Multinational manufacturing company, Danfoss, has launched its new Advanced Active Filter AAF007, for use in energy-saving harmonic mitigation of HVAC units.
Harmonic distortion in HVAC systems can lead to increased energy consumption and heat losses in motors, transformers, and wiring while causing a malfunction in variable frequency drives and control systems.
The Danfoss Advanced Active Filter AAF007 can mitigate this harmonic distortion, bringing several benefits to plant rooms – including improved energy efficiency, enhanced system lifespan, better power quality, and compliance with regulatory requirements and industry standards.
The company claims the product achieves 98.2 per cent filter efficiency using advanced SiC technology. The newest-generation SiC switches allow for unmatched efficiency, with 60 per cent lower power losses compared to similar filters.
The Danfoss Advanced Active Filter AAF 007 is designed to reduce harmonic distortion of central or decentrally installed Danfoss drives, and is compatible with all drives in the Danfoss product portfolio.
Highlighted features include:
- Compact modular design reduces space requirement
- Easy serviceability reduces service time and cost
- Automatic detection of resonance to adjust switching frequency improves uptime
- Low complexity, with one product managing multiple power quality challenges: harmonic mitigation, power factor correction, and imbalance compensation
- Highly efficient and robust, for long life with low total cost of ownership
- Fast commissioning with plug and play capability and easy parameterization via Danfoss AAF 007 Setup Tool PC software and/or RS485
- Easy to retrofit to existing installations, when harmonic distortion increases with addition of non-linear loads
- Available as fully integrated or modular solution for self-integration
- Large local touch panel, with cabinet-integrated solution available for easy access
Danfoss’ APAC office is based in Dandenong, South Australia. For more information on the AAF007 and other solutions, the full product range is available online at danfoss.com.
