Rion Greenhouse Window Vent Opener
Replacement Accessories for Rion Modular Greenhouses
Rion Greenhouse Window Opener automatically opens and closes Roof Vents when the temperature changes. The modular nature of the Rion Greenhouse allows these accessories to be added at any time. Automatically opens and closes Roof Vent when temperature changes. The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the vent. As the temperature cools, the mineral shrinks and a spring closes the vent and resets the piston. The opening and closing of the vent is gradual allowing just the right amount of air flow for cooling.
