louver window opener Manufacturers and Suppliers

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.

I paired this Liberty Automatic Louver Window Opener with an Exaco Trading G7014 Louvre Window for Bio-Star Pioneer Greenhouses into my home-built greenhouse (both purchased through Amazon). I didn't install it til December and in Kentucky 2013 it was already cold. We did have a couple warm days where I was able to see it operate; and this necessitated adjustments. Since my greenhouse was created by myself I had to create my own vent window, so much of my tweaking of the automatic opener was due to trying to get the window vent correctly framed in my greenhouse design. It wasn't until we had a couple "Polar Vortexes" weather patterns in our area that I got the opener to properly orchestrate the opening and closing of the vent blades in the window. Of course it was cold for so long that I didn't get to see the automatic opener in action until a rare "warmer" February day. It is now early April and I can see the opener\vent is working "as advertised". I can hear the springs adjusting the vents as I work outside in my back yard on some raised beds I am constructing. It's a good sound. So far this automatic window vent opener is doing great! I hope it continues to do so!
