Automatic Vent Opener for greenhouse
1) Maximum load: 7 kg - most panes greenhouses do not exceed this weight;
2) Adjustment of the temperature: from 15 to 25 ° C;
3) Shipping Weight: 0.5 kg
Based on termotsilindr in which liquid greatly expands or shrinks depending on the temperature.
In the sun, the temperature increases in a hothouse, termotsilindr located there in is heated, the fluid pushes the piston and the piston, in turn, opens the window.
At sunset and a decrease in temperature in the greenhouse in termotsilindre fluid is compressed, and the ventilator closes under its own weight.
Thus pane rises to 45 centimeters.
This system enables automatic ventilation greenhouses begin airing a temperature of 16 °, and 25 °.
The maximum length of the stem rises at 30 ° C.

Based on thermostat in which liquid greatly expands or shrinks depending on the temperature.
In the sun, the temperature increases in a hothouse, thermostat located there in is heated,
the fluid pushes the piston and the piston, in turn, opens the window.
At sunset and a decrease in temperature in the greenhouse in thermostat fluid is compressed,
and the ventilator closes under its own weight.
Thus pane rises to 45 centimeters.
This system enables automatic ventilation greenhouses begin airing a temperature of 16 °,and 25 °.
