The Gemi electric fence - 100% Made in Italy - is used to ward off wild animals such as wild boars, deer, foxes, etc.
The purpose of electric fences is to protect the territory from unsightly invasions. It is also used to contain animals such as cows, sheep, pigs etc.
It has nothing to do with hunting. We have all the legal certificates available to produce and sell electric fences. This is the only legal solution for those who want to protect their plantations.

Chimney fan Corten
Gemi's Corten chimney fan delivers the same 3,800 m³/h extraction capacity and 700°C operating temperature as the professional stainless steel model, finished in weathering steel that develops a characteristic rust-brown patina forming a stable, self-sealing oxide layer. Manufactured in Italy, the Corten model is specified by architects and self-builders for contemporary and industrial-aesthetic projects where standard metallic finishes would appear out of place. The Corten model is stocked for immediate UK dispatch at factory pricing. All specifications, installation procedures and included accessories are identical to the professional AISI 304 model, with the single distinction of the outer casing material.
Weathering steel: appearance and performance
Corten — the trade name for a family of weathering steel alloys — forms a dense, adherent rust layer within two to three years of outdoor exposure. Unlike ordinary mild steel, this patina does not continue to corrode; it arrests further oxidation and protects the underlying metal without paint, lacquer or any periodic surface treatment. The deep amber-to-brown tones intensify over time, producing an appearance that architects increasingly specify alongside timber cladding and exposed concrete.
Suitable for contemporary and rural architecture
Where a copper fan suits a Georgian chimney stack and stainless steel suits a modern urban roofscape, Corten suits agricultural conversions, rural self-builds, artist studios and any setting where a warm oxidised finish reads as intentional rather than neglected. The fan dimensions and adjustable base ring are identical to the full professional range, so fitting is straightforward on any standard round or square flue terminal.
Professional specification, unchanged
Six-speed controller, heat-resistant cable and 3-year manufacturer's guarantee are included as standard. The fan unit installs without masonry work in under an hour and connects to the indoor controller via the supplied cable.

Questions and Answers
The electric fence for animals is neither dangerous for people nor for animals. As with everything, even for electric fences there is a standard that establishes the values to be respected.
The fence energiser is a product that emits intermittent pulses with a low amperage.
To create an electric fence for animals you need: a Gemi energiser - 100% Made in Italy - for fences that carries the current to the fence, an electrified conductor wire for the fence and insulators for electrified fences screwed on the posts to hold the wire.
Grounding is a fundamental thing for the functionality of the electric fence for animals, so it is recommended to do it correctly. To have the total discharge of current by the energiser, it is necessary to make the grounding by inserting 3 galvanized poles of 1 meter in the ground.
They must be positioned 3 meters apart, 80 cm in the wet ground and 20 cm outside, and then connect them with the yellow cable.
Together with the electric fence, we supply only 1 meter of cable that must be connected to the first pole. It is recommended to do it where there is the presence of vegetation, therefore a moist soil. Arid soil is not conductive. According to the tests carried out, placing 3 poles in any type of terrain, there will be no problem with functionality.
If you put only one stake, the power of the current felt will be less than its range and the animals will be able to cross the fence.
For a B12 energiser it is sufficient to use a 12V 40Ah car battery. The autonomy, if there is no dispersion in the electric fence, is about 10/12 days. Otherwise it lasts less.
If the current is far from the electric fence, for your Gemi energiser - 100% Made in Italy -, we have the high-voltage crossing cable that can work on the surface or underground, without discharging.
With this cable it is possible to carry current on the fence, without any dispersion.
The cable for electric fences can also be used to join two fences, then connect one end to a first fence and the other end to a second fence, when there is little distance between one fence and another.
To check if there is current on the electric fence for animals, just bring the tip of a screwdriver with an insulated handle a few mm away from the fence wire.
The moment you hear a ticking, it means that there is current on the electric fence.
An energizer cannot be kept outdoors. It must be kept indoors to prevent damage from the weather. In order to discharge all its current, it must be earthed by inserting 3 galvanized 1 meter stakes into the ground. They must be placed 3 m apart, 80 cm in the ground (wet) and 20 cm outside, and then connected with the yellow-green cable.
The device has a red positive cable at its output which is connected to the fence and a yellow-green cable which is connected to the first ground stake.
Never connect two electrifiers to the same wire, as the two impulses may cancel each other out, causing problems. You can connect two electrifiers to the same fence, but keep them on two separate lines of wire.
