    A-Coil & Slab Heat Exchanger and HVAC Components Leak Test ...
    Automated Helium Leak Detection Facilities for automotive expansion valves use high-sensitivity vacuum chambers to detect microscopic leaks after brazing, ensuring HVAC system integrity. These systems, often operating in parallel for high throughput, charge components with helium to identify faults, allowing for automatic, precise, and efficient quality control. 
    Key Features and Capabilities 
    • High Sensitivity: Systems can detect leaks below
      1
      ×10−6
      mbar L/s, crucial for detecting minute defects in automotive components.
    • Automated Process: Units are loaded, evacuated, charged with helium, and tested automatically, with failed parts often automatically diverted for repair.
    • Parallel Testing: Using multiple chambers (e.g., dual stations) enables continuous flow and increased production volume.
    • Helium Recovery: To manage costs, advanced systems include helium reclaim technology to capture and reuse the tracer gas.
    • Comprehensive Testing: These facilities often combine pressure decay tests for larger leaks followed by hard vacuum helium tests for fine leaks.
