Ouverture automatique de lucarne Univent pour serre - Aluminium noir anti-corrosion avec double ressort - Juliana

Expert Insight on Juliana's Univent Automatic Vent Opener

Ensuring proper ventilation within your greenhouse is crucial for the health of your plants. To facilitate this, we recommend the use of automatic vent openers that will activate to open your roof vents when the internal temperature gets too high, and close them as it cools down.

The Univent automatic vent opener by Juliana is particularly suited for polycarbonate greenhouses. Given that polycarbonate is lightweight, its mass alone is insufficient to retract the piston. The dual springs ensure the vent is pulled shut for a complete closure. This automatic window opener maintains an optimal temperature for your plants to thrive.

Made from anti-corrosion treated aluminum with dual springs, this opener ensures a full closure of the vent without relying on the vent's weight and includes an Easyclip system. It's a versatile system that can be applied to windows, sliding doors, side windows, and mini greenhouses.

The temperature can be adjusted by rotating a cylinder between 17 and 25 degrees Celsius. It allows for a maximum opening of about 45 cm and can exert a force of 7 kg, equivalent to lifting a 15 kg window. In the event of strong winds, the opener can be easily disengaged using the 'easyclip' system.
