When looking for specialized help with ultrasonic leak detection for an industrial compressed air system, you generally have two main routes: hiring an industrial compressed air service provider/distributor that offers turnkey auditing and repair, or bringing in a predictive maintenance / reliability engineering consulting firm that specializes specifically in non-destructive testing and energy audits.
1. Compressed Air Equipment Distributors & Service Specialists
These companies sell, install, and maintain compressors (brands like 
Atlas Copco, Kaeser, 
Ingersoll Rand, 
Sullair) and almost always employ certified technicians who perform comprehensive system audits and ultrasonic leak surveys.
- Local/Regional Air Compressor Houses: Local service companies (such as Compressed Air Systems or regional firms like Rocha Corp ) routinely conduct plant air audits. They use ultrasonic detectors to map leaks, quantify CFM losses/energy waste, and can often repair or replace faulty fittings, drops, and valves on the spot.[1][2]
- Major Manufacturer Service Divisions: Directly contacting your compressor's Original Equipment Manufacturer (OEM) local branch or authorized distributor is a fast track, as their technicians understand plant-wide pneumatic distribution flow.
2. Predictive Maintenance & Energy Audit Engineering Firms
If you want an independent audit or your plant is large enough to warrant a dedicated reliability team for a campus-wide survey:
- Industrial Reliability & NDT (Non-Destructive Testing) Contractors: Firms specializing in electrical and mechanical reliability asset management often offer compressed air ultrasonic testing as part of broader ISO-compliant plant reliability programs (encompassing vibration analysis and thermography).
- Utility-Backed Energy Auditors: Many local electric/utility companies offer subsidized or free compressed air leak audits because reducing air leaks yields massive immediate energy savings. Check with your utility provider's industrial account manager for certified vendor lists.
3. Doing It In-House (The Equipment Route)
If your maintenance team prefers to handle it internally rather than hiring an outside contractor, you can purchase industrial-grade ultrasonic leak detection kits:
UE Systems (such as their Ultraprobe kits like the UP100 or digital equivalents) is an industry benchmark for plant leak detection.
Amprobe (such as the ULD-400 series) offers robust, field-ready handheld ultrasonic detectors with parobolic attachments for high-noise factory environments.[1][2]
If you'd like to narrow this down, let me know:
- Your general geographic location (state or region)
- How large your facility or compressor setup is
- Whether you want an outside contractor to fix the leaks or just audit/find them for your own crew
I can help point you toward the most relevant type of local resource or approach.
SDT Ultrasound). If you prefer to train an in-house maintenance team rather than hire an outside contractor, these companies manufacture the industrial-grade ultrasonic gear and provide Level I/II certification courses for plant technicians.
