LED retrofits, variable frequency drives, and modern HVAC controls are non-linear loads. They draw power in pulses, not smooth sine waves. That mismatch generates power quality problems that compound across your electrical system. Our device stops it permanently.
Many Industries. Same Result.
Informa Markets Saves 18%
"By reducing heat in our system, saving energy, and saving equipment, Tune is helping us champion sustainability in our business."
Caribe Resort Saves 14%
“Finding savings across three buildings seemed an impossible task. I didn’t expect much, but the results are undeniable.”
Popeyes Saves 9%
Three devices were installed at each location for a Popeyes franchisee across Georgia, Alabama, Louisiana, Mississippi, and Tennessee. Building sizes ranged from 2,200 - 2,700 sqft.
City of Rainsville Saves 10%
“We are not only saving money, we are already seeing savings in maintenance... I don’t get 5 calls a day about the issues at the new pumping station since we installed the filters.”
Introducing Tune
A Passive Harmonic Filter For Modern Buildings
Core Technology
What It Is: Two specialized air-core inductors wired in parallel on the panel’s neutral bus.
Filters Electrical Noise: Passes clean 60Hz power while trapping and dissipating destructive, high-frequency neutral line harmonics.
Built for Modern Loads: Mitigates “dirty power” generated by non-linear loads like computers, LED drivers, and VFDs.
100% Passive & Zero-Draw: Silent, zero-energy operation with no failure-prone circuit boards or software.
Impact on Your Facility
Reduces THD: Traps high-frequency neutral “trash” before it degrades sensitive facility electronics.
Lowers Operating Temperatures: Reduces thermal stress in wiring, panels, and transformers by filtering compounding harmonics.
Cuts Maintenance Costs: Extends HVAC motor life and prevents blown LED drivers, nuisance breaker trips, and PLC resets.
Proven Savings: Case studies show 10%+ utility cost reductions, driven by reduced transformer core losses, lower neutral conductor draw, and in eligible facilities, elimination of demand and power factor penalties.
Physics Not Promises
- Neutral harmonics cause transformer core losses (hysteresis, eddy current, and core resonance), that register directly on your utility meter. This is documented by the National Electrical Testing Association (NETA).
- A NETA study recorded a 6.5% kWh drop at the utility meter immediately after neutral filter installation, verified by utility-provided data. Savings are partly energy and mostly billing. We reduce bills, we don’t break physics. Our 10 – 20% is an average, not aggressive, and savings are primarily found from your bill. See Below.
