Greenhouse automatic louver window opener fits all Rion - Palram Greenhouse models.

Opens louver window automatically at 68F for air circulation, closes when temperature cools.

The Automatic Louver Vent Opener was designed to automatically control the temperature and provide
additional ventilation. 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 minerals that expand with heat to push a piston, which raises the
window, as the air gets warmer then contracts as it cools, closing with the use of a spring. The Automatic Vent Opener operates without the use of electricity.

The opener has a metal piston containing special wax which expands when heated. This pushes and opens the window quiet and safely. As the temperature cools, the wax get shrinks. Opening and closing of the window is gradual and allowing just the right amount of air flow for cooling greenhouse space.
