    Supplying the Full Range of Fuel Gases to Suit Many Applications

    Fuel gases are comprised of a specialized group designed to be used for welding and cutting, power for transportation, and heat treating applications. These gases are derived for heat energy, and most of them are comprised – whole or in part – of hydrocarbons, hydrogen, carbon monoxide and oil vapors. Fuel gases are available in gaseous form. 

    Our experts have over 80 years of experience in the use of fuel gases and their applications. So not only are you getting the best product available, but the expertise and KnowHow™ to go with it. Whether you need to optimize the flame temperature and oxygen jet or to help manage the appropriate safety precautions, we are here for you every step of the way.

    C2H2

    Acetylene
    Acetylene (C2H2) is a colorless gas that is lighter than atmospheric air. It can be produced as a by-product of a reaction between water and calcium carbide. Acetylene is one of the hottest and most efficient of all fuel gases used in many industries. It is widely used in heating processes.

    H2

    Hydrogen
    Hydrogen (H2) is an odorless, colorless and tasteless gas that will burn with an invisible, clean flame. This gas is lighter than atmospheric air. Hydrogen is the only fuel gas that does not contain carbon and has the highest thermal conductivity of all gases, making it an ideal gas for many different industries and their needs.

    C3H8

    Propane
    Commonly known for its consumer use in gas grills, propane (C3H8) is a colorless and highly flammable liquified gas – although it has the lowest flammability range of any of the commonly available fuel gases. As a constituent of natural gas, it is obtained by refining and processing natural gas. Propane is heavier than air, with both a primary and secondary flash temperature. It is one of the main components in liquid petroleum gas (LPG) along with butane. As the ratios of these LPG gases vary from one supplier to another, the flame properties can also differ.

    Alternative Fuel Gases

    StarFlame
    StarFlame cutting fuel burns hotter than other fuel gases so that is cuts quicker. It is more economical and environmentally friendly, and is safer than acetylene and other fuel gases. Features of StarFlame include: a quicker start to steel ignition point at a lower cost, faster cutting speeds, cleaner piercings, minimal slag and weld-back from cleaner flame, significantly less smoke and soot, and reduced potential for torch backfire.

    Propylene
    Propylene (C3H6) is a colorless, flammable, liquefied gas with a faintly sweet odor. The heat release in the primary flame cone is slightly less than that of acetylene. This fuel gas also burns hotter than propane. When compared with acetylene, propylene offers greater safety as it can be utilized up to full tank pressure. It is well suited to being used at cold temperatures as it has a greater vapor pressure when compared with propane.

    Behind every package of fresh meat, bag of pre-cut salad, and bottle of craft beer sits an invisible guardian – specialized gas mixtures that preserve flavor, extend shelf life, and ensure product safety. At nexAir, we work with food processors and packagers throughout the Southeast to develop custom gas solutions that address the unique challenges of food production. Our approach goes beyond simply supplying cylinders – we become partners in your quality control process.

    The Critical Role of Gases in Food Preservation

    Food spoilage begins the moment a product leaves the production line. Oxygen fuels bacterial growth, accelerates oxidation, and triggers enzymatic browning. Carbon dioxide inhibits microbial activity. Nitrogen displaces oxygen and maintains package integrity. Understanding the precise balance needed for each food product requires specialized knowledge of both gas properties and food science. Our team works at this intersection, helping you determine the optimal gas mixtures for your specific products.

    Modified Atmosphere Packaging That Preserves Natural Quality

    Consumers increasingly demand fresh, minimally processed foods without artificial preservatives. Modified Atmosphere Packaging (MAP) allows you to meet these demands by replacing the air inside packaging with carefully calibrated gas mixtures. For red meats, we supply high-oxygen blends that maintain the bright red color consumers associate with freshness. For prepared salads and sliced produce, low-oxygen mixtures prevent wilting and browning without affecting taste or texture. Our custom MAP solutions help your products maintain their natural appearance and flavor profile throughout their shelf life.

    Ensuring Consistent Quality Through Precision Blending

    Quality control in food production demands consistency – consumers expect the same taste, appearance, and freshness with every purchase. Gas mixtures that vary from batch to batch can undermine this consistency. Our automated blending systems deliver precise gas compositions every time, eliminating the variability that can affect product quality. We regularly calibrate and certify our equipment to food-grade standards, giving you confidence that the gas touching your products meets the highest purity requirements.

    Technical Support When You Need It Most

    Production issues rarely happen during business hours. That's why our team remains available to help troubleshoot gas-related challenges whenever they arise. When a bakery customer noticed inconsistent product volume during an overnight shift, our on-call technician identified a pressure fluctuation in their carbon dioxide supply and quickly implemented a solution. This responsive support helps prevent quality control failures that could otherwise result in product loss and delivery delays.

    Partnering for Continuous Improvement

    Food trends, processing technologies, and packaging materials constantly evolve. We work with our food industry customers to regularly evaluate gas solutions against changing requirements and opportunities for improvement. Our technical team keeps you informed about innovations in gas applications that might benefit your operation. This collaborative approach helps you stay ahead of challenges and continue meeting the high-quality standards your customers expect.

    Maintaining quality control in food production requires vigilance, specialized knowledge, and reliable partners. At nexAir, we provide more than just industrial gases – we deliver application expertise, responsive service, and custom solutions that address the specific challenges of your food products. Contact our food industry specialists today to discuss how our gas solutions can strengthen your quality control program and help deliver the consistent product excellence your customers demand.
