Our original Trumix® Industrial series panes are only available in tri-mix blends. All panels are built to order with custom inlet pressures.

McDantim recommends coalescing filters for each pure gas inlet. If filters are added at the time of panel purchase, McDantim adds a year to the panel’s original limited warranty.

Our panels are calibrated on a lab-grade mass spectrometer, ensuring the highest accuracy throughout the flow range. Each blender, regardless of its capacity, is guaranteed to maintain an accuracy of +/- 10% of the minor component or 2% full scale from 2 scfh to the panel’s maximum flow rate.

They can be mounted directly on an interior wall and plumbed in place. Additional customizable accessories include gas blend analyzers and low-pressure alarms. If you or your customer needs a specialty blend, panel, or solution, give us a call and we’ll design exactly what you need.


Trumix® 3-Gas Industrial Installation Instructions

Modified Atmosphere Packaging (MAP)


Mixed gases are imperative to the food processing and packing industry and the correct gas mix can transform the shelf life and presentation of your products.

Within the production process, mixed gas is vital for many key stages such as production, bulk distribution, retail, and final packing for consumers. Modified atmosphere packaging (MAP) can be hugely beneficial and there are several gas mixes required at different points of this process.


With MAP, different gases can play vital roles in product longevity. With unwanted processes like mold growth and oxidation both being a death sentence to packaged food, Nitrogen gas can be hugely beneficial in excluding Oxygen from food packs. Transversely, oxygen can help keep products, like cheese, fresh. For red or uncooked meat, a tri-mixture of Carbon Monoxide, Carbon Dioxide, and Nitrogen is a popular choice, as the mixture helps to keep the meat fresh and maintains the vibrant, red color.

With a McDantim Trumix® panel, successful MAP is achievable when applying the precise mixtures used in the flushing stage of the process. Using a burst or pulse filler? We offer buffer tanks in multiple sizes to fit your application.


While our Trumix® panels don’t require a storage tank to operate or mix gases to your required blend, sometimes it’s best for the life of the panel and the application to have a storage tank.

Modified Atmosphere Packaging (MAP) uses mixed gas to adjust the atmosphere either in a full space or in bursts to fill packages, extending the shelf life of certain foods. With burst filling, we recommend adding a surge or buffer tank with your Trumix® panel.
