COMSYS Active Harmonic Filters in Dubai & UAE: Power Quality Solutions
DCPS Middle East supplies, installs and maintains COMSYS active harmonic filters for data centers, oil & gas, marine, manufacturing and commercial buildings across Dubai and the UAE.
Clean Power for Modern Electrical Networks
VFDs, UPS systems, rectifiers, LED lighting and EV chargers all draw non-linear current that fills your network with harmonics. The result is overheating transformers and cables, nuisance tripping, resonance problems, shorter equipment life and higher energy costs.
COMSYS, a Swedish power quality specialist, designs Active Dynamic Filters (ADF) that follow your load in real time and inject compensating current to cancel harmonic distortion. DCPS Middle East helps you measure, select, install and support the right COMSYS solution for your site in the UAE, from a single wall-mounted unit for a drive panel to a modular system for a whole plant.
COMSYS ADF: Active Dynamic Filters
COMSYS active filters connect to your main busbar or distribution board and respond dynamically to load changes, so they keep working even as your load profile changes.
Key features:
- Real-time harmonic cancellation across a wide range of harmonic orders
- Dynamic response to variable and fast-changing loads
- Reactive power compensation to improve power factor
- Resonance mitigation, which helps protect capacitor banks and equipment
- Wall-mounted and modular options in multiple current ratings
- Built-in HMI for easy monitoring and setup
- Suited to industrial, marine and commercial installations
COMSYS ADF Product Range
| COMSYS Range | Type | Typical Use |
|---|---|---|
| ADF P100 | Compact wall-mounted active filter | Drive panels, small to medium plants, commercial buildings |
| ADF P300 | Modular active filter | Industrial plants, data centers, marine and offshore |
| ADF P700 STATCOM | Active filter with dynamic compensation | Sites with harmonics, voltage dips and reactive power issues |

Active vs Passive Harmonic Filters: Which Do You Need?
| Active Filter (COMSYS ADF) | Passive Filter | |
|---|---|---|
| How it works | Measures the load and injects opposing current in real time | Fixed LC circuit tuned to specific frequencies |
| Load changes | Adapts automatically | Performance depends on the tuned design |
| Harmonic coverage | Wide range of harmonic orders | Targeted frequencies only |
| Extras | Can also compensate reactive power | Limited |
| Best for | Variable loads, VFDs, data centers, marine | Stable, predictable loads |
Many sites benefit from a combination. We help you choose based on measurements, not assumptions.
