– Jermaine Reyes, Marketing Associate at MIRUS International, says:

The first passive harmonic filter that outperforms an active filter

MIRUS International has launched a new, high performance passive harmonic filter that matches the performance of Active Front Ends (AFE) or Active Harmonic Filters (AHF). Known as the LINEATOR High Performance (HP), it reduces harmonic currents drawn by standard 6-Pulse Variable Frequency Drives (VFD) to <5% ITHD at full load and <5% ITDD over the entire operating range. This level of performance is equivalent to or better than more complex AFE Drives, especially when frequencies above the 50th harmonic are taken into consideration. Applications in data centers include CRAC units, chillers, chilled water pumps, cooling tower fans and other VFD motors.

Avoids high frequency voltage distortion and EMI interference

Unlike AFEs or AHFs, the LINEATOR HP ‎passive harmonic filter does not inject higher frequency voltage distortion (frequencies above the 50th up to the 100th harmonic) or higher electromagnetic interference (EMI) common-mode voltages and ground currents into the electrical supply systems of data centers. These higher voltage harmonics are known contributors to failures in data center equipment, including servers, communications equipment, critical electronic controls, circuit breakers with electronic trips and other crucial power system protection equipment.

Increased reliability and increased savings

Specifying the LINEATOR HP for application with standard 6-Pulse VFD’s provides data centers with low harmonic drive systems at 20 to 30 per cent less in capital costs than other solutions. And with >99% efficiency, the LINEATOR HP offers at least 2 percent efficiency gains over active solutions thereby, significantly lowering operating costs.
