Opening greenhouses: the advantages of technology

Benefits of opening elements

The basis of the opening elements of greenhouses is a cylinder with hydraulics. When the temperature rises in the greenhouse, the oil in the cylinder heats up and expands, thus pushing the stem out. He lifts the sash itself and the window opens. The air in the greenhouse cools, at the moment of ventilation, the oil in the cylinder narrows again and with the help of a spring the sash slams shut. The sliding system is quite sensitive, thanks to which the greenhouse with automatic ventilation is under reliable protection from gusty winds and rains.

The temperature to which the sensor will respond is set directly by the owner. Moreover, as a rule, the temperature range is set to 16-25 degrees. The mechanism itself is quite simple, there is no need to change components, and it works by itself, that is, an electrical network is not required to connect it. In turn, such systems definitely have advantages, namely, that they are neither environmentally friendly and economical, easy to maintain, operate, reliable, and their minimum service life is ten years.

Types of automatic openers

It is very important that greenhouses have good ventilation. It is for this that special automatic methods of airing them are produced. They are divided into two main types: electric and hydraulic. Of course, if you install an automatic window on the roof of the greenhouse, it will be just wonderful, since the regulation of temperature regimes will be as accurate as possible. But in this case, the owner needs to answer for himself first of all two questions regarding the readiness to install such equipment, since it costs a lot.

Also, does it make sense to conduct electricity to the greenhouse in order to automate ventilation. Or is it still worth thinking of something else that you can do even with your own hands. Hence the conclusion that hydraulics is the best option, and it is quite popular among gardeners and gardeners.

Hydraulic openers

Each such system has its own specific nuances, depending on which the final choice is made. To choose one or another system, it is important to know some of the nuances of automated devices for your “nurses”:

1. Find out their weight. You first need to know where you will install them and to which part of the “nurse” you will attach. It is important that that section can withstand the weight of the automatic system.
2. Pay attention to how much weight it is designed to lift, whether it is suitable for windows or for window vents in the roof. As a rule, they are designed to lift five to seven kilograms, which is generally enough to automatically open the greenhouse window.
3. Price. Many, having learned how much good, high-quality systems cost, decide to do their own ventilation.
4. Depending on the model of the device, the temperature regime can be set in different ranges. It is very convenient when the temperature can be chosen from and to. Therefore, it is worth familiarizing yourself with this characteristic before buying.
5. It is important to know in advance at what angle exactly the window, door or window in the greenhouse opens. This is a very important indicator, and it must be indicated on the automatic systems.

Be sure to assess the situation with the winds in the area. If they blow gusty and in different directions, install an anti-hurricane stall system.

When you think over the nurse’s ventilation system, having “walked through” the above points, and make a purchase decision, you can go to the store.

In this video, you can hear an explanation of what a device for opening windows in greenhouses is and why it is needed.

Which option to choose?

In stores, you can choose an automatic system among those offered. If you have confidence in domestic manufacturers, then you can save money and purchase an automatic opener for greenhouses Dusya-Sun, UFOPAR, Tuymazy, as well as an automatic thermal drive to open doors. Such systems are simple and convenient, as well as reliable and have a long service life.

As for the automatic sliding greenhouse systems of imported production, they cost much more, sometimes several times, compared to domestic systems. Among those, there are very good systems made in Denmark – Gigavent, Megavent; England – Autovent XL, Autovent MK 7, Super Autovent MK 7. If the owner has a very large farm, then you should still think about purchasing imported systems for wet nurses with an opening top.

Installation of the device in the greenhouse

When you have purchased a system – an automatic window opener installed on the roof of a greenhouse, etc., you need to learn how to install it correctly. There is absolutely nothing difficult in this process, but you still need to read the instructions (after all, it describes in detail regarding the installation of the system in the nurse), and also follow some recommendations:

1. Think over exactly where the opening windows will be located (on the sides of the nurse, as well as on her roof). When constructing a greenhouse, it is necessary to think over the ventilation system (windows and vents) in advance. It is important that those parts that open are on the roof, on the side where strong winds blow.
2. The system of Danish production – Megavents, is installed directly on the window itself, which makes it much easier to work. But the domestic UFOPAR, which weighs about four kg, is installed directly on the greenhouse frame. And regardless of the element of the greenhouse: it is a roof, or any other, it is important that it is durable and can withstand the expected load.
3. It is important that the system responds exclusively to the temperature inside the greenhouses. If you install the vending machine under a roof, protect it from direct sunlight!
4. If an anti-hurricane system is not provided and absent, it can be done independently using: chains, ropes, cords and other things.
5. Adhere to the correct operation indicated in the enclosed leaflet.
