Make greenhouse ventilation easier with this automatic window opener that works without electricity. Thanks to the temperature-controlled piston, the window opens and closes on its own according to the current temperature, ensuring an optimal climate for plants. Easy installation and compatibility with most polycarbonate greenhouses with a gable roof.

The automatic greenhouse window opener provides reliable, convenient ventilation without constant supervision. The cylinder is filled with hydraulic oil that expands when heated and extends the piston—this opens the window. When it cools, the fluid contracts and the springs safely close the window.

It starts operating at temperatures of 15–25 °C, with maximum opening reached at 38 °C. The opener can handle a window weighing up to 7 kg and provides an opening range up to 45 cm. Installation is quick using clips or screws, and no batteries or electricity are required.

  • Automatic ventilation based on temperature for healthy plant growth
  • Maintenance-free operation with no power supply
  • Easy installation and broad compatibility with gable polycarbonate greenhouses
  • Reliable piston—keep the piston clean for smooth operation and proper window sealing
