How to make opening greenhouses yourself

Benefits of opening elements
The basis of the opening elements of the 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 raises the sash itself and the window opens. The air in the greenhouse is cooled, at the moment of airing, the oil in the cylinder narrows again and with the help of a spring the sash slams shut. The sliding system is quite sensitive, so that the greenhouse with automatic ventilation is protected from gusty winds and rains.
The temperature to which the sensor will react is set directly by the owner. Moreover, as a rule, the temperature range is set at 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 there is good ventilation in greenhouses. It is for this that special automatic methods of airing them are made. They are divided into two main types: electrical and hydraulic. Of course, if you install an automatic window on the roof of the greenhouse, it will be just great, since the temperature control will be as accurate as possible. But in this case, the owner needs for himself first of all to answer two questions about the readiness of the installation of 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 coming up with something else that you can do even with your own hands. Hence the conclusion that hydraulics is the best option, and quite well-liked among gardeners and gardeners.
Hydraulic openers
Each such system has its own specific nuances, depending on which the final choice is made. To choose this or that system, it is important to know some of the nuances of automated devices for your “nurses”:
- Know their weight. First you need to know where you will install them and to which part of the "wet nurse" you will attach. It is important that that section can support the weight of the automatic system.
- Pay attention to the lifting of what weight it is calculated, whether it is suitable for windows or for vents in the roof. As a rule, they are designed to lift five to seven kilograms, which is generally enough for the greenhouse window to open automatically.
- Price.Many, having learned how much good, high-quality systems cost, decide to do airing with their own hands.
- 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 selected from and to. Therefore, it is worth familiarizing yourself with this characteristic before purchasing.
- It is important to know in advance at what angle the window, door or window in the greenhouse opens exactly. This is a very important indicator, and it must be indicated on automaton systems.
It is imperative to evaluate the situation with the winds in the area. If they blow impetuously and in different directions, install an anti-hurricane stall system.
When you think over the system for ventilating the nurse, "going through" the above points, and decide to buy, you can go to the store.

In this video, you can hear explanations about what a device for opening windows in greenhouses is and why it is needed.
Which option should you choose?
In stores, you can pick up an automatic system among those offered. If you have confidence in domestic producers, then you can save money and buy an automatic opener for greenhouses Dusya-Sun, UFOPAR, Tuymazy, as well as a thermal actuator to open doors. Such systems are simple and convenient, as well as reliable and have a long service life.
As for the imported automatic sliding greenhouse systems, 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 nurses with an opening top.
Installation of the device in the greenhouse
When you purchased a system - an automatic vents 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 is described in detail regarding the installation of the system in the nurse), and also adhere to some recommendations:
- Think about where exactly the opening vents 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 the parts that open are on the roof, on the side from which strong winds blow.
- The Danish-made system - Megavents, is installed directly on the window itself, which makes it much easier to work. But the domestic UFOPAR weight, which is 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 be strong and withstand the intended load.
- It is important that the system only reacts to the temperature inside the greenhouses. If you install the vending machine under a roof, protect it from direct sunlight!
- If an anti-hurricane system is not provided and is absent, it can be done independently with the help of: chains, ropes, cords and other things.
- Adhere to the correct handling as indicated on the enclosed insert.
