Wax Filled Piston In The Greenhouse Ventilation System Opener

Inside the automatic greenhouse opener is a wax filled piston cylinder containing a special wax and oil mixture. As the greenhouse warms, the wax expands and pushes a piston rod outward. This movement drives the arm that opens the window. When the temperature falls, the wax solidifies and contracts, pulling the piston back in. Springs or the weight of the window then close it, creating a self-regulating ventilation cycle.
