Automatic machine for greenhouses, Kharkov region.

Automatic machine hydraulic is intended for optimization of the temperature regime in the greenhouse by means of ventilation depending on the outdoor temperature and sunshine of the day. Thus, in the heat, the window of the greenhouse opens wide, and this is a guarantee: there will be no overheating. The rest of the time, the machine opens the window as needed, ensuring a moderately warm and humid climate inside the greenhouse.
The hydraulic automat for ventilating greenhouses automatically opens/closes the window in your greenhouse when it reaches the ideal temperature for plant growth.
Work is carried out in automatic mode without additional sources of electricity.
The principle of operation is based on the heating of the working fluid in the thermal cylinder by the sun. The liquid pushes out the piston. The piston opens the window of your greenhouse. As the sun sets, the temperature in the greenhouse drops, the window will close.
The increase in temperature in the greenhouse is performed by moving the lower bracket of the hydraulic cylinder down.
Installation is simple and can be done independently.(//tractor-service.com)

Technical characteristics
The weight is about 3 kg and the force on the rod is about 100 kg. This is quite enough to open a glass frame with an area of ​​about 2 square meters, or a film (plastic) frame of about 5 square meters, that is, to ventilate a greenhouse with an area of ​​10-20 square meters.
In morelarge greenhouses it is possible to simply make several frames.
The power of the hydraulic machine is also enough to turn on the irrigation.
Delivery of appliances from Kharkiv across Ukraine to any region.
