About Us

Welcome to Giant CO2, Orange County's supplier for carbon dioxide (CO2), nitrogen (N2), and beer gas. Locally based in Santa Ana, we supply beverage gases to businesses of all types and sizes, from small cafes, restaurants, and bars to large entertainment and sports venues. Our clients include Angel Stadium, Honda Center, Subway, Flame Broiler, Corner Bakery, Black Angus, and Dodger Stadium. We offer high quality, beverage-grade gases, excellent customer service and competitive pricing.

We provide N2, CO2, and blended gas delivery. We understand that beverages play such an important role in a restaurant and we are responsive to your needs. We determine your gas needs and set you up on a regular delivery schedule. If necessary, due to beverage system issues, same-day gas delivery is available for an additional fee if requested before 2pm Monday through Saturday. For requests that come in after 2pm, we can provide next-day delivery.

If you use CO2, nitrogen, or blended gases for a kegerator or hydroponic gardening, Giant CO2 offers convenient and affordable tank refill services at our Santa Ana facility. We will fill gas tanks of any size as long as they are owned by the customer and have been DOT certified/hydro-tested within the last five years. If certification has expired, we can conduct on-site hydrostatic testing and re-certify your tank in about a week.

Giant CO2 is a family owned and operated local Orange County business. We pride ourselves on being knowledgeable, helpful, safe, and reliable. They've also received hazmat training for the safe handling of high-pressure cylinders.

Whether you need a one-time tank fill for your personal kegerator or a truck load of CO2 cylinders delivered to your site on a regular basis, Giant CO2 has you covered. Call today to learn more about our carbon dioxide, nitrogen, and beer gas delivery, cylinder replacement, and tank refill services for Orange County. Site surveys and estimates are free.
