Actemium Maintenance & Energies Auvergne

As experts in industrial processes, Actemium Maintenance & Energies Auvergne is present across the entire value chain. It is involved at every stage, from diagnosis to the implementation of low-carbon solutions, from engineering to consulting, from electricity to mechanics. Actemium is committed to offering turnkey solutions tailored to the challenges and needs of its customers.

Actemium’s raison d’être: Industrial efficiency.

Actemium’s ambition: To ensure the long-term viability of its industrial customers’ tools, while combining energy savings and 4.0 maintenance to make them more competitive.

CHALLENGE: Reduce energy consumption by better managing industrial uses

Actemium Maintenance & Energies Auvergne’s aim is to identify significant energy use in its customers’ industries, enabling them to make energy savings. To achieve this, Actemium Maintenance & Energies Auvergne implements energy monitoring for all types of energy. This approach makes it possible to detail and analyze the consumption of targeted equipment.

The solution must enable:

determine an appropriate metering plan,
set up new metering equipment or adapt the existing metering system, in order to establish communication between the metering equipment and an online energy supervision platform.

SOLUTION: IoT, a key lever for optimising energy performance in industry.

Why choose the IoT?

Actemium turns to IoT for efficient energy management.

The IoT makes it easy to establish communication between measuring devices and energy supervision.

Using devices that communicate wirelessly makes installation easier and less costly.

In addition, battery-powered IoT equipment is essential for connecting isolated metering devices, such as water meters located in manholes where there is no electricity.

Finally, IoT continuously captures high-frequency data, enabling detailed analysis of consumption.

Which IoT sensors for energy monitoring?

Pulse counting

The products most commonly used by Actemium Maintenance & Energies Auvergne are the PULSE and PULSE ATEX sensors, which can be easily adapted to all types of measuring equipment by counting the number of pulses generated.

Many measuring devices generate a pulse when their consumption index is incremented, enabling remote reading of electricity, water, gas, compressed air, steam and also production data.

PULSE transmitters are generally connected to electricity meters (Schneider, Socomec or others) or water meters. ATEX PULSE sensors are used to connect gas meters, to comply with current regulations. For each kWh, m3 or Nm3 measured, a pulse is generated and counted by the transmitter. The transmitter’s pulse index is then transmitted to a centralised system, which communicates the data to the energy supervision system.

Modbus protocol

Actemium Maintenance & Energies Auvergne also uses MODBUS transmitters because they communicate directly with the exchange table of measurement equipment or PLCs. They allow more data to be processed at an even higher frequency than PULSE transmitters.

MODBUS transmitters are used when the existing measurement system does not offer a pulse output. The Modbus communication protocol is widely used on many electrical devices (meters, protection devices, etc.) and flowmeters.

The MODBUS transmitter is used to interrogate the equipment’s exchange table and return the required data. Then, in the same way as for PULSE sensors, the data is transmitted to the energy supervision system.

Temperature sensors

TEMP and TEMP2S temperature sensors are used to measure ambient temperatures in the workshops or outside the factory. These temperature data are then correlated with heating consumption data.

RESULT: data to reduce consumption in your industry

Adeunis devices are easy to use, both to set parameters and to install. They are suitable for DIN rail or pipe installation.

Adeunis equipment enables Actemium Maintenance & Energies Auvergne to collect all the necessary data from its industrial customers, creating a comprehensive and sustainable consumption database.

By analysing this data, it is possible to identify deviations or optimisations in energy-consuming equipment.

What savings can you expect?

The energy savings generated by energy monitoring depend very much on the customer’s initial situation. For example, a plant with little experience of energy efficiency will see significant and rapid gains.

Often the first task is to analyse and reduce the energy footprint (constant minimum consumption).

In general, intelligent monitoring of consumption generates a reduction of 2 to 5%. The ROI depends on the complexity of the metering plan installed. On average, Actemium Maintenance & Energies Auvergne observes ROIs of around 5 years.

Once again, these indicators depend on the situation at each plant.
