Liquid Bulk Carbon Dioxide Storage Tanks

Featuring the Carbo-Mizer®, Carbo-Mite®, Carbo-Max® and Perma-Max™ CO2 Storage Systems. After developing a soft drink carbonation solution for the world's #1 restaurant chain, we continued to innovate and our passion led us into new markets. By integrating our CO2 and nitrogen technology, we've created a mixed gas system for brewers of all sizes, from the smallest brew pub to full-scale breweries.

Bulk CO2 Systems

Chart systems provide carbon dioxide across a diverse range of applications including:

  • Brewing
  • Food freezing
  • Concrete curing - CO2 reduces the curing time and cost of concrete pouring
  • Vaccine storage
  • Cannabis growing
  • pH control of swimming pools
  • Die cooling
  • Dry ice pellets for fire fighting
  • Stage productions

Our Carbo Series bulk CO2 cylinders are at the heart of the system. Constructed from high grade stainless steel, individual cylinder capacities range from 220 to 1000 lbs (100 to 454 kg).

There are two principal liquid CO2 delivery mechanisms. The Vertical Liquid CO2 Delivery unit (VLCD) is pallet based and ideal for new business start-ups, new installations, hot-shot deliveries and remote operations. For larger volume users Chart's best in class Orca™ MicroBulk delivery truck has been specially engineered for liquid CO2 cylinder filling.

Carbo Series Systems

Serving a variety of markets and usage requirements, Carbo Series bulk CO2 systems meet the unique demands of every customer. Carbo Series systems eliminate run-outs, allowing your accounts to focus on customer sales rather than operations.

  • Proprietary vacuum maintenance system ensures optimized long-term performance
  • Certified to meet NSF and EC 1935/2004 standards, supporting growing global food safety initiatives within the beverage industry
  • Instrument grade isolation valves, rated for a 10,000 cycle life
  • Telemetry ready, optional liquid level gauges
  • 300 psig (20.7 barg) MAWP

The Carbo-Mizer Bulk CO2 System is available in either 300, 450, 550, 750 lb models as an affordable alternative to high pressure cylinders. These systems offer flow rates that meet the demands of high volume customers such as: fast food, convenience stores, restaurants and bars.


The Carbo-Max Bulk CO2 System is available as either a 600, 750 or 1000 High Flow System to meet the demands of high volume customers such as: stadiums, brew pubs, cineplexes and microbreweries.


Fast fill MicroBulk storage system designed specifically for CO2 applications. Incorporates many standard features from the Perma-Cyl range for easy installation, fast start-up and extended hold times, even during periods of low volume or no gas use. In addition a fast fill feature increases the fill rate from a standard beverage truck by more than 3x versus our standard Perma-Cyl series.

Perfect Pour

Combining Chart bulk carbonation and liquid nitrogen systems eliminates high pressure cylinders and run-outs and provides the perfect pour for beer and soft drinks, from the smallest brew pub to stadiums.
