Salonit Anhovo, the biggest cement production factory in Slovenia has the goal to reach the top 10 % most energy-efficient cement factories in the European Union. To support Salonit Anhovo with their energy management goals, Solvera Lynx is supporting them with LoRaWAN technology.
Salonit Anhovo is the biggest cement production factory in Slovenia. Founded some 90 years ago in the central valley of Soča, the factory has been an innovation driver for the region ever since. In the past ten years, the factory invested massively in its production line. Salonit also has a strong environmental regulation compliance strategy and it is dedicated to optimizing and reducing energy consumption. The goal was to reach the top 10 % most energy-efficient cement factories in the European Union.
Producing clinker is energy-intensive: its electricity consumption averages 85 GWh, with 2500 Tera Joules of energy used for clinker burning. In the past years, Salonit’s energy bills went up to 9 million EUR per year, mainly for electricity. The factory’s production is strictly linked to the market situation and energy consumption varies with the type of products they are manufacturing and how well they are doing with energy efficiency.
The inhospitable industrial environment with high moisture rate, extreme temperature conditions, and far-spread production areas, spanned over an area of more than 6 km2 made the project even more challenging.
Solvera Lynx offered a modern and innovative solution for smart energy management based on wireless LoRaWAN technology. It made deploying of challenging, previously cost-prohibitive energy management projects possible due to focusing on energy saving instead of investing in wired communication network.
Transmission of the data was done by our ComBox.L® communication equipment, which has long battery lifetime and suitability for the harsh industrial environment. In total we installed 36 ComBox certified devices, 11 of which are for gas metering, 10 are for water metering, 5 for compressed air, and 10 are used for electricity meters. The data was gathered and analyzed by advanced software platform GemaLogic®.
Salonit Anhovo team has created specific alarms on energy consumption and specific KPIs which link production data with energy consumption. Special analyses are also prepared such as M&T pairs for in-depth analysis of energy consumption. The EMS also automatically prepares energy usage reports, which are shared throughout the organization. Special reports are prepared and shared with Salonit’s top management.
