Product Description

How do they Work?

When the greenhouse heats up to temperatures of 18-25°C, the wax expands and pushes up a stainless steel piston that opens the vent slowly.
The hotter the room temperature, the wider the vents will open.
Same in reverse, as the temperatures drop, the wax contracts and closes the vent accordingly.
