How Toshiba has
reduce consumption
34% energy in 1 year
renewed its chillers and air compressors. And thanks to the platform
MyDametis, teams are more autonomous in energy management.
RESULTS
The results in figures
energy consumption on the Toner process in 1 year, for a reduced environmental impact. Consumption fell from 1512 MWh to 998 MWh.
CONTEXT
Toshiba Dieppe, leader of the
toner ink production
A giant in the manufacture of electronic and computer equipment, Toshiba also offers solutions in data storage, energy and infrastructure.
Toshiba Dieppe is one of the Japanese group's two largest toner ink production sites in the world. The site opened in 1986 and started its activity with the assembly of photocopiers. It was in 1993 that he began to produce toner ink: spraying, plastic injection, bottling and assembly of cartridges.

Toner manufacturing building. Includes 2 chillers for machine cooling and 7 air compressors.
Building dedicated to the logistics of finished products.
ISSUES
Overheated chillers
and worn air compressors
Overheated chillers
The Toner building is dedicated to the manufacture of toner cartridges. During the process, the machines generate a lot of heat. To avoid any risk of overheating, two cold units condition the air and keep the production circuit at the right temperature.
But there was a problem: the cold groups began to show signs of fatigue, especially during periods of heat. This issue is critical for the Toshiba Dieppe site because cold production must never be interrupted.
Installation of new
cold groups
The priority was to replace the two cold units at the end of the cycle. Dametis has installed two new ones in order to ensure and sustain cold production.
Chillers condition air temperature by removing heat from the area to be cooled. This heat, Dametis has recovered to transform it into energy.
Worn air compressors and
energy guzzlers
At the same time, air compressors also began to underperform. Consequence: their consumption weighed more and more on the energy bill.
Toshiba Dieppe needed to improve energy performance by renewing its air compressors in addition to its refrigeration units.
Installation of new
compressors
Dametis has installed two new air compressors in the Toner building.
In order to optimize energy, Dametis has installed a heat exchanger that recovers the waste heat produced by air compressors and refrigeration units. These calories become a source of energy that heats the Services building dedicated to the assembly of photocopiers.
Tools unsuitable for
energy management
As part of the signing of an energy performance contract (EPC), Toshiba Dieppe had to achieve specific energy efficiency objectives.
To monitor the site's energy consumption, the teams used inappropriate and impractical tools and modules. Consequence: collecting, analyzing and correlating each piece of data was long, tedious and repetitive.
energy management
faster and easier
Dametis proposed to Toshiba to use its collaborative platform MyDametis. Thanks to this tool, the teams visualize in real time data related to the consumption of compressed air, chilled water, heating energy and electricity throughout the plant.
Centralized data, automated readings, complete performance reports, intuitive interface: MyDametis simplifies the daily lives of teams, saves them precious time and makes them more autonomous in energy management.
Finally, an alarm module launches an alert as soon as a drift is detected on the site. The tool notably identified an abnormal level of consumption on a machine, which was replaced.
