Scene One: Chain Bars, Cafés & Commercial Catering
Heavy steel CO₂ tanks are rust-prone and labor-intensive to replace, taking up storage space and causing unstable beverage carbonation. Mixed tank styles also bring difficulties to chain store asset management.
Midstar lightweight aluminum CO₂ canisters feature food-grade anti-corrosion inner coating and steady gas output. Easy for staff to carry, unified sizes simplify multi-branch inventory control, and custom branding supports standardized store fleet management.
Scene Two: Craft Breweries & Beverage Production Plants
Breweries need long-term stable CO₂ supply for carbonation. Steel tanks push up logistics costs, and inconsistent tank standards conflict with automated brewing lines.
Midstar aluminum CO₂ cylinders maintain constant pressure during production. Light design cuts factory transport costs, and universal valve interfaces fit most brewing equipment. Mass consistent supply meets large-scale factory deployment demands.
Scene Three: Beverage Equipment Wholesalers & Soda Machine OEM Brands
Equipment brands face high certification and inventory costs when sourcing supporting CO₂ tanks separately. Fragmented tank accessories also lead to frequent after-sales issues.
Midstar canisters hold complete ISO 7866 & DOT-3AL certifications. We support OEM customization on cylinder colors, logos and full valve sets. Global full-container bulk shipment lowers stocking pressure, helping brands complete full beverage machine product lines rapidly.

FAQs
Q: What happens during CO2 cylinder testing?
A: During the test, your CO2 tank will be checked for leaks, pressure sealing and structural integrity, which will help ensure that your CO2 tank is working properly. It is important to ensure that your CO2 tanks are inspected regularly as it can affect the quality of your homebrew.
Q: What pressure should I set for CO2 cylinders?
A: Most brewers agree that you should aim for a CO2 tank PSI of between 12 and 14. Our best advice is to confirm the optimal CO2 pressure with the company that sells you the refrigerated keg. If you notice that your beer is too foamy or too flat, this may indicate that your CO2 carboy is not set to the correct pressure. Correctly adjusting the keg compression will help make your beer perfect every time.
