Our Trumix® Industrial series panels have been redesigned to include inlet regulators and filters with the intent to prevent over-pressurization and contamination issues that we’ve seen with industrial RMA repairs. Contamination and over-pressurization can cause irreparable damage to the internal components and panel. With this new industrial product line, we have also added a 3-year warranty on these panels to give you and your end user peace of mind for protecting your investment while maintaining our promised quality and precision.

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® 2000 Installation Instructions

Selecting a blend for your shield gas depends on your material and welding process. Having the correct blend for your shielding gas helps increase the penetration of the welds, reduces the number of defects in the welds, and helps block out any of the naturally occurring gases in the atmosphere like Nitrogen and Oxygen.

Common welding materials include mild steel, stainless steel, aluminum, copper, and cast iron which all can benefit from mixed gas. The most used gases are Carbon Dioxide and Argon, but we’ve also seen mixtures with Helium, Hydron, or Oxygen in small percentages to increase the heat and penetration of the welds. We’ve built thousands of industrial blenders, specifically for welding, with a variety of gases and blends. Our panels can work with any application, whether you are using MIG/MAG, TIG, Arc, or laser.


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.
