Holcim engaged Danfoss for advanced VFD technology to assist in making its manufacturing site one of the most energy efficient cement plants in the world.
When a VACON® NXS drive was installed on a test fan in this Alaskan mine, the energy savings equated to 33 kW/h or annual savings of USD 100,000 for generator power.
VACON® AC drives improve the operation of underground ventilation and pumping systems and cut energy consumption of many application processes.
Back-channel cooling in VLT® AutomationDrives reduces substation heat load enabling use of a smaller air-conditioning system with lower power consumption.
Replacing the barge’s diesel engine with an electrical motor controlled by a VLT® AutomationDrive increased reliability and reduced costs.
90 kW VLT® Drives ease the mechanical stress on the heavy equipment and improve steering when the excavator turns sideways.
VLT® Drives move a 10.5-km-long conveyor belt. Load sharing between drives transfers energy from downhill segments to the uphill parts.
