Opener ensures fully automatic opening and closing of your louver window according to the surrounding temperature.
You don’t have to worry about your greenhouse temperature or your plants to wilt or damage, from extra heat or cold, you don’t have to worry about opening and closing the greenhouse vent, the Automatic Louver opener Just makes gardening easier.
Automatically opens and closes the louver window when temperature changes. Opening temperature range adjustable between 15°C and 25°C (59°F and 77°F). The opener has a metal cylinder containing special material which expands when heated. This pushes a piston that opens the window. As the temperature cools, the material shrinks and a spring closes the vent and resets the piston. The opening and closing of the window is gradual allowing just the right amount of air flow for cooling.
