Comsys

What Comsys does

Comsys AB is a Swedish cleantech company founded in Lund in 2001 by Dan Liljengren and Jonas Persson, specializing in power quality management and battery energy storage solutions based on its proprietary Active Dynamic Filtering (ADF) technology. The core ADF platform uses IGBT-based power switching combined with real-time digital signal processing to eliminate harmonics, correct power factor, compensate flicker, eliminate resonance, and balance loads in electrical systems. Its product portfolio spans the ADF P100 G4 and ADF P300 families for commercial and industrial applications, the high-capacity ADF P700 STATCOM for grid-connected use, the PPM300 power quality module for parallel operation, the SCC2 control and monitoring software, and Dynamic Energy Storage (DES) systems built around second-life EV batteries.

Comsys generates revenue through a mix of hardware sales (one-time equipment purchases), subscription-based software and service contracts, and project-driven professional services including feasibility studies, installation, and commissioning; pricing is custom and quote-based, typically delivered under multi-year contracts. The company sells to enterprise customers across marine, industrial, data center, renewable energy, and water treatment verticals, with named accounts including Samsung, Microsoft, Volvo Cars, Siemens, Fortum, Vakifbank, Nordlaks, and Crisp Malt, and pursues both direct enterprise field sales and a channel of 150+ partners across five continents supported by ADF Academy training programs.

The firm holds an unusual stack of industry certifications for its size, including the first DNV GL type-approved full range of active harmonic filters for maritime use, Lloyd's Register type approval, UL listing, ISO 9001 and 14001, and Seismic OSP-0718 (GR63 Core Zone 4) approval. It operates a wholly-owned US subsidiary, Comsys Inc., with a manufacturing facility in Atlanta, Georgia established in 2021 to serve North American customers, and the company is currently privately held with leadership including CEO Rickard Jacobson, Head of Research and Innovation Dan Liljengren, CTO Jonas Persson, and Head of Product and Operations Development Dennis Magnusson.
