Automatic Louvre Opener
From: Greenhouse Fans, Louvres, Vent Openers and Shading : Louvres
This Automatic Louvre Opener, opens and closes your Louvre Window as the temperature changes - making sure your greenhouse does not overheat whilst you are at work or away on holiday.
- Corrosion Resistant - this Louvre Opener has an attractive black powder coated body and is corrosion resistant throughout.
- How It Works - the stainless steel cylinder contains a mineral wax which expands with heat, causing the louvre vent to open. As the temperature falls the wax contracts, closing the louvre.
- Opening Temperature Range - adjustable between 15 - 25*C / 59-77*F
- Release Catch - allows the manual opening and closing of the louvre irrespective of the greenhouse temperature.
