Dual Spring Mechanism: Delivers robust thrust force and stability for reliable window operation in standard settings or exposed mountainous locations with strong winds.
for Solar Thermal Activation: Uses solar energy and a gas-filled cylinder that expands with heat to automatically open and close between 15°C-25°C (60°F-77°F), enabling passive climate control in greenhouses. Aluminum Construction: Built from LONGLASTING aluminum alloy with a protective black coating to withstand rain, UV exposure, and temperature extremes year after year.
Precise Temperature-Driven Operation: Opens gradually as ambient temperature rises within the calibrated range, helping maintain consistent internal conditions perfect for , herbs, and delicate greenhouse plants.
general Mounting Compatibility: Includes adjustable clamps and mounting hardware designed to fit most standard greenhouse window frames-check your specific window dimensions before installation.
