The Problem

Hospitals Are Uniquely Vulnerable to Power Quality

Hospitals combine the most demanding harmonic-producing loads (MRI/CT scanners, VFD-driven HVAC, UPS systems) with the most sensitive equipment (surgical lighting, patient monitors, infusion pumps). The harmonic distortion from imaging equipment ripples through the entire network, affecting systems clinicians rely on for patient safety.

What Causes It

When Your Most Expensive Equipment Is the Problem

MRI and CT scanners are among the largest harmonic sources on any hospital network. Their gradient amplifiers draw large, rapidly varying currents. HVAC (40–60% of hospital load) adds VFD harmonics. UPS systems contribute rectifier harmonics. The equipment that needs the cleanest power is creating the most distortion for everything around it.

Operating theatre power quality + Read more− Close

Theatres require ultra-reliable power with precise environmental control. VFD-controlled AHUs maintain positive pressure cascades (15–25 Pa above corridors) for infection control. Voltage distortion above 5% causes imperceptible lighting flicker that fatigues surgeons, monitor display artefacts, and electrosurgical unit performance variations. HarmoniQ filtering maintains THDv below 2% at the theatre distribution board.

The Solution

How HarmoniQ Works

HarmoniQ’s narrowband tuning technology cleans harmonic distortion from imaging equipment while stabilising voltage for sensitive clinical systems. Sampling 20,000 times per second, the system adapts to the dynamic load profile of a working hospital.

HarmoniQ Filter

Reduces THD below 3%. Extends UPS battery life by 30–50% and eliminates harmonic heating in critical HVAC motors.

Beyond the Bill

Clinical Quality, Equipment Life & NHS Net Zero

Clean power means better imaging reliability (MRI/CT worth $1.3–$3.8M each), fewer cancelled scans, extended UPS battery life, and reliable theatre pressure cascades.

A 500-bed hospital saves 216 tonnes CO₂ per year — equivalent to planting roughly 10,000 trees, and directly supporting NHS Net Zero 2040.

Common Misconceptions

What We Hear — and the Reality

Myth
“We’re an NHS Trust — we have no capital budget for this.”
Reality
HarmoniQ can be structured as a managed service (opex) funded entirely from guaranteed energy savings. This avoids the capital approval process and aligns with NHS framework procurement routes. The savings deliver a measurable Cost Improvement Programme (CIP) contribution from month one.
Myth
“Our imaging equipment has its own power conditioning.”
Reality
MRI and CT scanners have internal conditioning, but they’re also the largest harmonic sources on your network. Their distortion affects everything else — theatre UPS, patient monitoring, nurse call systems, and building services. HarmoniQ protects the network from imaging harmonics, not the other way around.
Myth
“We can’t risk any disruption to clinical services.”
Reality
Absolutely agreed — patient safety is paramount. HarmoniQ installs in parallel with zero interruption to clinical power. No circuits are broken, no loads are transferred. We provide a full method statement and risk assessment aligned to HTM 06-01 requirements before any work begins.
