Automatic Louver Opener
The Automatic Louver Side Window Opener is designed to automatically control the temperature and provide additional ventilation in Palram – Canopia Greenhouses equipped with a side louvre window. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the optimal temperature is reached. The vent arm was designed with the use of wax that expands with heat to push a piston, which opens the louvre window, as the air gets warmer, then contracts as it cools, closing with the use of a spring. The Automatic Louvre Opener operates without the use of electricity.
