​At Giant CO2, we provide CO2 (Carbon Dioxide, Beverage Grade) & N2 (Nitrogen) and blended gas (CO2/N2) walk in tank refills while you wait, as long as your tank is in hydro-test date and is personally owned. If the date of the last hydro-test is within the past five years, we can fill it and return it to you. If the tank is out of hydro-test date and needs hydro-testing, we provide hydro-test service at $39 per tank. Hydro-test service takes 1-2 weeks. You will need to leave your tank with us for this service. If your tank passes the testing, we'll requalify and re-stamp it, certifying it for another five years. Once it has been requalified, it is ready to be filled.

 

For those who want beer gas, you can drop off your tank and pick it up within 24-48 hours. The beer gas takes additional time to process for the gas to become fully blended. 

​

At this time, we can fill up to 3 tanks per customer at one time on a walk-in while you wait basis. If you have more than 3 tanks to fill, please talk with us about how we can provide that additional service. 

 

​Our kegerator CO2 & N2 refill station at 531 Goetz Avenue in Santa Ana, California, is located between the 405, 55, and 5 freeways.
