35 Years of Continued Excellence in High Speed Automatic Inline Leak Testing for Filled Aerosol Can Leak Testing

All our Leak Testers for filled aerosol cans are officially certified since October 2008 to be fully compliant to the ADR 2007 and FEA directive. (Hot Water Bath Alternative).

Bautz Engineering’s AeroFid® family of Micro Leak Detection Systems for filled aerosol cans offers over 35 years of proven, very reliable, economical and practical solutions to achieve immediate production savings and improved safety and quality by eliminating bubble detectors and water bath operators. In addition to our Water Bath Alternative, the complementary water bath test method with partially submersed cans generates accurate data to be easily and consistently gathered as an integral part of a quality management system to force improvements in quality and in the supply chain.

Reduced Risk while Increasing Safety

  • Performing automatic leak testing removes the chance that faulty cans remain in production and end up in storage and/or being ordered into transportation

Maximized Production while Cutting Down Material Waste

  • Very easy to use leak analyzer provides instant information to faulty can rejection and fault patterns

Ensured Quality and Regulatory Compliance

  • Optimize production output
  • Avoid product recalls

Features, all Versions:

  • Complies with ADR 2007, recent European EN 60079 Aerosol Directive and with United Nations Standard UN/SCETDG/INF.93
  • Unusually long maintenance intervals, 12 months in average, therefore unmatched low maintenance cost
  • No sample air filter change. Automatic sample filter back purge is performed after every detected leak
  • No problems with fogging mirrors, windows and reflectors as used in optical detectors, or faulty head chamber seals or contaminated sensor heads
  • Free scrolling cans safely pass the probe section which is automatically cleaned after each detected leak
  • Maintenance free sensing barrier to be calibrated once every year down to once every day. One daily zero check. Machine completely calibrates in less than 10 minutes
  • Very low running cost, only a small fraction compared to a hot water bath
  • Environmentally safe, no polluted water or air, very low electric energy consumption
  • Standard capacity from 60 up to 300 cans per minute. High speed versions available to test up to 500 cans per minute
  • Height adjustable for all available can heights
  • Based on a time proven high speed detector technology which we use for over 38 years in leak detection for filled aerosol cans
  • No hassle with time consuming multi- head calibration,
  • Quality control and assurance; The production records and calibration records are stored and printable via USB port, including calibration report
  • Smallest over all foot print industry wide. Space requirement less than 1 m2. It fits into virtually any conveyor line. No bulky control unit needed. All controls and displays integrated in main unit
  • Highly reliable, low cost of investment and ownership, easy to operate, low maintenance Detect micro leaks at room temperature. No heat or vacuum needed
