Leak detection system with vacuum attachment

A low cost, leak detection system that detects leaks in individual packages without the need for trace gases, can now be supplied with a special attachment to test vacuum packs for leaks.

Witt Gas Techniques, the Warrington, Cheshire based gas safety, control, mixing and analysis equipment supplier who recently launched 'Pack-vac' a low cost, leak detection system that detects leaks in individual packages without the need for trace gases, can now be supplied with a special attachment to test vacuum packs for leaks.

Pack-vac uses only water and compressed air to detect any leaks and is already an ideal alternative to the Belljar or conventional water tank method of testing non-vacuum packs and MAP.

With this new attachment the PAC-VAC can be used to test for leaks in vacuum packs found in many industries including food packaging, pharmaceutical packaging and cosmetic packaging as well as other industrial packaging.

The unit is very portable and is available with 6 different size chambers ranging from height 203mm x width 280mm x depth 203mm to height 508mm x width 813mm x depth 660mm.

It is extremely easy to use - the package is placed in the chamber filled with water and compressed air is applied at between 5 - 8 bar.

The immersed package inflates and any leak is indicated by a stream of bubbles The benefits of using 'Pack-vac' include test times of around 30 seconds, no calibration of the equipment is required, no special skills are required to use the equipment, it is simple to maintain and has an easy to clean Perspex housing, no electrical connections are required nor is there a need for a vacuum pump.

Carl Long, General Manager at Witt Gas commented: "Because Pack-vac can now test vacuum packs, it has opened up a new market sector for Pack-vac and because it is much simpler and easier to use than other systems for detecting leaks in vacuum packs, operators require very little training.
