High Pressure Cylinders & Auto-Changeovers

 CARBON DIOXIDE -  CO2 is the key to delivering the fizz to water, sodas, and beer. Southern fills cylinders of all sizes for carbonating everything from a home kegerator to a full bar tap. 


NITROGEN – Nitrogen is essentially an inert gas, and is used in cold brew coffee, tea and wine on tap. It is also preferred for product blanketing, pressure transfer, and bottle purging. 


NITROGEN BLEND – Nitrogen combined with CO2 it is used for "Heavy" beers - as in ales and stouts as well as "Nitro" coffees. The nitrogen imparts a creamier taste to both ales and coffee. We carry pre-blended cylinders for convenience but custom blends can be attained with CO2 and Nitrogen with the combination of a mixer. 


AUTO-CHANGEOVERS - Southern Oxygen & Welding Supply offers automatic cylinder switching units that work with any beverage gas cylinder up to 3000 psi. The auto-changeover provides a seamless hands-free switch between cylinders. The unit works with existing beverage gas regulators and requires no maintenance.
