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 accessories
Every Gemi chimney fan installation requires accessories that connect the fan unit at roof level to the speed controller inside the building and allow the extraction rate to be adjusted for different operating conditions. Gemi Elettronica supplies a complete accessories range — variable speed controllers, heat-resistant cables, mounting brackets and spare parts — manufactured to the same specifications as the fan units themselves. Genuine Gemi spare parts are the only accessories guaranteed to be dimensionally compatible with current production Gemi fan units. Third-party components may appear similar but frequently differ in cable termination dimensions and controller voltage rating.
Variable speed controllers
The variable speed controller is the primary user interface for the chimney fan system, typically installed adjacent to the fireplace or stove at a convenient operating height. Gemi controllers provide up to six selectable fan speeds, allowing extraction rate to be reduced during a settled slow-burning fire and increased when lighting the fire, when the flue is cold or when external conditions create a temporary downdraught event requiring additional extraction.
Heat-resistant connection cables
The cable connecting the fan unit to the controller must withstand continuous exposure to flue gas temperatures at the point where it exits the fan housing. Gemi supplies cables rated for the maximum operating temperature of each fan model — 300°C for the basic galvanised fan, 700°C for the professional AISI 304, copper and Corten models. Cable is available in cut lengths to match any stack height from standard residential to tall commercial chimney stacks.
Replacement parts and maintenance items
Genuine Gemi spare parts — replacement fan blades, motor units, controller components and cable terminations — are available directly from the factory, ensuring that a chimney fan installed years ago can be returned to full operation without replacing the entire unit. This extends the effective service life of the fan significantly beyond that of products relying on third-party parts supply.

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.
With the current model we supply: grounding cable and cable with tweezers to be connected to the fence. With the dual power model, we provide a 220V power supply, cables for connections to the car battery (positive and negative), a grounding cable and a cable with tweezers to be connected to the fence.
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.
The signal lights that flash alternately on the energiser for electric fences indicate the correct operation of the appliance.
An energiser cannot be outdoors. It must be kept indoors to prevent it from being damaged by bad weather.
