Palram – Canopia Automatic Roof Vent Opener
The Palram – Canopia Automatic Roof Vent Opener is designed to automatically control the temperature in all Palram – Canopia Greenhouses. As the air in the greenhouse warms, the vent gradually opens to allow the right amount of air flow into the greenhouse and shuts when the optimal temperature is attained. The vent arm is designed with the use of natural wax that expands as the air gets hotter, to push a piston which raises the window, then contracts as it cools, closing with the aid of a spring. It operates without the use of electricity.
