Automated Leak Detection Systems

Automated Leak Detection

At ALPHR Technology, we design and build bespoke pressure decay leak detection test machines. We integrate the most appropriate technology from industry-leading OEMs to provide high-accuracy measurements with the associated improvements to accuracy.

With 30 years of experience to call on, we have provided systems to clients in multiple sectors, including Automotive, Medical, HVAC, and Defence.

Collaborative Leak Detection Equipment

Our collaborative methodology enables us to provide pressure decay leak testing systems from a standalone test station to complete assembly lines with multiple leak detection machines fully integrated. Systems can be manual, semi, or fully automated to meet our clients’ requirements. And exciting times are ahead… As part of the Indutrade group of companies, ALPHR Technology and Nolek have joined forces to provide the best leak detection solution available worldwide. ALPHR is now an official supplier of Nolek leak test solutions and we are able to supply to our clients worldwide. The partnership builds on ALPHR’s 30+ years’ experience in automation and Nolek’s reputation for providing world-class leak detection instrumentation. ALPHR can offer turnkey leak detection solutions utilising Nolek leak testers, from standalone machines to fully integrated rotary and palletised solutions. The broad range of Nolek instrumentation ensures ALPHR can provide the perfect solution whilst offering our clients a single point of contact for support and calibration.

Frequently Asked Questions

What is automated leak detection?

Automated leak detection is the process of using machines and sensors to identify leaks in components or systems without manual inspection. Our systems use pressure decay testing, which measures pressure changes over time to detect even the smallest leaks with precision.

Pressure decay testing works by pressurising a sealed part, then isolating it and monitoring the pressure over a set period. A drop in pressure indicates a leak. It’s a reliable, non-destructive method used widely in automotive, medical, and industrial applications.

  • Higher Accuracy: Detects micro-leaks with minimal false positives
  • Repeatability: Consistent results across every test cycle
  • Improved Safety: Reduces operator handling of hazardous or sensitive components
  • Faster Testing: Increases throughput in production environments
  • Data Logging: Supports traceability and compliance
  • Lower Costs: Reduces rework, product recalls, and quality failures

Our solutions are used across:

  • Automotive: Brakes, fuel systems, oil pumps, headlights
  • Medical: Inhalers, syringes, sealed enclosures
  • HVAC & White Goods: Boilers, valves, heat exchangers
  • Defence & Industrial Manufacturing: Castings, solenoids, mission-critical components

Yes. ALPHR offers modular systems that can be installed as standalone test stations or fully integrated into rotary tables, palletised lines, or robotic cells. Systems are available in manual, semi-automated, or fully automated configurations depending on your needs.
