Implementation of an energy management system at Etria Manufacturing
How Etria Manufacturing (formerly Toshiba) reduced its energy consumption by 50% in one year.
The Etria Dieppe site achieved significant energy savings after renewing its cooling units and air compressors. Additionally, with the MyDametis platform, the teams have become more autonomous in energy management.
“We called on Dametis in 2020 to carry out a project whose aim was to reuse energy from our processes to heat buildings. In the first year, we reduced our gas consumption by 50%. The MyDametis tool gave all our staff easy access to their consumption data, which they could then analyze.”

RESULTS
Results in figures
-50%
in gas consumption in the services building in 2022, due to the recovery of waste heat from air compressors and chillers.
– 40 000€
of energy savings on the annual bill in 2022 thanks to early detection of deviations. The result: better control of total heat energy
– 15%
in total heat energy consumption thanks to better optimization of heating control (scheduling, etc.) via MyDametis software and its energy management system.

CONTEXT
Etria Manufacturing, a leader in toner ink production.
A giant in the manufacturing of electronic and computer equipment, Etria also offers solutions in data storage, energy, and infrastructure.
Etria Dieppe (formerly Toshiba) is one of the two largest global toner ink production sites of the Japanese group. The site opened in 1986, and started out assembling photocopiers. In 1993, he began producing toner ink: spraying, plastic injection, bottling and cartridge assembly.

CHALLENGES
Overheating cooling units and worn-out air compressors
Overheating Chiller Units
The Toner building is dedicated to the manufacturing of toner cartridges. During the process, the machines generate a lot of heat. To prevent any risk of overheating, two chiller units condition the air and maintain the production circuit at the right temperature.
However, a problem arose: the chiller units started showing signs of fatigue, especially during heatwaves. This issue is critical for the Toshiba Dieppe site as the cold production must never be interrupted.
Worn-out and energy-consuming air compressors
At the same time, air compressors also began to underperform. As a result, their energy consumption was increasingly weighing on the energy bill.
Toshiba Dieppe needed to improve energy performance by renewing its air compressors in addition to its chillers.
Inadequate tools for energy management
As part of the signing of an Energy Performance Contract (EPC), Toshiba Dieppe had to achieve specific energy efficiency targets.
To monitor the site's energy consumption, the teams were using inadequate and impractical tools and modules. As a result, collecting, analyzing, and correlating each data point was time-consuming, tedious, and repetitive.
