RIGA Automatic Window Opener with Quick-Release Arm
Keep your greenhouse at the ideal growing temperature without lifting a finger. The RIGA Automatic Window Opener uses heat-activated paraffin oil technology to open and close roof or side windows automatically — no electricity, no wiring, no manual intervention required.
Engineered specifically for Riga greenhouse models, this opener is the trusted solution for hands-free ventilation that protects plants from overheating and maintains healthy air circulation year-round.
How It Works
As interior temperatures rise, paraffin oil inside the piston expands and pushes the arm open, beginning ventilation at approximately 72°F (22°C). As temperatures cool, the oil contracts and the window closes automatically — a fully passive, energy-free cycle that runs every day without any input from you.
