Liquid carbon dioxide (CO₂) is carbon dioxide stored at low temperature and moderate pressure, allowing a large volume of gas to be kept in compact liquid form. To maintain CO₂ in liquid state, it must be stored in a specialised cryogenic tank that provides temperature stability and pressure control.
Liquid CO₂ storage tanks ensure uninterrupted gas supply for food and beverage processing, refrigeration, welding, manufacturing and environmental applications. Instead of handling multiple cylinders, industries use bulk storage tanks for efficiency, safety, and lower long-term cost.
What Is a Liquid CO₂ Storage Tank?
Liquid CO₂ storage tanks are pressure vessels designed to store carbon dioxide in liquid state at low temperature (-18°C or below) and controlled pressure.
The tank delivers gas on demand through a vapourisation system, keeping use continuous and stable.
Liquid CO₂ Tank Features
Our liquid CO₂ tanks are engineered to deliver maximum efficiency, low evaporation loss, and safe operation.
- Vacuum-insulated double-wall construction: Minimises heat ingress and reduces CO₂ loss through boil-off.
- Stable temperature & pressure control: Maintains cryogenic storage temperature and regulated working pressure.
- Integrated safety & control instrumentation: Equipped with pressure relief valves, level gauges, and optional remote monitoring.
- Continuous gas supply: Liquid CO₂ is vaporised into gas on demand for uninterrupted supply to the user.
Tank Specifications (Common Selections)
| Model (m³) | Working Pressure | Orientation | Purity Options |
|---|---|---|---|
| 5–30 m³ | 16–22 bar | Vertical | Industrial / Beverage / Food |
| 30–200 m³ | 16–22 bar | Vertical / Horizontal | Industrial / Beverage / Food |
Custom sizes available. We design according to ASME, CE, ISO, or local regulatory requirements.
How the Tank Works
- CO₂ is stored as liquid at low temperature and high pressure.
- When gas supply is required, the liquid CO₂ flows through a vaporizer.
- The vaporizer converts liquid CO₂ into gas.
- A pressure control system ensures safe and stable delivery.
- This allows continuous gas supply without cylinders or frequent refilling.
Application of CO2 Bulk Storage Tank
Beverage Industry and Home Brewing:
CO2 is widely used in the beverage industry to create carbonated drinks and soda water.
It also plays a crucial role in pressurizing beer draft systems.
Whether on an industrial scale or for home brewing enthusiasts, CO2 tanks are essential for producing our favourite fizzy beverages.
Special Effects:
CO2 tanks are commonly employed in entertainment venues, including tours, events, theme parks, nightclubs, and bars.
They are used to simulate steam and smoke, creating impressive atmospheres that enhance performances, movie sets, and events.
From enhancing a DJ’s show to adding magic to a gathering, CO2-based special effects are visually captivating and safe.
Carbon Capture Technology:
Carbon dioxide storage tanks play a crucial role in carbon capture technology.
This technology aims to reduce greenhouse gas emissions by capturing and storing CO2, thereby mitigating its atmospheric concentration.
Doing so contributes to lowering the risk of rising global temperatures.
Oil and Gas Industries:
CO2 bulk storage tanks are used in the oil and gas sector.
They help control oil well pressure and can be utilized to extract impurities from oil3.
Industrial Production:
Large liquid carbon dioxide storage tanks meet the needs of industrial production.
These tanks provide a reliable supply of CO2 for various processes and applications.
