winch activating a command tube fixed at the top of the continuous ridge vent rolls up or unwinds the plastic through pulleys and cables.
Spreading width ventilation.
A winch activates a cable fixed to the walls of the greenhouse which rulls out or moves closer every joint of plastic with retractors.
Thermal screening - shading
A winch activates a horizontal screen which insures or a heat insulation (thermal screening) or a regulation of the luminosity (shading).
