During the past decades aerosol can fillers have relied on hot water bath testing to verify the integrity of their aerosol cans. This technique is known to be using up floor space, energy resources and being very costly to one’s production; Our leak testers are officially approved to replace a water bath.

  • Hot water baths are a very expensive investments easily exceeding 180’000 Euro/Dollar and cause very high maintenance bills
  • They require a large footprint in typically space constrained areas
  • Maintaining the required water temperature of 122°F (50°C) requires a significantly high energy investment
  • Keeping up with the water bath causes extremely high maintenance requirements and routinely requires expensive chemicals to prevent corrosion and keep the water clean
  • We grant continuous leak monitoring systems at lowest maintenance costs and highest operational reliability
Aerosol Can Leak Testing

Aerosol Can Leak Testing

Bautz Engineering’s Automatic High Speed Leak Detection Systems for filled aerosol cans were the first in the market since 1983. They use our time proven high speed Leak analyzer and reliably detect and reject leaking aerosol cans from as low as 50 cans per minute up to a rate of 500 cans per minute.

The automatic detection process is continuous, contact-less and prevents product damage- and contamination. Our design grants the seamless detection of all hydrocarbon based propellants
including all LPG mixes, Butane, Propane, AP70 (C3/C4 blend), iso-Pentane, n-Pentane, DME all blends, including HFC, HFA, R134A, 152A, 227EA, R134a/R152a blend and HCFC’s like 142b, including the new HFO-1234ze. Air, CO2 and N2O Propellants are not detected. Continuous leak monitoring results at lower maintenance costs and higher operational reliability.

With today’s increasing variants of safety and quality standards in place Bautz Engineering’s line of leak testing machines ensures current and future regulatory compliance. Certified hot water bath testing alternatives, like our AeroFid-60®, AeroFid-100® and AeroFid-200® lines of leak testers significantly speed up and simplify the production process by eliminating the water bath and significantly reduce floor space, energy consumption and maintenance cost.

The current Aerosol Dispensers Directive by the the European Commission’s legislator (ADD), (UN ADR 2013, 75/324/EEC) mandates that aerosol dispensers and small receptacles containing
compressed gases like spray cans must pass a rigorous test for a leak proof inspection before they become released for transportation.


  • Automatic leak testing of filled cans in aerosol filling lines
  • Leak testers independently accredited to be a compliant hot water-bath alternative
  • Use our Leak testers as water bath alternative to guarantee compliant leak detection
  • Compliment your current hot water bath with our leak tester to guarantee compliant leak detection
  • Very small all over foot print of only 1 m2
  • All controls, data printer and displays to be operated in eye heighr in the front of themachine, no external control console used

Propellant Detection Flexibility

  • All LPG mixes, Propane, Butane, Propane/Butane, AP70 (C3/C4 blend), iso-Pentane, n-Pentane, DME (ll blends), HFC, HFA, 134A, 152A, 227EA, R134a/R152a blend and HCFC’s like 142b, including the new HFO-1234ze

Can Type Flexibility

  • Different can diameters and heights
  • Height adjustable Monitor collects sample from the upper crimp area and/or around the can and bottom
  • No product contamination of analysis system; Leaks are detected with sampling system being zero purged after each detected leak

Secure and Instantaneous Response

  • No rejection errors
  • Cans are automatically separated inside the machine and individually followed until the rejection of a leaking can
  • Compressed air pusher to remove faulty containers without disruption of the can
  • High speed/low volume sample delivery
  • Rapid analysis time, 20 milliseconds and faster
  • Up to 500 cans per minute
  • Automated rejection/can count/alarm

High sensitivity

  • 2.0 × 103 mbar L/s leaks and much smaller leaks detected
  • On-Site serviceable and configurable
  • Onsite replaceable form parts
  • Easy customization
  • Service and maintenance intervals of 12 months
  • No sample filters to be changed, no optics components to be cleaned
  • No cell purge needed for 12 months due to high temperature analysis system
  • Configured to operate in Zone 2 environments
  • Other applications available upon request like pharmaceutical MDI leak testing (since 1993), aerosol spray valve function tester, spray-head assembler and others
