Applications by Machine Type
Today's advanced production processes often have complex electrical behaviors that are impossible to manage with conventional passive technology; it is simply too slow and inaccurate. The active energy conditioner ADF is designed to master even the most intricate and rapid behaviors. This section exemplifies a fraction of applications and processes where ADF comes in useful.
Variable Speed Drives
The energy conservation ability of variable speed drives (VSD) has rendered them a lot of popularity. They also play important roles in many automated processes. However, the VSDs corrupt the mains supply and inflict disturbances and losses to equipment connected to the network.
Presses
The electrical behavior during a press cycle changes rapidly and the consumption of reactive power is extremely dynamic. It is thus impossible to compensate with conventional passive techniques. Moreover, the load profile depends on several things that are subject to change as production processes are realigned, including the thickness of the material to be pressed, the shape, the materials characteristics and more.
Frequency Converters
Frequency converters have many advantages when it comes to motor control and process automation. However, their electrical behavior is often polluted with severe harmonics causing disturbances, energy losses and premature equipment aging.
Furnaces
Furnaces and casting crucibles are some of the most energy intensive industrial production processes. Electric arc furnaces (EAF) are known to give rise to flicker and other disturbance behaviors that might develop into large costs for both society and companies. ADF reduces the energy consumption, shortens the melting time and eliminates disturbances.
Start/Stop of Large Equipment
As starts and stops of large equipment take place, voltage variations and transients can stall or interfere with other connected equipment. Mitigating these phenomena can turn into productivity improvements and production flexibility as starts and stops can be made at any moment.
Extruders
The extrusion process is sensitive to disturbances and is dependent on precise steering to avoid production problems. ADF is the ultimate tool to prevent costly stops due to poor power quality.
Pumps
The performance of pumps is critical in many industries, including gas and oil, pulping, and water treatment. Varying flow and density spur to usage of variable speed pumps which generate harmonics and other undesired costly electrical behaviors.
Hauling
Mine hoists and other hauling processes put the electrical network under considerable stress during the acceleration and brake phases. ADF manages the need for reactive power at every instant and provides for ideal power conditions.
Welding Systems
Electrical welding systems demand extremely high current during short periods. This usually results in high and dynamic reactive power consumption and extensive harmonics leading to severe voltage fluctuations that cause production disturbances and flicker. ADF eliminates the reactive behavior and stabilizes the power grid.
Lamination
The lamination processes is energy consuming and dependent on accuracy. With ADF comes significant energy savings hand in hand with enhanced production efficiency.
Packaging Machines
The function mode of packaging machines enables considerable energy savings. ADF has proved to be able to reduce the energy consumption by over 10% in packaging applications.
Mills
The grinding process confronts companies with low power factor and harmonic distortion. ADF gets reactive power and harmonics under control.
Fluorescent Tubes
Although fluorescent lamps are more energy efficient than traditional light bulbs, there is more money to be saved. In facilities and warehouses where fluorescent tubes stand for the lighting, the amount of zero sequence harmonics (3rd, 9th ...) relatively soon grows to levels where it becomes profitable to filter.
UPS Systems
UPS systems connected to networks polluted with harmonics run the risk of malfunction and shortened lifetime. The costs of failing power supply might grow beyond predictability. ADF helps you to secure uninterrupted power supply and production uptime.
Hydraulic Cranes
Hydraulic cranes used in harbors and warehouses display rapid and dynamic reactive behavior. ADF is the guarantor for lower energy costs and eliminates charges for reactive power.
