This Automatic Louvre Opener for the Rion greenhouse will open and close depending on the temperature. This makes it easy for you to ensure good air circulation throughout your greenhouse even when you're not at home. • Easy to fit to the Rion Louvre Window • Designed to automatically open the louvre, it also has a release catch allowing you to manually open and close the louvre window if required • It works by the cylinder within the opener being full of a mineral wax. This wax expands with heat, pusing a piston and opening the louvre. as the temperature falls the wax contracts and the window closes.
