Product Description

Compatible with any Palram Canopia greenhouse roof vent, the Palram Canopia Greenhouse Auto Vent Arm helps optimise the temperature in your greenhouse, even when you’re not around.This intelligently-designed greenhouse auto vent arm opens and closes the roof vent according to the temperature inside your greenhouse. It operates using a solar-powered mechanical system, so there’s no need to connect to an electricity supply for it to work.The heat-activated arm is designed using wax, which contracts and expands as the temperature inside the greenhouse changes. The arm begins opening the roof vent at 12-15C, and then closes it as the temperature falls.Simple to instal, this greenhouse automatic vent arm is compatible with any Palram Canopia greenhouse that is fitted with a roof vent.Free delivery is available to most UK postcodes.Solar-powered mechanical systemNo need for electricityAutomatically opens the roof vent at a temperature of 12-15CCloses the vent as the temperature fallsSimple installationCompatible with any Palram Canopia greenhouse roof ventFree delivery to most UK postcodes
