Co2 Re-fills / Hydrotesting

All cylinders Centennial Tap Beer Service ships are empty of any gas. However, if you are in Colorado give us a call to schedule your onsite CO2 refill.  We are able to fill cylinders from 20oz to 20lb for Co2 at your location.  If we are unable to fill onsite, we also do exchanges and we deliver.  If your order is less than $50.00 that we are delivering we do have a $15.00 delivery fee.

Centennial Tap Beer Service also fills Blended Beer gas, which is a mix of 75% Nitrogen / 25% Co2, and also 100% Nitrogen.   Nitrogen gas is a different fill process and we can't fill onsite.  We offer exchanges on this gas and we deliver or you can come to our location in Hudson with an appointment.  Any cylinder larger than a 10# cylinder would need a dip tube inserted to be filled with the blend gas. Blend gas is necessary to pour Guinness or any stout beer. It is also necessary in a draft beer installation that is over 20 feet from the keg to the faucet.

Our hours to have your gas tanks filled or exchanged are:
Monday - Friday 9:00 am - 7:00 pm 

Our pricing for refills is:

All Co2 tanks need to be hydro-tested every 5 years. This is performed by DOT qualified re-test stations which we are. The purpose of the hydro-test is to make sure the tank is still in good working condition. That there are no cracks in the neck, excessive pitting, rust and that they are pressure tested to verify they can be used safely for a compressed gas. If you exchange your Co2 tank you should look at the date of the tank you are receiving in exchange and confirm it is still in date and not ready to expire. Test dates will be stamped in the shoulder of the cylinder. If the cylinder is old, you need to find the most recent date. The marking is identified with the month and year it was tested and also the re-test station ID number.

Our price to test a cylinder is $29.60.
