METRON proposes a 4.0 solution to reduce Energy consumption based on Big Data, AI and ontologies (knowledge data base of industrial and Energy). METRON connects to any type of equipment (to identify all influencing parameters, setting baselines detecting drifts in real-time) and based on a strong and secured architecture detects in real time, non-intuitive optimizations on process and utilities (Air compressors, boilers, Steam, chemical Reactors ..), reaching 4% to 15% energy consumption savings on more than 100 clients
