Acoustic Imaging & Compressed Air Leak Detection Services
Identify, locate and quantify compressed-air, gas and vacuum leaks using advanced acoustic imaging technology — without interrupting plant operations.
Singh Isotech helps industrial facilities locate compressed air, gas, vacuum and electrical faults using advanced acoustic imaging technology. Our surveys identify, quantify and prioritise leaks without shutting down operations, helping reduce energy costs and improve reliability.
- Many facilities lose 20–30% of compressed air through leaks — identifying and repairing them can significantly cut energy waste
- Can identify early signs of electrical discharge before they develop into more serious failures
- Zero downtime — testing happens while your plant keeps running
- A report your maintenance team can act on the same day
Why a Leak Survey Pays for Itself
Depending on operating pressure and compressor efficiency, even a small compressed-air leak can waste thousands of units of electricity each year and cost lakhs of rupees annually. A leak this size is nearly impossible to hear over a running plant, so it stays hidden until an air system audit or the electricity bill flags it.
Our acoustic inspection equipment picks up the ultrasonic hiss a leak makes, long before a person could hear it, and turns that sound into a colour-coded image pointing straight at the leaking joint or valve — no soap bubbles, no guesswork, no stopping the line.
Every leak found during the ultrasonic inspection is logged with a decibel reading, an estimated annual cost, and a repair-priority ranking, so your team fixes the costliest leaks first — not just the loudest ones.
Systems We Test
The same acoustic camera works across almost any pressurised or electrical system, not just compressed air:
- Compressed air lines, fittings and pipelines
- Gas systems — nitrogen and CO₂
- Vacuum systems for packaging and process lines
- Pneumatic cylinders and control-air circuits
- Steam traps and valves
- HT/LT panels and switchgear (partial discharge)
- Bearings, motors and gearboxes (mechanical wear)
Beyond leaks, the same technology catches early-stage electrical discharge and mechanical wear — problems that stay invisible until they cause an outage or a breakdown.
How the Survey Works
- Scoping call — we learn your facility size, equipment list and problem areas
- On-site scan — our team walks the facility during normal operating hours
- Data analysis — every flagged sound is classified as a leak, discharge or mechanical fault
- Reporting — you receive images, severity levels and cost estimates in rupees
- Rectification support — we connect you with our vendor network if needed
- Post-repair check — we re-survey tagged points to confirm the fix worked
What's in Your Report
Every survey ends with an annotated set of findings, not a PDF full of jargon:
- Annotated photo showing the exact leak or fault location
- Decibel severity rating
- Estimated leak rate and yearly cost in rupees
- Repair-priority ranking
- Optional post-repair verification note
Ask for a sample report before you book — happy to share one.
What's Included in Every Survey
- Detection of compressed-air, gas and vacuum leaks
- Acoustic images showing the exact leak location
- Leak identification and physical tagging
- Estimated leakage rate and annual energy-loss calculation
- Repair-priority classification
- Detailed photographic report
- Post-repair verification survey
- Testing during normal plant operation — non-intrusive, no shutdown
- Coverage of pipelines, valves, fittings, joints, hoses and pneumatic equipment
How the Technology Works
Think of it as a visual ultrasound for your plant. A microphone array picks up ultrasonic frequencies completely inaudible to the human ear, then overlays that sound data onto a photo so a technician can point, click and instantly spot the source. What used to take a technician several days with a handheld probe, a single scan can now cover in an afternoon.
Indian conditions — dust, humidity and voltage fluctuations — accelerate insulation deterioration, making acoustic inspection valuable for catching early-stage wear before it becomes a compliance issue.
Acoustic Imaging vs Thermal Imaging
The two get confused often, since both use a handheld camera and produce a colourful overlay. They catch different physics, which is why we recommend using them together.
Acoustic Imaging | Thermal Imaging |
Detects ultrasonic sound | Detects infrared heat |
Finds air and gas leaks | Finds overheating components |
Catches early-stage partial discharge | Catches faults already generating heat |
Works before temperature rises | Works after heat has developed |

Signs You Need a Survey
Usually there are warning signs before a full failure. If any of these sound familiar, it’s worth booking a survey:
- Compressor electricity bills keep climbing even though production hasn't changed
- Your air compressor cycles on and off more often than it used to
- Unexplained electrical tripping or nuisance trips in a panel
- A suspected HT panel or switchgear issue you can't visually confirm
- Steam traps or lines losing pressure with no obvious cause
- Ageing switchgear or HT/LT panels that haven't been tested recently

Frequently Asked Questions
What is acoustic imaging used for?
It detects and visualises compressed air and gas leaks, partial or corona electrical discharge, and mechanical faults like worn bearings — all by capturing ultrasonic sound that’s invisible and inaudible to people.
How is acoustic imaging different from thermal imaging?
Thermal imaging detects heat; acoustic imaging detects sound. Early-stage partial discharge often shows up acoustically well before it generates enough heat for a thermal camera to catch — the two work best together.
Does the survey require a plant shutdown?
No. It’s non-contact and non-invasive, so audits happen on live, running systems with no downtime.
How much can I save by fixing compressed air leaks?
Many facilities lose 20–30% of compressed air through leaks. Identifying and repairing them can significantly reduce energy waste and lower annual electricity costs.
Can this detect electrical faults before they cause a fire?
Yes. Partial discharge and corona detection can identify early signs of failing insulation and loose connections before they escalate into arc flash events.
How often should I get a survey done?
Most facilities benefit from an annual audit; high-risk environments with continuous compressed-air use or ageing HT/LT panels may want to audit twice a year.
