The Rion Automatic Roof Vent Opener was designed to automatically control the temperature in all Rion Greenhouses. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of airflow into the greenhouse and closes when the optimal temperature is reached. The vent arm was designed with the use of natural wax that expands, as the air gets warmer, to push a piston that raises the window, then contracts as it cools, closing with the use of a spring. The Automatic Vent Opener operates without the use of electricity.
