Generator range

Efficiency and manageability reflect the spirit of this range which meets the very varied needs of the professional market, without ever neglecting the security aspects.

How to choose ?

Main use?

Nominal power ?


What types of devices to feed?

All devices do not consume power in the same way. Simple appliances such as incandescent lamps, heaters or hotplates have no special requirements. Equipment driven by an electric motor such as drills, circular saws or compressors require starting power. Single-phase (230 V) or three-phase (400 V)? Do you need three-phase power? Some tools require three-phase power. in this case you will appreciate the three-phase Tristar and Silenstar range.


Find the rated power of each device

This information is given by the manufacturer of your tool and is on the manufacturer's plate of your equipment. You can also find it in the user manual of your tool.


The power needed to start each device

Refer to the table of startup coefficients. Multiply this power rating by the starting coefficient of your device. Refer to the chart. The nominal power ratings of the tools in this table are given as an example and your device may have a different rated power (or normal power rating). For example, to power a professional 1400 W vacuum cleaner, you will need a minimum 28000 W (1400 x 2) generator set.


The starting power of all devices to power

After calculating the power needed to start each tool, add them together to obtain the total value of your power requirements. For the longevity of your group, increase this value by 20% and so you will have a power reserve.

Quality of power supplied?

Sound level ?


Single-phase or three-phase current?

Starting the engine?

Fuel gasoline or diesel?

Regulation of +/- 5%

Regulation of +/- 2%

Maximum protection of sensitive tools

83 - 92 dB (A)

95 - 97 dB (A)

If the place of use of your generator is in a place where the noise is controlled, the range of Inverters and Soundproof gensets is there to bring you maximum working comfort. (See the noise scale by clicking here.)

Up to 3 H

Between 3 H 30 and 7 H 30

More from 8 H

230 V Voltage


230 V and 400 V

Manual start

Electric start

Frequent use

Daily use

For everyday use and over a long period the choice of a diesel engine is the best.

The simplest power tools do not require any particular power quality. On the other hand, electronically controlled electrical equipment requires a precise maintenance of the voltage as well as the frequency of the current supplied. We offer three types of regulation covering all your needs:
Condenser or compound

All our generators are equipped with capacitor (single-phase) or compound (three-phase) voltage regulation +/- 5%

AVR (voltage regulator)

Electronic device regulating the voltage (Volt) of the alternator +/- 2%. It is advisable to opt for this device for equipment sensitive to voltage variations.


Guarantees the best technology to protect all types of tools, perfect power, quiet operation and low power consumption.
