Carbon Dioxide

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.

Primary Applications

Fire Protection
Food and Beverage
Cultivation

Carbon dioxide smothers fires by displacing oxygen needed for combustion. It also cools the burn area. While some extinguishers may leave a mess, CO2 fire extinguishers get the job done with little to no residue left behind. The elimination of cleanup is ideal if electrical equipment catches fire, making it ideal for class B and C fires. RMA also provides fire extinguisher cylinder refills and cylinder testing and requalification based out of our Salt Lake City branch.

On a larger scale of fire protection, carbon dioxide fire suppression systems are 24/7 hands-free configurations that cover entire facilities when a fire is detected. They can cover the interior surface area of an entire building with minimal mess, and suppression systems will not damage electrical panels or systems.

Perhaps one of carbon dioxide’s best-known uses is as a carbonation method for soft drinks, seltzer water, and beer. Carbonation is not its only purpose, as it also maintains a fresh taste and color throughout production, transfer, storage, and bottling.

Modified Atmospheric Packaging with carbon dioxide reduces oxidation and moisture, increasing shelf life in the food distribution industry. Displacing oxygen in food packaging, carbon dioxide eliminates the need for preservatives in foods, and ensures that food upholds its visual appeal, flavor, and texture, while locking in nutrients throughout the transportation and stocking process.

Sealing greenhouses, investing in additional lighting, and increasing water input is rarely enough to induce greater yields in the cultivation industry – however, carbon dioxide for cultivation is widely used to give plants a boost in nutrients. By increasing levels of carbon dioxide available to plants in controlled areas, growth rates may increase up to 30% depending on the vegetation and conditions.

Properly outfitted and ventilated greenhouses and grow rooms supplementing carbon dioxide for agriculture and medicinal plants, the frequency of dry periods is greatly reduced, and thriving plants may be harvested year-round.
