Joint Leak Tester Announcement by J.U.M. Engineering

The 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 and gas cartridges must pass a rigurous test for a leak proof inspection before they become released for transportation.

For the past decades aerosol can fillers have relied on hot water bath testing to verify the integrity of their aerosol products. This technique is known to be using up energy resources, being very costly and disruptive to one's production.

Bautz Engineering's Automatic High Speed Leak Detection Systems for filled aerosol cans were the first in the market since 1983. They use J.U.M. Engineering's high speed Leak analyzer and reliably detect and reject leaking aerosol cans up 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, 134A, 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 in lower maintenance costs and higher operational reliability. With today's increasing variants of safety and quality standards required, Bautz Engineering's AeroFid Line of leak testing machines ensures current and future regulatory compliance.

Certified hot water bath testing alternatives, such as our AroFid-60, AeriFid-100 and AeroFid-200 lines of leak testers simplify and speed up the production process by eliminating the water bath and significantly reduce floor space, energy consumption and maintenance cost.


  • 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 reachable in the front of the machine, 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

  • 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 20 millisecond analysis time and faster

  • Up to 500 cans per minute

  • Automated rejection/can count/alarm

High sensitivity

  • 2 x 10-3 mbar.L.sec-1 leaks and much smaller leaks detected

  • On-Site serviceable and configurable

  • Onsite replaceable form parts

  • Easy customization

  • Lowest service and maintenance intervals for 12 months

  • No sample filters to be changed, no optics to be cleaned

  • No cell purge needed for 12 months due to high temperature system

  • Configured to operate in Zone 2 environments

  • Other applications available upon request like MDI's


In Early November 2010, the 15th and 16th aerosol can leak detector was sold and installed in the UK. Our recent installations make the AeroFid the most widely used micro leak detector to be applied for the hot water bath alternative throughout the aerosol industry
In September 2010, the Aerosol Congress in Rome was a great success. We had our AeroFid-200 leak tester on display an had the chance to demonstrate the performance at full speed. Our visitors were impressed of the accuracy and speed.

Burgoynes Report verifies leak detector compliance

The Verification Report describes how the AeroCan Leak Detector complies to the British Aerosol Manufacturers (BAMA) standard, including its safety and zoning requirements. It also details how the leak detector complies to the requirements of ADR 2007 for use as part of the water bath alternative.

First in the UK: AeroFid 200 Leak Detector installed at LMA Services.

This Bautz Engineering Aerosol Can Leak Detector which exclusively uses the model 22B leak analyzer by J.U.M. Engineering, is capable of testing up to 250 cans per minute, has been verified to comply to the requirements of ADR 2007 for use as part of the water bath alternative by Bourgoynes on Friday the 12th September, 2008.
