The Problem

When Refrigeration Harmonics Meet Process Precision

Food and beverage manufacturing combines heavy refrigeration loads that create massive harmonic distortion with precision process control that needs clean, stable power. These two requirements fight each other on the same network — and your energy bill, product quality, and equipment life all suffer.

What Causes It

Compressor Harmonics and Batch Demand Spikes

4–8 large compressors on VFDs, each generating 30–60% current THD, push system voltage THD to 6–8%. CIP cycles add 300–800 kW demand spikes. The interaction between compressor harmonics and sensitive servo drives on filling lines creates subtle accuracy issues affecting product consistency.

How power quality affects product consistency + Read more− Close

Filling line servo drives require stable voltage for accurate positioning. Voltage distortion above 5% THDv causes micro-positioning errors affecting fill volume accuracy. Weighing system load cells are similarly affected — harmonic noise causes measurement instability that forces wider tolerance bands. The cost isn’t dramatic failure; it’s increased giveaway, more rejections, and higher waste.

The Solution

How HarmoniQ Works

HarmoniQ’s narrowband tuning technology eliminates the conflict between heavy refrigeration loads and precision process control. Sampling 20,000 times per second, the system maintains clean 50/60 Hz power across your facility.

HarmoniQ Filter

Eliminates compressor and process VFD harmonics, reducing THD below 5%. Extends refrigeration motor life by 20–35%.

HarmoniQ Filter
HarmoniQ Alpha

Stabilises voltage for process control accuracy — protecting filling lines, weighing systems, and packaging equipment from consistency drift.

HarmoniQ Alpha
HarmoniQ Booster

Corrects power factor from 0.72–0.86 to 0.98+, reducing demand peaks from CIP and batch start-ups.

Beyond the Bill

Product Quality, Equipment Life & Retailer Requirements

Cleaner power means more precise filling, less giveaway, fewer quality rejections, and compressor motors that last 20–35% longer.

An annual reduction of 123 tonnes CO₂ — equivalent to planting roughly 5,900 trees, and supporting FDF Ambition targets and retailer sustainability requirements that increasingly determine supply contracts.

Common Misconceptions

What We Hear — and the Reality

Myth
“Our fill accuracy issues are mechanical, not electrical.”
Reality
If your filling accuracy varies throughout the day or correlates with compressor cycling, it’s likely voltage-distortion related. Servo drives and load cells are sensitive to THDv above 5%. Many F&B manufacturers discover that “mechanical” accuracy issues disappear when power quality is corrected — saving on both giveaway and maintenance.
Myth
“We’re already under margin pressure — we can’t invest in electrical infrastructure.”
Reality
Margin pressure is exactly why this matters. At 10–25% energy savings, power quality correction delivers one of the highest-impact operational improvements available. That’s margin improvement from day one, without changing your products, processes, or headcount.
Myth
“Our retailer audits don’t cover power quality.”
Reality
Not directly — but they increasingly cover sustainability performance, energy efficiency, and carbon reduction. Tesco, Sainsbury’s, and M&S all require suppliers to demonstrate progress on emissions. 123 tonnes of annual CO₂ reduction is a concrete, verifiable contribution to those requirements.
