1991
Establishment of the company
ER3i launched its activity with IT development,immediately specialising in the Water and Energy business lines.
1999
Establishment of the Electrotechnical department
The team was complemented by experienced personnel proficient in the development and manufacture of electrical power and automation cabinets.
2005
Establishment of the Mechanical department
To be able to offer comprehensive “electromechanical” services, we recruited three hydroelectric mechanics specialists and established a branch in the Vosges.
2013
Construction of a new workshop
A new building was built for product manufacturing (turbines, screen rakes, grilles, valves).
2014
Commissioning of the first Kaplan turbine designed by ER3i
Following a lengthy R&D programme, we developed a Kaplan turbine for drops between three and seven metres which can operate at variable speed to maximise energy production and whose design reduces civil engineering costs as much as possible.
2014
Commissioning of the first hydrodynamic screw in partnership with LANDUSTRIE
To address the issue of sites with low drops (between one and three metres) and ecological continuity constraints, we signed a partnership with LANDUSTRIE (www.landustrie.nl) to be their distributor and integrator of hydroelectric screws for France.
2018
Joining the Gérard Perrier Industrie group
In order to develop ER3i, we joined the Gérard Perrier Industrie group as a shareholder. This partnership was possible because we could identify with the values of this group which has reinforced our financial and technical capability, but which also gives us access to logistical support across France through its various subsidiaries, all of which work on activities related to our business lines.
