Compressed air is air that is pressurized and condensed. Just like regular air, compressed air consists mostly of nitrogen, oxygen, and water vapor. Compressed air is useful as a propellant and energy source in areas where it may be difficult or dangerous to source other power or as blowing “active” air. When used as an energy source, compressed air can power tools and production equipment. Tools and equipment powered by compressed air, can be found in various applications across industries such as construction, tire service, mechanical repair, factory production, industrial processes, and vehicle safety systems. Amusement Park rides, such as roller coasters, and ski lifts use air-powered brakes, and hotels use compressed air to control elevators. Active air provides a steady supply of air when needed for tasks such as aeration or for medical use, in which case, it must be clean, dry and contaminant free.

Compressed air has been described as the fourth utility and is a popular energy source because it’s light and easy to move, energy efficient, safe, versatile, and cost-effective. It’s non-combustible and there are no dangerous exhaust fumes or other harmful by-products. Compressed air plays an integral role in the production of cars and is also widely used in the food and beverage industry. Common uses for air in this industry include air knives, product handling, food machines, packaging, and fluid pumps. It accounts for about 10% of the global energy currently used.

There are many types of purities and mixtures available that cater to the varied uses of compressed air. From blowers and dryers to food & beverage processing, we have the years of experience to provide and consult for your needs.

Compressed air for your industry and application

Argon (Ar) is the most abundant of the seven noble gases and is the third-most abundant gas (at 0.934%) in the Earth’s atmosphere after nitrogen and oxygen. It’s odorless, colorless, nonflammable and is almost completely inert. It does not combine with other elements except under extreme conditions and its nonreactive nature plays a factor in its many uses.

Argon’s lack of reactivity makes it particularly useful in the production of reactive elements and compounds because it establishes an atmosphere devoid of oxygen, minimizing the purity contamination for resulting metals and crystals during oxidation. It is manufactured for industrial uses by the process of fractional distillation, which separates Argon from Oxygen and Nitrogen in their liquid states.

Most used in the metal industry for metal production, processing, and fabrication, it can be used as a pure gas for certain shielding, blanketing, annealing, and hot isostatic pressing applications. It can also be used as part of a mixture with other gases, in particular carbon dioxide, oxygen, nitrogen, hydrogen or helium, depending on the process and material. Argon is used in every day household objects such as incandescent light bulbs and energy efficient windows, and it also plays a very important role as a purge gas in the production of solar panels. Often used as a preservative for both food and historical document preservation, Argon has no impact on the environment and doesn’t harm aquatic life.

Carbon dioxide (CO₂) is a colorless, odorless gas that naturally occurs in the earth’s atmosphere. It is a dense inert gas that, when combined with argon, is used as a shielding gas in the welding process. Uses for carbon dioxide also include controlling pH levels in paper manufacturing and wastewater treatment and increasing yields in cultivation through the acceleration of natural cycles of photosynthesis.

Greenhouse gas emissions are an environmental concern. Carbon removal initiatives, such as direct air capture, extract carbon dioxide from the air and funnel it to be stored or reused by various industries. Green dry cleaning, with carbon dioxide, is environmentally friendly and replaces toxic cleaning solvents and chemicals like perchloroethylene and chlorine-based mixtures.

In its solid form, carbon dioxide is manufactured into small pellets for dry ice blasting, miraculously blowing away soot, smoke, paint, and excess buildup from coffee roasting machines and commercial kitchen appliances. Dry ice is made when cryogenic carbon dioxide is injected into a holding tank where it can be frozen to its desired temperature of -109 degrees Fahrenheit. Cleaning with carbon dioxide gas applications – both liquid and solid – can, realistically, be an environmentally friendly alternative to cleaning applications that use harsh chemicals that contaminate natural bodies of water through wastewater runoff.

Carbon Dioxide plays a significant role in food preservation and transport. Food distributors use dry ice for transportation, as it turns from solid to gas, without liquifying. This sublimination prevents water and residue from accumulating. These blocks are sanitary, food-grade and FDA approved. Beverage companies rely on it to create bubbles, but also to move product between tanks or to kegs and cans. Carbon Dioxide maintains beverage freshness, taste and color and prevents unwanted oxidation and premature fermentation at breweries and wineries.

Carbon dioxide supplies through RMA are offered in a variety of sizes for a variety of systems.

The lightest element in the periodic table, hydrogen (H), is used for weather balloons, processing petroleum products, glass production, and heat-treating furnaces for steel production. As a highly flammable gas, Hydrogen is commonly used in a variety of chemical processes, such as hydrogen fuel cells to power cars and in fuel celled forklifts. Hydrogen’s popularity is increasing because it’s reliable, versatile, and can be produced in a variety of ways.

Hydrogen has only one proton and one electron, making it the simplest element and is considered a clean and renewable resource. It’s not toxic to human health, as no harmful byproducts are released into the atmosphere.

Hydrogen comes in a variety of “colors.” What this means exactly, is that hydrogen manufacturing methods of separating hydrogen from various compounds (water, ammonia, methane, etc.), and the emissions that result thereafter, are labeled as three main color distinctions: brown, green, and blue.

Brown hydrogen – which comprises 95% of hydrogen production – is the byproduct of fossil fuels. Steam reforming and gasification is the separation of hydrogen atoms from carbon atoms in either natural gas or coal production. During this process of gasification, carbon dioxide emissions are high.

Electrolysis is the process in which an electrical current is used to split water molecules into hydrogen and oxygen. When hydrogen is harvested, only oxygen is left over. The lack of Co2 emissions makes this production method green.

Blue hydrogen is the capture and storage of hydrogen during steam methane reformation, which causes some, but reduced, carbon dioxide emissions.

Mixed gases are a wide and diverse group of products developed for use in specific industries for customized applications. A gas mixture is defined in a molar gas fraction, by percentage, parts per thousand or parts per million. Though gas mixtures are used in many industries, these are common applications in the medical, food and beverage, and welding industries.

Nitrogen (N), a colorless, odorless, tasteless gas, is the most common element in our atmosphere at 78%. It’s a component of all living matter, including water, soil, plants, and the human body. It accounts for about 3% of human body weight. Nitrogen has many useful applications in both its gas and liquid forms. One fun fact about nitrogen is that it’s responsible for the Aurora Borealis or Northern Lights’ purple color! When solar wind stimulates nitrogen atoms, the result is the purple and blue-colored lights emitted when the atoms decay.

Nitrogen is unique in that it can be used to prevent fires, but is also used to make explosives. In its natural state, Nitrogen is inert. However, if isolated or harnessed (as in the case of making explosives), it can release a large amount of energy. On the other hand, Nitrogen fights potential fire hazards by eliminating one point in the fire triangle. As a purging gas, its inert nature is denser than oxygen. By removing oxygen, with only heat and fuel remaining, nitrogen eliminates fire’s ability to ignite and thrive.

A requirement for most life on earth, oxygen (O) is one of our atmosphere’s most plentiful elements. A particularly reactive gas, oxygen easily binds to a large variety of elements and compounds to form oxides, requiring inert gases to displace it or prevent contact with surfaces and other gases.

Oxygen’s usefulness stretches across a wide range of industries. In hospitals, clinics, and other health and homecare practices, oxygen is used in resuscitation, surgery, and a variety of therapies to promote better quality of life. Humans aren’t the only ones who benefit from oxygen – fish hatcheries, zoo animals, and animal clinics all utilize this diverse gas to mimic natural habitats, growth, and recovery. In a radically different use, the industrial environment uses oxygen for its combustion properties – making flames hotter and the cutting and braising of metal easier and more efficient.

To better serve your needs, RMA sells oxygen at a variety of purity levels and with a variety of systems. Sold in various sizes of bulk cryogenic oxygen tanks or high-pressure oxygen cylinders, liquid levels are monitored remotely while trucks are deployed when levels begin lowering, and you can rely on a consistent schedule of refills of cryogenic oxygen tanks to ensure your oxygen supplies remain abundant.
