  1. Automatic vent opener

    Posted by Unknown on 16th Apr 2020

    Works great and installation was easy
    Our greenhouse when sunny gets into the 100° range if we are not around to open door to cool it off. This does the job of keeping temps lower.

Palram - Canopia | Automatic Vent opener - Greenhouse Accessory 00:44

Palram - Canopia | Automatic Vent Opener was designed to automatically control the temperature and humidity levels and provide additional ventilation when needed, making gardening easier. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of airflow into the greenhouse and closes when the temperature cools. The vent arm was designed with a metal cylinder containing wax which expands when heated to push a piston, which raises the window, as the air gets warmer, then contracts as it cools, closing with the use of a spring and resetting the piston. All you need to do is to install it on your roof vent window and it automatically starts working. The Automatic Vent Opener operates without the use of electricity and is compatible with all PPalram - Canopia | greenhouse models only. • Opens roof vent automatically as the temperature warms for air circulation and heat relief, closes when the temperature cools • Mechanic system, solar-powered - start opening point: 12°-15°C • Easy to install • Suitable for all Palram - Canopia |greenhouses Follow Canopia by Palram: Website: Facebook: Twitter: Instagram: Pinterest: Linkedin: #palram#canopia#canopiabypalram#palramcanopia#canopiapalram
