The automatic pre-fill leak detector tests empty bottles and containers for leaks before they reach the filler. It uses the pressure decay method to find pin-holes in moulded bottles and containers.


Key Features

  • Detects pin-holes as small as 50 microns.
  • Low power use: [50 W or 500 W;].
  • Continuous conveying, with no stoppers.
  • Runs on a safe 24 V DC control voltage.
  • Quick changeover between SKUs.
  • Stored recipes for each SKU.
  • PLC control with a touch-screen HMI.
