How the Daikin Active Harmonic Filter Is Redefining Innovation in HVAC
With rising expectations for energy efficiency, tightening environmental regulations, and an increasing demand for reliability and uptime, engineers and facility managers must look beyond conventional solutions.
At Daikin Applied (UK)Daikin Applied (UK), innovation is more than product development; it is a cultural commitment to engineering better outcomes for our customers, our planet, and future generations.
A Breakthrough in Power Quality
Among Daikin’s latest R&D achievements is the Daikin Active Harmonic Filter (AHF), a fully integrated, advanced solution explicitly designed for inverter-driven chillers. It addresses one of the most persistent challenges in HVAC power systems: harmonic distortion.
Traditional Variable Frequency Drive (VFD) chillers can experience Total Harmonic Distortion of Current (THDi) levels exceeding 35%, which can lead to:
- Overheating of cables and transformers
- Nuisance tripping
- Failures in sensitive electronic equipment
- Non-compliance with utility power quality standards
Embedded Innovation: A Fully Integrated Design
While traditional power filters are freestanding and require additional space, cabling, and coordination with third-party suppliers, the Daikin AHF is mounted within the chiller’s electrical cabinet.
This integrated approach provides:
- Faster and simpler commissioning
- Reduced installation complexity
- Enhanced system harmonisation
- No additional cooling or maintenance requirements
Adding further intelligence is Daikin on Site (DoS) a remote monitoring and control platform that provides:
- Live operational data
- Intelligent alerts
- Predictive maintenance insights
- Remote system adjustments
Designed, Manufactured, and Owned by Daikin
What truly differentiates the AHF is that it is designed, manufactured, and fully owned by Daikin.
This provides:
- Total compatibility with Daikin VFDs and chillers
- A single-source, fully supported solution
- Comprehensive warranty and lifecycle services
Performance-Proven in Mission-Critical Environments
The Active Harmonic Filter is already proving its value in high-demand, mission-critical environments, including the Green Mountain hyperscale data-centre campus in Norway.
As part of a wider Daikin solution delivering a combined cooling capacity of up to 115 MW, the integrated AHF helps ensure stable, efficient, and reliable operation, demonstrating the scalability and performance of Daikin’s power-quality technology at a hyperscale level.
Conclusion: Innovation Built In, Not Bolted On
At Daikin Applied (UK), innovation is embedded by design. The Active Harmonic Filter exemplifies how we’re redefining expectations for HVAC efficiency, reliability, and sustainability.
Whether your facility is a data centre, hospital, industrial plant, or commercial building, Daikin technologies are engineered not only to perform but to adapt, evolve, and safeguard your investment for years to come.
