Active Harmonic Filters
Eliminate Harmonics. Improve Efficiency.
Protect Your Equipment.
Modern electrical networks are full of nonlinear loads – from drives and inverters to heat pumps and renewable inverters – all of which generate harmonics that can reduce efficiency, cause overheating, and shorten equipment life.
Our Active Harmonic Filters (AHFs) provide a fast, reliable, and intelligent way to eliminate these problems and keep your systems running at peak performance.
Why Choose Active Harmonic Filters?
- Instant harmonic compensation for stable, clean power.
- Improved power factor and reduced reactive power demand.
- Protection for transformers, switchgear and sensitive equipment.
- Optimised network efficiency with lower losses and improved reliability.
- Compliance with ENA ER G5/5 harmonic limits.
Active harmonic filters offer superior flexibility and performance compared to passive alternatives, making it the preferred solution for todays dynamic electrical environments.
The Power Balance AHF – Compact, Efficient, Reliable.
Designed and manufactured in Germany, and stocked in the UK, our Power Balance range represents the latest in Active Harmonic Filtering technologies. Combining modular design, ease of installation with high reliability in a compact footprint.
Key features include:
- Modular ratings from 60A to 900A.
- Multiple formats (cabinet, wall mounted, floor standing) to suit any application.
- Real time harmonic compensation for multiple harmonic orders and phase imbalance.
- Intelligent control and monitoring for optimum system performance.
- Energy efficient operation (very low losses).
Applications Across All Sectors
Our AHF solutions are ideal for a wide range of industrial and installations, including:
- Water and Wastewater treatment plants
- Manufacturing and process industries.
- Renewable energy (Solar PV, Heat Pumps and battery storage).
- Commercial buildings with variable loads (HVAC, variable speed drives).
- Public infrastructure such as hospitals, universities, school and transport hubs.
Wherever power quality and reliability matters, our Power Balance filters deliver measurable results.
From Survey to Solution
We don't just supply equipment – we provide the expertise to ensure it performs flawlessly.
Our engineers can conduct a Power Quality Survey or a G5/5 Harmonic Assessment to define your exact requirements, recommend the right size of Filter and configuration, and support you through the installation and commissioning.
