Germany-based Gas safety equipment manufacturer Witt has launched the new ‘Pack-Vac’ that can be used for the non-destructive testing of nearly all types of packages, even for vacuum packs.
Pack-Vac is aimed at replacing leak detection systems which use trace gases. It does not require trace gas or even electricity, instead the only thing required is compressed air.
For leak detection, the package is placed into a testing-chamber filled with water. The headspace above the water level is evacuated using a venturi vacuum driven by compressed air. The package immersed in water starts inflating due to the vacuum and if there is a leak, air or inert gas it gets identified by a stream of bubbles. Thus, the tester visually recognises if and particularly where the product is leaking.
The operating costs of this testing facility are low because water and air are used instead of expensive helium. Moreover, the ‘Pack-Vac’ does not need extensive maintenance and can be drained sanitarily by a latch in the base. Also, there is no skilled personnel required due to the simple, intuitive handling.
