Final testing phase for the customer-friendly Enersolve Project

At this crucial stage, the Enersolve project has reached its final testing. This customized solution was developed for the specific needs of a major glassworks located in northern Italy. The glassworks, a leader in its field, is an example of its commitment to environmental sustainability and the adoption of new technologies.

Environmental Sustainability and Circular Economy: a priority for the Client

75% of the Customer’s production derives from the use of recycled glass. To achieve this important result, also from the circular economy and environmental sustainability point of view, it uses a large furnace that works by means of electrodes that cause the fusion of glass through the formation of an electric arc. In addition to being an energy-intensive technology (overall process consumption approx. 7gWh/year), service continuity is very critical and requires a quality power supply that meets well-defined parameters.

Enersolve solution for energy efficiency

Given the importance of maintaining high levels of production and ensuring energy efficiency, the Client opted for an Enersolve solution. This choice not only provides an estimated 3% to 4% energy savings, but also brings the plant up to the parameters required for proper operation.

Enersolve ESL-10: new technology for energy savings

The selected solution is the 3200-kVA Enersolve ESL-10, with a number of optional extras that further enhance its functionality. This system includes input switches, an override bypass, and direct selection of the output target voltage. The size of the equipment is impressive, with a structure of 7000x1000x2300 mm and a weight of nearly 60 quintals.

ENERSOLVE range in 3 models

  • ESL-5 for the retail/small business market.
  • ESL-10 for environments where energy parameters fluctuate within the requirements of the ±10% reference standard.
  • ESL-20 for the most severe cases where fluctuations exceed the requirements of the reference standard.

Energy saving and parameter measurement Industry 4.0

The added value of the ENERSOLVE solutions is undoubtedly represented by the ENERCLOUD platform, which is essential for displaying and analysing energy parameters and a prerequisite for obtaining the benefits linked to Industry 4.0 plans. The on-board instruments make it possible to read and record the values of all the plant’s electrical parameters, hence processing energy-saving data in real time. The method used to process the energy-saving data is based on the principles of the ESPRO protocol approved by ENEA (National Agency for New Technologies, Energy and Economic Development) after 3 years of joint studies.

The ESPRO protocol enables dynamic savings measurement: it is not based on measurements before and after the implementation of the energy efficiency implementation but rather enables continuous savings measurement.
