By addressing more than just simple harmonics tuning, Comsys ADF technology actively mitigates a wide range of natural and unpredictable power quality issues that arise from complex onboard grids.
Comsys is helping the maritime industry accelerate decarbonization by improving onboard power efficiency. Our Active Dynamic Filters (ADF), built for low and medium-voltage marine grids, reduce power defects and ensure more of your generated electricity is put to productive use.
By mitigating a wider range of power quality issues and being easy to size, install, and maintain, retrofittable Comsys ADF can increase usable grid capacity by 10% or more on vessels of any size.
This supports better fuel performance, extends component lifetime, and ensures the stable, compliant operation required for seaworthiness.
Starting January 1, 2023, all ships must calculate their EEXI and begin annual monitoring for the Carbon Intensity Indicator (CII). These requirements place an operational focus on energy efficiency and power system behavior.
Comsys ADF helps vessels meet and exceed these standards by optimizing power quality, reducing energy waste, and stabilizing performance under varying conditions.
Comsys ADF is uniquely adapted to the challenges of onboard electrical systems. It supports modern vessel topologies and delivers the stability required for efficient, compliant operations.
