De-tuning Reactors

Reactor Technology at its best.

Mangoldt Reactors LogoHans von Mangoldt standard line of Type DTR Capacitor De-Tuning reactors are specially made for power factor capacitor banks. Mangoldt offers exclusive PolyGap® core construction for minimum stray flux, minimum losses due to harmonics, and precise, balanced inductance in all three phases. Hans von Mangoldt has become the standard for excellence in reactor (inductor) design due to their precise inductance, accurate design and performance characteristics. Mangoldt Type DTR De-Tuning reactors protect capacitors from harmonics. UL listed 3 phase reactors.
