Applications by Industry

This section exemplifies applications in various industries where the ADF Active Filter can be used to improve operational and environmental performance. Click on your industry to learn more.


Water Treatment

Pumps and feeding screws are used in the water treatment industry to dynamically control liquid levels, flows and consistencies. ADF Active Filter is the tool to save energy and take the sting out of harmonics and other disturbance behaviours.

Offshore Oil and Gas Industry

Offshore oil and gas platforms sometimes suffer from weak or instable electrical networks. This is a consequence of own local power generation. By letting ADF Active Filter monitor and manage the network, production uptime is ensured through disturbance free and reliable power supply.


The economics of continuous processes like refinery are based on high availability, high volumes and cost awareness. Reduced energy costs and mitigated production disturbances are some of the benefits of ADF Active Filter. Compressors and pumps are two typical applications within refinery.

Steel and Aluminium Industry

Manufacturing of steel and aluminium is highly energy intensive why every percent reduced energy consumption quickly can send large savings directly to the bottom line. Moreover, processes like induction melting might cause electrical interference with other equipment.

Harbour Cranes

Loading and unloading ships involves large cranes with considerable energy costs. Especially hydraulic cranes display a dynamic demand for reactive power that active filtering technology like ADF Active Filter is outstanding to satisfy.

Automotive Industry

Being one of today's most competitive industries, automotive manufacturers constantly seek ways to streamline production and reduce costs. This often includes automation and installation of advanced machinery. Equipment like electric welding systems, robots and presses share rapid and complex electrical behaviour. Traditional passive technologies to suppress reactive power are unable to follow their dynamic behaviour leading to higher energy consumption. ADF Active Filter ensures complete power factor control and lower energy costs.


The foundry business is very energy intensive. The consumption behaviour is dynamic, i.e. it varies over time, which stresses the importance of active filtering technology to optimize the energy conditions.

Metal Processing

Milling, welding, and grinding are examples of metalworking processes where electricity is used dynamically and randomly. ADF Active Filter surge for the right amount of reactive power at every instant. It is even capable of managing the high and rapid currents stemming from electrical welding systems.

Manufacturing Industry

Manufacturing in today's competitive business environment means adding more value to products and machineries. This leads to more sophisticated constructions and complex assembly. The cost of failure increases and accentuates the importance of disturbance free production. ADF Active Filter is your assurance for optimal energy conditions and minimized consumption.

Pulp and Paper Industry

The start and stop of large machinery, like wood chippers and the paper machine itself, can cause voltage variations and transients to spread throughout the network. The paper finishing process with its large cranes and slitter cuts is another area of interest. Not to forget is the handling of the process water and water treatment facility where variable-speed drives and pumps consume reactive power and generate harmonics.

Plastic Fabrication

Injection moulding and 3D-layering are examples of plastic fabrication processes where automation and variable-speed drives are essential to maintain constant quality and avoid disturbances. ADF Active Filter resolves that and ensures safe and optimal energy conditions for sensitive manufacturing processes.


The packaging industry features large machines whose energy consumption becomes more complex as automation increases. Also, the fabrication of the packaging material itself often involves lamination and extrusion, two well-known applications where ADF Active Filter has proven its performance.

Process Industry

An increasing amount of equipment with non-linear electrical behaviour is connected to the network as process plants are becoming automated. These machineries, including variable-speed drives and computerized machines, pollute the network with disturbances and losses that add up to considerably higher energy costs. Large energy consuming machines constitute other applications with large savings potential.

Food Processing

Food processing can be comprised of liquid processing, grinding, milling, pressing and many more processes. They all share similar dynamic reactive behaviour that is ideal to manage with ADF Active Filter.

Utility Companies

The European electricity system is under strain due to overall growth. This can be solved by either investing in more capacity or reducing consumption by users. Saving rather than investing in new capacity is an extremely cost effective way for society and beneficial for the environment. Comsys provides the unique ADF Active Harmonic Filter solution, which reduces consumption as well as peak demand and at the same time improves end user productivity.

Furthermore, an increasing number of connected equipment with non-linear electrical behaviour is connected to the network. These cause losses and reduce network productivity. By removing the loss creating behaviours, ADF Active Filter gives room for supplying more customers and improve network capacity for utilities.
