Daikin Active Harmonic Filter

Daikin Active Harmonic Filter

An advanced, refrigerant-cooled and factory-integrated solution that actively cuts THDi to below 5% at full load, protecting sensitive sites and ensuring compliance — purpose-built for Daikin inverter-driven chillers.

Why Choose Daikin’s Active Harmonic Filter

THDi < 5% at full load
Active Front End (AFE) with IGBT control continuously monitors and reshapes input current for best-in-class harmonic mitigation.

Refrigerant-cooled stability
Cooling via the unit’s refrigerant circuit avoids the thermal drift and contamination risks common to air-cooled cabinets — ensuring reliable performance in harsh environments.

Unit-mounted and factory-integrated
No external floor space, cabling or third-party commissioning required. Faster installation, harmonised controls and fewer onsite risks.
