LEGI Automatic Opener for Roof Greenhouse Windows - Dual Spring

Product detailed description

The LEGI automatic opener for roof greenhouse windows replaces manual window opening, so you don't have to constantly think about when it's necessary to open and close the windows in the greenhouse. The opener's piston, included in the package, contains wax/oil that reacts to ambient temperature. As the temperature rises, the lever opens and the window opens accordingly. The system works in reverse when the temperature drops.

The difference between this opener and a standard roof opener lies in a different construction, thanks to which the piston of this opener does not extend beyond its structure, so there is no risk of it coming into contact with the polycarbonate in the case of a greenhouse with a large curvature. All other features of both openers are the same.

The opening start can be set within a temperature range of 17 °C to 25 °C according to the grower's needs. The upper limit for full opening is at 34 °C. The maximum total window weight for proper functioning is up to 14 kg (classic polycarbonate windows).

If your greenhouse, in addition to the roof window, also has ventilation on the front of the greenhouse (door or front window), you can also use the automatic opener for front windows. However, remember that warm air stays near the ceiling, which is why roof ventilation is very important. Front ventilation of the greenhouse can be considered rather supplementary.

Benefits of regular ventilation

Regular greenhouse ventilation is essential to ensure optimal conditions for plants, which prefer a balanced temperature with minimal temperature fluctuations. Another essential condition for an optimal harvest is regular exchange of fresh air, which affects the health and fertility of plants. In addition, ventilation also contributes to the pollination process or prevents the spread of pests and pathogenic organisms.

Advantages

• Automatic temperature regulation without grower intervention
• Works without the need for electricity
• Flexible temperature setting – e.g. according to the type of plant grown
• Top-quality workmanship
• Made in the EU

Removing the piston

If not in use for a longer period, or if temperatures drop below 7 °C, it is necessary to simply remove the piston from the opener and store it in a dry and warm place to avoid damaging its functionality. The opener's frame itself can remain attached to the greenhouse window.

Before reinstalling it, it is advisable to lubricate the inner part of the piston (e.g. with vaseline or oil) so that the rod moves smoothly inside the piston cylinder. If the piston stops working, there's no need to buy a new opener - simply purchase a replacement piston HERE.
