Harmonic Filter

Power quality is a significant concern for manufacturing and power generation facilities. This is due to harmonic disturbance and reactive power, which is produced by unbalanced loads, variable frequency drives and motors. These issues have serious consequences, including prematurely aging of equipment, unreliable controls, system synchronization loss, and increased energy, maintenance and replacement costs.

Enerdoor is an industry leader in radio frequency interference solutions. The Enerdoor harmonic filter series solves harmonic disturbance and power quality issues by compensating current harmonic and power factor correction generated by industrial loads.
