Various technical applications

WITT inline gas analysers can be delivered as an integrated version in gas mixing systems or as separate analysing systems. For highest safety requirements an emergency cut-off can be activated. For example when the hydrogen concentration reaches over 5 % the hydrogen supply can be isolated and the system flushed with 100% nitrogen. Operation is easy via a touchscreen electronic control unit GC50.

Numerous interfaces and connections such as Ethernet, 4-20 mA or potential free contacts make integration into existing systems simple.

WITT inline gas analysers guarantee high efficiency and safety - so no leaky packaging gets shipped. The inline gas analysis starts directly during the packaging process and offers a continuous checking of the supplied protective atmosphere. This quality assurance is the perfect complement to subsequent checking, increases process quality and allows the reduction of random checks. This reduces personnel costs and the amount of packaging waste. Depending on the packaging machine, even the gas consumption and thus the costs can be significantly reduced.

The WITT product range includes suitable inline analysers both for form, fill and seal machines as well as for thermoforming machines and tray sealing machines.

In thermoforming packaging machines or tray sealing machines, a vacuum is first generated in the packaging chamber, thus removing the air. In the next step, protective gas is supplied and then the tray is sealed. WITT also offers the MAPY VAC analyser, which is specially designed for these machine types.

In each cycle of the packaging process, a sample is taken when the protective gas is filled into the packaging and analysed within seconds. The testing process is fully automatic. An alarm is triggered when limit values are exceeded. The user can intervene directly and make changes to the process. The quality of the MAP packaging process is 100% assured and continuously optimised.

Owing to nature of the process, the amount of gas used in these packaging machines cannot be reduced. Nevertheless, inline gas analysis is very important for the most effective quality management. The sampling frequency and the associated personnel costs can be reduced, and the packaging quality increased at the same time. This is important for achieving the target best-before date and thus for securing your customer relationships in the long term.

In flow packaging machines, protective gas is continuously fed into the film tube during packaging. The MAPY LE online gas analyser is the key to maximum efficiency: with a lance, a sample is continuously taken from every single pack and quickly analysed. As long as the oxygen value is below the set limit value, the quantity of the supplied protective gas is reduced via the gas mixer or a gas dosing unit. Only as much gas is used as is absolutely necessary for an optimum packaging result. Completely automatically. Human intervention is not necessary. The cost advantage is obvious: A reduction of gas consumption of up to 50 % is possible.

The inline gas analyser is operated intuitively via the touch screen of the electronic control unit. The devices can be flexibly integrated into existing systems via numerous interfaces and connections such as Ethernet, 4-20 mA or potential-free contacts. Retrofritting is also possible.
