Automatic Roof Vent Arm Opener / Automatic Climate Control for Palram Greenhouses ONLY

The 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 air flow 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 Palram Greenhouse models only. Opens roof vent automatically as temperature warms for air circulation and heat relief, closes when temperature cools. Mechanic system, solar powered – start opening point: 12-15C (53.6-59F). Easy to install Suitable for all Palram greenhouses.

  • Works with all Palram-Canopia Models
  • Opens vent window automatically at warm temperature for air circulation and heat relief, closes when temperature cools
  • Automatically responds to weather changes
  • Opening temperature can be adjusted for specific needs
  • Mechanic system – no electricity is needed
  • Auto Opener Roof is Temperature activated by a thermally powered piston so no batteries or motors to fail
  • One opener required for each roof vent

Automatic Roof Vent Arm Opener

The Palram Automatic Vent Opener is designed to automatically open and close greenhouse vents, helping regulate the temperature and humidity inside the greenhouse without the need for electricity or manual intervention. Here's how it works:

  1. Thermal Expansion Mechanism: The vent opener contains a cylinder filled with a special wax that expands and contracts with temperature changes. When the temperature inside the greenhouse rises, the wax expands.

  2. Opening the Vent: As the wax expands, it pushes a piston, which moves a lever or arm that opens the vent. This allows hot air to escape and cooler air to enter, helping to lower the temperature inside the greenhouse.

  3. Closing the Vent: When the temperature drops, the wax contracts, pulling the piston back into the cylinder. This action retracts the lever or arm, closing the vent and helping to retain heat inside the greenhouse.

  4. Adjustable Temperature Settings: Many Palram vent openers allow you to adjust the temperature at which the vent begins to open. The typical temperature range for these adjustments is between 15°C (59°F) and 25°C (77°F). This is usually done by turning a screw or knob on the device, allowing you to set the optimal temperature range for your specific greenhouse needs.

  5. No Electricity Required: The vent opener operates purely on the principle of thermal expansion and does not require any electricity, making it a reliable and energy-efficient solution for greenhouse ventilation.

The automatic operation ensures that your plants receive the optimal growing conditions without constant manual adjustments, contributing to a more consistent and productive growing environment.
