The Automatic Vent Opener was made to automatically control the temperature and humidity amounts and provide additional ventilation when needed, making gardening easier. As the atmosphere within the greenhouse warms, the vent gradually opens to enable the right amount of air flow into the greenhouse and closes when the temperature cools. The vent arm was designed with a steel cylinder containing wax which expands when heated to force a piston, which raises the window, as the air flow gets warmer, then contracts as it cools, closing with the usage of a spring and resetting the piston. All you have to to do is definitely to install it on your roof vent windows and it instantly starts operating. The Automatic Vent Opener operates without the use of electricity and works with with all Palram greenhouse models only. The solar driven Vent Opener will start to open as temperatures within your greenhouse reach 68 degrees F with full-open at 80 degrees. It installs efficiently and can provide care-free ventilation.
Ingenious temperature-sensitive device that automatically opens and closes coldframe lids, greenhouse windows and actually skylights. Works throughout the day and maintain a continuous interior climate, something impossible to accomplish by manual adjustments.
