    Bertoli generating sets are intended for the supply of electric power in case of public mains failure, or where there is no mains available.

    Our range of generating sets spans from 3 to 2000kVA generating sets

    All our production, from inception to completion, is carried out in Italy. All the components used in our manufacturing process are made in western countries.

    For our generating sets, we design and produce weather and soundproof enclosures and trailers for towing on roads or off road (high speed) or on fields (low speed).

    Bertoli has profound knowledge and skills in the design and construction of special applications, too. Over the years, we have provided numerous companies and institutions throughout the world with our solutions.

    The experience gained is a precious heritage at our partners’ service; however, every situation requires the expertise of Bertoli’s technical and sales staff, based on an accurate planning and construction procedure.

  • Mobile Floodlight Units

    Bertoli floodlight units are supplied with mobile generating set from 6 to 30 kVA equipped with 5-9 m high telescopic mast with halogen lamps as standard. HPS, metal halide or Led lamps are available on request.

    Generating sets can be easily removed from the trailer with the floodlight unit and used independently

    Depending on power and models, telescopic masts can be raised and lowered manually by means of a winch with automatic brake or they can be supplied with pneumatic or hydraulic raising/lowering system.

    Floodlight units are equipped as standard with single axle trailer designed for low speed towing.

    Flood light units can be equipped, on request, with a high speed trailer for towing on roads.

    Fast trailer is different from low speed trailer for the fact that can be equipped with special features that make it capable of being homologated to be moved on public road (homologation is at customer’s charge).
