Palram Canopia Automatic Roof Vent Opener

The Palram – Canopia Automatic Vent Opener is designed to automatically open and close your greenhouse vent window in order to help control the temperature and humidity levels inside your greenhouse. This process provides additional ventilation for all Palram – Canopia Greenhouses, making gardening more efficient and affective. As the air inside the greenhouse warms, the Automatic Vent Opener will cause the vent to gradually open to allow the correct amount of airflow into the greenhouse until the optimal temperature is reached. This functionality will also assist to release excess heat when the temperature in the greenhouse gets too warm.The Automatic Vent Opener will start to open the vent window around 60 degrees Fahrenheit and as the temperature continues to warm the vent will open more fully. When the air begins to cool the Automatic Vent Opener will allow the vent to gradually close in order to trap the warmer air inside your greenhouse. The vent arm was designed with the use of wax that expands with heat and contracts when it cools. The Automatic Vent Opener conveniently operates without the use of electricity. The automatic vent opener can easily be installed on any roof vent of your Palram – Canopia greenhouse.
