Aerosol Can Micro Leak Detectors for the water bath alternative, verified by Burgoynes for full compliance

Aerosol Can Micro Leak Detectors to mount after the hot water bath to high speed test monoblock aluminum cans
for micro leaks


To meet today's requirements on new and updated aerosol can filling lines, drastically increased standards on product safety and quality may make changes in the aerosol filling industry necessary.


Today, the AeroFid family of aerosol can leak testers are the most widely installed systems throughout the industry. They are an ideal solution to be applied as a fully compliant water bath alternative or as a high speed leak detecting solution in addition to existing water bath systems. Whatever your needs might be, we will find a tailored solution to fulfill your requirements.


J.U.M.'s fast leak analyzer technology is exclusively used in Bautz Engineering's Family of Micro Leak Detectors for filled aerosol cans. Our sensing technology drastically improves the current water bath system for detecting leaks faster and more accurately on aerosol filling lines during the manufacturing process. Our leak detectors are in full compliance with all current EU and UN regulations. They lead to significant gains in the production efficiency and improve health and safety and greater risk of management in the transportation of aerosols. They have high potential to be applied across very many aerosol production lines worldwide.

These high speed Aerosol Can Micro Leak Detectors are designed to be applied as part of the verified current water bath alternative. They are also used to leak test aluminum cans after a high speed hot water bath. They detect all LPG propellants, AP70 (C3/C4 blend), ISO-pentane, n-pentane, DME and any other hydrocarbon mixtures, including HFCs like 134A, 152A, 227EA, R134A/R152A-Blend and HCFCs like 142b and others. With 2.0 x 10-3 mbar.l.s.-, which converts to 1x2 mm bubble/sec and smaller, the detected leakage rates are in full compliance with all currently existing regulations.


While using only one sensing barrier the AeroFid family of micro leak detectors avoids critical and expensive multiple sensing heads for testing up to 250 cans per minute. For up to 500 cans per minute only two sensing barriers are used and the footprint is only slightly larger.


The performance of current hot water-bath systems for one peace aluminum cans will be drastically improved by applying our proven technology. Leaking cans are automatically rejected by the integrated mechanism. All that at a total foot print of only 900 X 900 mm.


During the past 12 months 18 machines were installed at different aerosol fillers throughout the UK. The array of leak detectors currently installed and in use spans our 3 basic versions from up to 80 cans per minute, 120 cans per minute to 250 cans per minute. With the exception of three machines which are used after the hot water bath for aluminum cans, all other machines are used in compliance with the hot water bath alternative.


Features and Benefits Quick Overview:

  • Wide dynamic range. Rapid detection of all hydrocarbon propellant gases and HFCs.

  • One calibration gas for all detectable propellant gases

Here is a summary about the compliance available from the 2008 Bourgoynes Verification Report:

  • The machines AeroFid-200, AeroFid-100 and AeroFid-60, as supplied by Raupack in the UK and by Bautz Engineering in Germany and other countries fulfill the requirements of recent UN/SCTDG/25/INF.93/ FEA regulations and the ADR 2007/ 2009 regulations for micro leak tester for filled aerosols. The machines are officially certified as the testing part of Water Bath Alternative method to detect leaks of 2.0 x 10-3 mbar.l.s.-1 of all hydrocarbon based propellants including all HFA and CFC propellants.., or smaller .

  • The machine has sufficient controls in place so as to present minimal risk of explosion.

  • Presenting no additional zoning requirement to its environs, and having an internal zone classified as non hazardous.

  • The machine can be considered as complying with the BAMA standard.

The AeroFid-60 tests up to 80 cans per minute. This compact, over the conveyor machine houses the high speed leak analyzer, the control panel with touch screen display and the  zero air generator. Our long standing, fast responding Model 22B hydrocarbon propellant sensor automatically extracts one sample at a time from the head and valve area of each individual aerosol can. The cans freely scroll through sensing area. Immediately after a leak was detected, the faulty can is rejected from the conveyor. For speeds above 80 CPM, per minute our AeroFid-100, AeroFid-200 or AeroFid-500 should be considered.
The AeroFid-100 tests up to 120 cans per minute at a footprint of less than 1 sqare meter. This compact, over the conveyor machine houses the high speed leak analyzer, the control panel with touch screen display and the  zero air generator. Our long standing, fast responding Model 22B hydrocarbon propellant sensor automatically extracts one sample at a time from the head and valve area of each individual aerosol can. Jam controlled by a star wheel or feed worm, the cans freely scroll through sensing area. Immediately after a leak was detected, the faulty can is rejected from the conveyor. For speeds above 80 CPM, per minute our AeroFid-100, AeroFid-200 or AeroFid-500 should be considered.
The AeroFid-200 tests up to 250 cans per minute also at a footprint of less than 1 sqare meter. This compact, over the conveyor machine houses the high speed leak analyzer, the control panel with touch screen display and the  zero air generator. Our long standing, fast responding Model 22B hydrocarbon propellant sensor automatically extracts one sample at a time from the head and valve area of each individual aerosol can. Jam controlled by a feed worm, star wheel or feed worm, the cans freely scroll through sensing area. Immediately after a leak was detected, the faulty can is rejected from the conveyor. For speeds above 80 CPM, per minute our AeroFid-100, AeroFid-200 or AeroFid-500 should be considered.
