Intelligent systems for reducing costs and environmental impact
Harmonics Control
Harmonics Control in Power Systems
Harmonics are unwanted frequency components introduced into power systems by non-linear loads such as power electronics, arc furnaces, and adjustable speed drives. These harmonic currents and voltages can have detrimental effects including:
- Equipment overheating and failure
- Increased neutral conductor currents
- Communication and control interference
- Circuit breaker tripping
Filtering Solutions:
- Passive filters (cost-effective for specific frequencies)
- Active filters (dynamic wideband compensation)
- Hybrid systems (combines passive & active)
- Harmonic-mitigating transformers
Effective harmonics control through proper system design, mitigation strategies, and continuous monitoring ensures power quality and system reliability.
Refrigeration, Heating Ventilation & Air Conditioning
HVAC systems account for 38% of building energy consumption and contribute significantly to global CO2 emissions. Energy efficiency in HVAC is a critical intervention in the energy transition journey.
Coolnomix is a second-generation standalone, non-invasive intelligent thermostat with dual temperature sensors. It's a perfect control retrofit for vapor-compression air conditioners and refrigeration systems that modulate compressor runtime to save energy while maintaining temperature set points.

Power Factor Correction: Optimize Your Electrical System
What is Power Factor? Power factor is a measure of how efficiently an electrical system uses the available power. It's the ratio of real power (measured in kilowatts) to apparent power (measured in kilovolt-amperes). A power factor of 1.0 indicates that all the supplied power is used effectively, while a lower power factor means energy is being wasted.
Why is Power Factor Important? Low power factor can have significant impacts on your business:
- Higher utility bills – Utility companies often charge penalties for low power factor
- Wasted energy – Low power factor means inefficient energy usage
- Decreased system capacity – Reduces available power for your systems
- Potential equipment damage – Can cause motors and transformers to overheat
Power Factor Correction to the Rescue: PFC improves power factor to optimal levels (typically 0.95 or higher) through strategic placement of capacitor banks or power electronics devices in your electrical system.
Benefits of Power Factor Correction:
- Reduced utility costs – Avoid power factor penalties
- Increased system capacity – Free up power for your infrastructure
- Improved equipment lifespan – Reduce strain on motors and transformers
- Enhanced energy efficiency – Cut down on wasted electricity
Voltage Optimization Solutions
Voltage Optimization involves operating an electrical network at the lower level of the accepted voltage range. Due to distribution inefficiencies, utilities generally supply power to consumers at voltages higher than rated equipment voltages.
The problems associated with overvoltage include:
- Energy loss due to voltage-related (resistive losses) and joule losses in the distribution network
- Increased reactive demand, hence high Apparent demand (kVA)
- Reduction in equipment life and increased maintenance costs
- System breakdowns in extreme cases
IcoPower-Esco, with the help of its sister OEM Icopower, provides energy efficiency solutions through voltage optimization by utilizing ICO F Voltage Optimizers.
Key Benefits of ICO F:
- Verifiable electric energy and demand savings
- Harmonics control (reduction of THDi by up to 10%)
- Continuous data logging for accurate carbon reduction reporting
- Plant protection from overvoltage and increased equipment longevity
Variable Speed Drives
Variable speed drives are used to control motors in various applications. A VFD varies the speed of a motor by varying the frequency. The drive controls motor acceleration and deceleration during starting or stopping, respectively.
The synchronous speed of a motor is directly proportional to the AC power frequency. A VFD modulates the frequency to match the synchronous speed with the load requirement of the electric motor.
Applications:
- Heating, Ventilation & Air Conditioning (HVAC)
- Variable Air Volume Systems (VAV)
- Fan and Pump Control
- Water Pumping and Industrial centrifugal applications
Additional applications include Air Compressor Control and various process motor applications across industrial facilities.
