ONICS Energy

Total Harmonics Distortion (THD) causes problems in your power distribution system. THD also affects non-linear load equipment such as computers and printers, new generation lighting, industrial machinery, uninterruptable power supplies, HVAC units, and solar panels to name a few. These problems can lead to over-heating and failure of equipment, power losses of select power system distribution components, energy waste. That energy waste equates to thousands of dollars of unnecessary costs each month.
Onics Energy’s patented and certified Harmonics Filters deliver real energy savings by mitigating energy waste due to THD. Almost any type of business can save up to 25% on their electricity bills with this cutting-edge technology.

Benefits of Installing Harmonics Filters

  • Increased Power Efficiency
  • Extended Equipment Lifetime
  • Reduced Voltage Glitches
  • Reduced kWh Consumption
  • Cut in Equipment Maintenance Costs
  • Savings on Electricity Expenses
  • Positive ROI within Months
