    AI Overview
    A Plate Heat Exchanger (PHE) Helium Leak Detection System Unit is a specialized industrial testing tool designed to identify minute leaks—down to

    —in the plates or gaskets of heat exchangers by using helium as a tracer gas. These systems are essential for validating the structural integrity of PHEs in critical applications like nuclear power, cryogenics, and chemical processing, typically operating in vacuum or pressure-decay modes. 
    Key Components of a Helium Leak Detection Unit 
    • Mass Spectrometer Detector: The core component that ionizes gas molecules and specifically detects helium.
    • Vacuum System: High-performance vacuum pumps (roughing and turbomolecular pumps) to create the necessary vacuum for sensing.
    • Gas Handling Module: Manifolds for supplying helium (tracer) and removing air.
    • Control/Interface Unit: Software to monitor leak rates and provide pass/fail feedback.
    • Probe (Sniffer): Used in "sniffing" mode to detect leaking helium from pressurized exchangers. 
    Common Testing Methods 
    1. Vacuum Method (Inside-Out): The PHE is enclosed in a vacuum chamber, evacuated, and then filled with helium. Any leak allows helium to escape and be detected by the mass spectrometer.
    2. Pressure Method (Outside-In/Sniffing): The PHE is pressurized with helium, and a "sniffer" probe is moved along the plates and gasket seals to find escaping helium. 
    Top Manufacturers & Systems 
    • EIT International: Hexteq system (specifically for PHE integrity).
    • Inficon: LDS3000 Helium Leak Detector.
    • MSE PRO: High-sensitivity helium leak detectors (typically

      ).
    • Pfeiffer Vacuum: Adixen ASI 35 series. 
    Advantages of Helium over Dye Testing 
    • Higher Sensitivity: Detects much smaller leaks.
    • Non-Destructive: Does not damage the gasket seals.
    • Rapid Results: Fast test time (often

      <2
       seconds response time).
    • No Residue: Clean testing method with no subsequent cleanup required. 
    These units are crucial for sectors requiring zero-leak tolerance for safety and performance reasons, such as pharmaceutical or nuclear industries.

        Hydraulic leak testing is simple & accessible but won't detect micro cracks, only large visible leaks. Pressure must be high.
