1. Company Profile

2. EEI – History and Principles
EEI’s mission started in 1978 coming from a consolidated experience in the sector of power
electronics, automation systems and manufacturing
technologies for different industrial processes.
We were able to combine the best electronic technology with our design skill.
Our deep knowledge of production processes could provide the best solutions to our
customers.
Over the past thirty years, EEI’s growth has been
gradual and continuous, reaching today’s over three
thousand systems running worldwide.
Today, EEI is the centre of a group of companies
working in synergy, each bringing its own capacity,
resulting from an exchange of knowledge and
continuous research, to the market.

18. Marine applications
EEI design and manufactures converter for
marine application, for both merchant ships,
military and yachting.
Product range includes:
‐ Inverters for on board application (thruster,
propeller, windlass)
‐ Shore power converter, for the connection of
ship load to the dockyard power supply
‐ SPS – Silent Propulsion System: the system
integrates power supply for ship load, battery
bank and thruster control for a efficient,
compact and silent functioning of the boat

19. Ropeways and Lift Transport System
EEI, because of its 30 years history in this sector, is the
ideal partner for ropeway systems for carrying
passengers and
materials. Thanks to the extremely high safety
standards reached during the long cooperation with
the world’s major manufacturers and the Government
Authorities,
Production includes following ropeway automation
systems:
• Reversible aerial ropeways
