PBI-Dansensor, Glen Rock, N.J., developed a revolutionary new ‘smart’ gas mixer for modified atmosphere packaging (MAP).

The MAP Mix Provectus uses an entirely new operating principle to produce a compact, versatile and easy-to-use gas mixing system. The MAP Mix Provectus can be coupled to PBI-Dansensor’s latest gas analyzer, MAP Check 3, to provide constant monitoring and automatic adjustment of mixture and flow to achieve maximum efficiency.

This state-of-the-art MAP Mix Provectus uses the latest mass flow technology, which allows it to be housed in a small cabinet for greater versatility and a higher flow rate. The large amount of different gas mixtures typically used in MAP can be achieved with only two different MAP Mix Provectus models. Plus, the MAP Mix Provectus can deliver a flow of up to 1,500 liters per minute.

Different MAP Mix Provectus models can mix either two or three gases. In addition, the units can store up to 10 different programs, allowing the operator to set parameters such as gas mix and outlet pressure, and so forth. A touch-screen display makes the MAP Mix Provectus simple to operate and contains the necessary connectivity for data logging control. This means, for example, that it can be linked into the packaging line’s process monitoring system, so that the quality manager can monitor factors such as total gas consumption, current gas flow and gas mix at any time.

The launch of MAP Mix Provectus coincides with the unveiling of PBI-Dansensor’s latest gas analyzer, MAP Check 3. This has a new 5-inch color touch screen for easy use, excellent connectivity for data logging and control through USB, Ethernet and Modbus TCP, and is delivered with PC software. MAP Check 3 allows operators to combine monitoring of gas content on a vertical or horizontal flow packaging machine with real time control of package flushing via an advanced GasSave function. For most manufacturers, this could translate into a 20–50% decrease in gas consumption.

Furthermore, MAP Check 3 is designed to operate seamlessly in tandem with the MAP Mix Provectus. The analyzer constantly monitors the gas mixture entering the packaging machine. If it detects a change in the oxygen level, it sends a signal back to the MAP Mix Provectus to make the appropriate adjustments of the gas flow. This feedback control ensures that the correct amount of gas enters the package at all times for maximum efficiency, consistency and quality assurance, therefore reducing waste and increasing cost savings.
