Product information

Description

The Univent automatic roof vent opener is a precision-engineered device designed to regulate greenhouse temperatures without the need for electrical power. By utilizing a temperature-sensitive cylinder, the mechanism automatically adjusts the opening of the roof vent as ambient conditions change. This ensures that your greenhouse maintains a consistent climate, which is essential for preventing overheating and fostering healthy plant development throughout the growing season.

Advantages

This automatic opener offers a reliable and maintenance-free solution for greenhouse climate management. Constructed from durable aluminium, it is built to withstand the humid environment of a greenhouse while providing consistent performance. Because it operates entirely on thermal expansion, it eliminates the need for batteries or mains electricity, making it an eco-friendly and cost-effective choice for any gardener. The system provides peace of mind by ensuring that ventilation occurs even when you are not present to manually adjust the windows.

Suitable for

  • Small to medium-sized hobby greenhouses
  • Greenhouses requiring passive climate control
  • Maintaining stable temperatures for sensitive plant species

When it may not be suitable

This device is not suitable for extremely heavy or large-scale commercial greenhouse vents that exceed the weight capacity of the thermal cylinder. It should also not be used in environments where the temperature is expected to drop below -3 °C during storage or operation, as this can damage the internal mechanism.

Key specifications

  • Material: Aluminium
  • Operation: Temperature-sensitive thermal expansion
  • Power source: None (mechanical)
  • Dimensions: 0.3 m length, 0.1 m width, 0.15 m height
  • Colour: Grey

How to use

Installation involves attaching the opener to the greenhouse frame and the roof vent according to the provided mechanical alignment. Once installed, the thermal cylinder reacts to the rising temperature by expanding, which pushes the vent open. As the temperature drops, the cylinder contracts, allowing the vent to close securely. No manual calibration is required for daily operation, though it is recommended to check the mounting points periodically to ensure the mechanism moves freely.

What to consider before purchase

  • Verify the weight of your greenhouse vent to ensure it is compatible with the opener.
  • Ensure the greenhouse structure allows for the mounting of an automatic opener.
  • Consider the local climate to ensure the device is not exposed to freezing temperatures during the off-season.

Usage recommendations

To ensure the longevity of the thermal cylinder, remove the device from the greenhouse during winter months if temperatures drop below -3 °C. Proper storage in a frost-free environment will prevent damage to the internal components and ensure reliable operation for the next season.
