How Toshiba reduced its energy consumption by 50% in 1 year

The Toshiba Dieppe site has made huge energy savings after
renewing its chillers and air compressors. And thanks to the MyDametis platform,
teams are more autonomous when it comes to 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

Toshiba Dieppe, leader in
toner ink production

A giant in the manufacture of electronic and IT 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 worldwide. 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

Overheated chillers and
worn air compressors

1st challenge
1st Solution

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.

Installation of new
chillers

The priority was to replace the two chillers at the end of their cycle. Dametis installed two new ones to ensure and sustain cold production.

Chillers condition the air temperature by removing heat from the cooling area. Dametis recovers this heat to convert it into energy.

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.

Installation of new
compressors

Dametis has installed two new air compressors in the Toner building.

In order to optimize energy usage, Dametis has installed a heat exchanger that recovers the waste heat produced by the air compressors and chillers. This heat is then used as an energy source to heat the Services building dedicated to photocopier assembly.

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.

Energy Management
Faster and Easier

Dametis proposed to Toshiba to use its collaborative platform MyDametis. Thanks to this tool, teams can visualize real-time data related to compressed air consumption, chilled water, heating energy, and electricity consumption throughout the factory.

Centralized data, automated readings, comprehensive performance reports, intuitive interface: MyDametis simplifies teams' daily tasks, saves them valuable time, and makes them more independent in energy management.

Moreover, an alarm module triggers an alert as soon as a deviation is detected on the site. The tool notably identified an abnormal consumption level on a machine, which was then replaced.
