Giant CO2 excels in providing restaurants, bars, sports venues, and corporate offices across Orange County and select areas of Los Angeles and Inland Empire with the highest quality beverage gas services available. We offer carbon dioxide (CO2), nitrogen (N2), and blended/beer gas for commercial, residential, and industrial use in a wide range of tank sizes for ongoing and one-time deliveries. These beverage-grade gases can be used in soda dispensers, nitrogenous beers, homebrewing kits, hydroponic gardening, cleaning/dusting, and more. Whether you need one tank refilled or hundreds of tanks replaced, we are sure to have a solution to meet your needs at a very competitive price.

At Giant CO2, we work hard to distinguish ourselves from other local companies that deliver CO2, nitrogen, and beer/blended gas by providing exceptional service. We've carefully selected trustworthy, professional staff and gone the extra mile to educate them thoroughly. Our drivers have on average at least three years of experience each and receive ongoing training on how to safely and efficiently transport and replace compressed air cylinders. They drive well-maintained trucks that are routinely reviewed by the California Highway Patrol Safety Division, and ensure every tank is properly connected to your beverage system or beer draught. Additionally, our drivers have the ability to identify when there is a problem, such as a leak or a bad regulator.

For our customers in our Orange County, Los Angeles, and Inland Empire service area, our gases are delivered on a weekly, biweekly, four-week, or as-needed basis. Additionally, clients who have completed all paperwork and are on an ongoing contract can receive same-day delivery -- a service that few competitors are able to accommodate. Same-day beverage gas delivery must be requested early in the day (usually before 2pm) and requires an additional fee. This service is particularly important for restaurants since the sale of fountain drinks offers such a high profit margin.

For residential customers who have their own gas tanks, we offer affordable and convenient CO2, nitrogen, or blended gas tank refill services as well as hydrostatic testing and tank requalification at our Santa Ana office. Walk-in tank refill is available Monday through Friday, from 9am to 4pm.

Call or visit family-owned and operated Giant CO2 today to learn more. As a testament to the quality of our services, our expertise, unrivaled customer service, and competitive rates, we have thousands of satisfied clients throughout Orange, Los Angeles, Riverside, and San Bernardino counties. Moreover, we receive nearly 99% of our business from repeat customers and through positive word of mouth. To get started with ongoing beverage gas delivery services, call and request a free on-site survey. During this survey, we'll determine what your expected usage will be, what size tanks you'll need, how to make the best delivery, and where back-up emergency tanks--if any--should be stored. We'll also review best practices for handling, storing, securing, and hooking up your tanks.

Nitrogen Gas Supplier, Orange County: N2 Tank Replacement & Delivery for Cities throughout Orange County & Select Parts of Los Angeles and Inland Empire


Locally based Giant CO2 is proud to be one of Orange County's preferred nitrogen gas supplier. We've been providing our premium-quality nitrogen gas to residential and commercial customers since 1990 and have thousands of satisfied clients. Over the years, our clients have chosen to stay loyal to us and refer us to their friends because we offer the best value in nitrogen gas: NF Grade nitrogen gas at competitive prices with unrivaled customer service. This gas is used to give stout beers their distinctive thick head, push nitrogenated beers through a tap on a keg, prevent oxidation when pushing juices, and even help serve cold brew coffees.

Beer Gas Supplier/Tank Replacement & Delivery in Orange County and Select Areas of Los Angeles and Inland Empire


As a full-service beverage gas supplier, Giant CO2 has also provided thousands of Orange County commercial and residential customers with high-quality beer gas. Beer gas is a blended gas that consists of a mixture of nitrogen and CO2 gas. Beer gas is typically used to push beer out of a keg, and is custom mixed according to whatever the beer manufacturer recommends (e.g. 50/50, 60/40, 75/25). For Guinness, for example, we are certified to produce their specific blend of CO2 and nitrogen to within 2% of their target ratio. By controlling their blended gas, Guinness has become known for a very special pouring and tasting experience. Call today to learn more; we can deliver our beer gas anywhere in Orange County and select areas of Los Angeles, Riverside, and San Bernardino. We also refill small, privately-owned cylinders at our centrally located facility in Santa Ana.

Walk-In Beer Gas, Nitrogen Gas, & CO2 Tank/Cylinder Refills:


Ideal for Home Brewers/Residential Clients in Santa Ana, Tustin, Orange, Newport Beach, Huntington Beach, Mission Viejo, Costa Mesa, Anaheim, & Irvine

Giant CO2 makes it easy and affordable for those in Orange County who wish to fill or refill a small, 5- to 20-pound CO2 tank or cylinder for their soda system kegerator or hydroponic system. Between the hours of 9am and 4pm, Monday through Friday, customers are welcome to walk into our office with their unbranded, new or used tanks. Our office is located at 531 Goetz Avenue in Santa Ana, California. Most CO2 tank refills take just a few minutes, but can take as long as 30 minutes if you request a custom beer gas, which allows time for putting your filled container on a special rolling table to be thoroughly blended.

CO2 Gas Cylinder Testing: Hydrostatic Testing & Tank Recertification


The Department of Transportation (DOT) requires all compressed gas cylinders to be recertified every five years. Without proper certification, a cylinder cannot be refilled. To determine if your CO2 tank needs to be recertified, check the date stamped near its neck. If the date falls outside of the last five years, you'll need to have the cylinder hydrostatic tested (aka hydro-tested) by a DOT-approved facility.

At Giant CO2, we are proud to offer tank recertification services through our affiliated subdivision, Orange County Cylinder Requalification (OCCR). OCCR is DOT approved. Residential customers must bring their tanks in to our Santa Ana facility, but we can arrange tank pickup and dropoff for commercial and industrial customers who meet our minimum requirement. Recertification takes about a week, and includes a new date stamp. We can also fill the tank with the gas of your choice before we return it to you. Call today to learn more.
