Witt has released an upgraded version of the Leak-Master Mapmax – which can reach the industry best of 15 cycles per minute when testing MAP integrity of a packaging line.

The Leak-Master Mapmax enables non-destructive detection of even the smallest leaks using CO2 as a trace gas, and integrates seamlessly into any packaging line. Truly unique, it is able to check the entire volume of a line for leaks, contact-free and in a non-destructive manner. “With up to 15 cycles per minute, it is unrivalled. Not even one single leaking package gets to the customer”, says Sebastian Lehmann, Product Manager. “Besides single packaging, even shipping cases and entire boxes can be tested.”

A vacuum in the Mapmax test chamber creates pressure differences between the packaging and the chamber. Even the smallest leaks in the packaging allow gas to escape and this is detected by highly sensitive and ultra-fast sensors. The Witt technology focuses on the detection of carbon dioxide leaks as this gas is already present in most inert gas packaging avoiding the use more costly helium or hydrogen is not required.

With the newly introduced 2015 version, Witt also introduces a number of improvements. The most important innovation - the checking of small volume packages with low gas content such as sliced products has been further improved by means of an optional dynamic area compression within the chamber. Moreover, the machine is now also equipped with a welded stainless steel frame that offers significant vibration stability. The new vacuum pump requires low maintenance and does not produce any heat.

If, despite this, the machine still needs to be checked, the new design with easily removable access lids allows most maintenance tasks to be conducted during operation, without having to stop the entire production line. Thanks to quick release fasteners, wearing parts such as filters can be replaced within seconds. Even the new, high-quality conveyor technology which is characterised by two synchronised belt conveyors, has received a technical upgrade. These conveyors transport the product through the test chamber (with different sizes available).

Furthermore, one can recognise the new Mapmax at one glance: The switch cabinet and other elements which, until now, were only add-on parts have been compactly integrated into the system’s new hygienic stainless steel housing. This not only simplifies operation but the user can now also enter data through an enlarged colour touch screen. Optional barcode reader can easily be attached. No extensive training is required to master the user interface, the product operation nor the outputs. The Mapmax can be connected to the company’s electronic network via Ethernet to enable, for instance, controlling and data logging. If a leakage is detected, potential-free contacts switch upstream and downstream systems such as alarms and the machine stops.

Leak testing, with no errors, is more important than anything else because it gives 100 % peace of mind - no returned goods, no reputation damages.

“Thanks to these benefits, the Mapmax will pay off within a short time”, says Lehmann. On the website www.leak-master.net, which has been specifically created for this purpose, Witt offers further information about this new model and its smaller sister models.

With its gas mixing and analysis technology, Witt has been at the forefront since the very beginning of industrial inert gas packaging. This enabled the company from Witten, Germany to become a global market leader. The Leak-Master product range has contributed immensely to this - powerful systems for precise, fast and non-destructive leak detection and sealed-seam testing.
