Automatic Roof Vent Opener
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 air flow 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
which raises the window, then contracts as it cools, closing with
the use of a spring.
