Energy Filter
TECNA designs and manufactures power quality filters that protect industrial equipment, reduce unplanned downtime, and maximize production output worldwide.
The animation above shows how a TECNA filter works: a distorted electrical signal (left) — carrying harmonics, transients, and noise — enters the filter and exits as clean, stable power (right).
Power quality, engineered for industry.
High-frequency noise, transients, and voltage fluctuations silently degrade equipment, disrupt production, and increase energy bills. TECNA designs and manufactures filters that stop them, purpose-engineered for the real-world demands of industrial facilities worldwide.
Waveform filter
High-frequency noise filter, super-harmonic and harmonic filter for protecting VFD, electronics and PLC.
Transient protection
Suppressors rated for the worst industrial surges — from capacitor switching to lightning.
Power continuity
Supercapacitor UPS systems for zero-transfer-time backup in critical processes.
Built for demanding environments
From food processing lines to steel mills, TECNA filters work where power quality matters most.
Industry
Robots, production machines, and automated assembly lines.
Commerce
LED lighting protection, air conditioning, and commercial equipment.
Laboratories
Metal detectors, X-ray, scales, injection machines, and Videojet printers.
Proven in the field
Real installations. Measurable results.
Latam food processor reduces unplanned downtime by 43%
Installing TECNA HF filter across 12 VFD panels eliminated interference tripping safety relays — reducing monthly maintenance hours by half.
Steel mill extends transformer life by an estimated 8 years
Active harmonic and unbalance filter upstream of a furnace brought THD from 38% to under 5% within IEEE 519 limits, achieving 4% direct energy savings.
Laboratory achieves stable power for sensitive equipment
HF Filter and supercapacitor installed before X-ray and metal detection equipment eliminated false readings caused by conducted interference from nearby machines.
