Co2 booster is a multiphase carbon dioxide pump, which is able to process both carbon dioxide gas and gas-liquid carbon dioxide mixture. That is, multiphase carbon dioxide booster pump can suction low-pressure carbon dioxide, whether in gaseous, vaporous or gas-liquid mixed state, and then discharge high-pressure liquid Co2 through pressurizing carbon dioxide. Therefore, carbon dioxide booster can ensure carbon dioxide always remaining in liquid state during pumping or filling carbon dioxide process. In order to facilitate you to process carbon dioxide of diverse phases, we provide Liquid Co2 boosters and Multiphase Co2 boosters for you to choose from.


Carbon dioxide critical pressure is 7.39MPa. Co2 booster pump utilizes pressurizing carbon dioxide to transfer or fill carbon dioxide. It can suction both liquid CO₂ and multiphase CO₂, then pressurize carbon dioxide to above 7.39MPa, thereby discharging liquid carbon dioxide. Co2 booster uses compressed air as driving power, and its discharge pressure is directly proportional to drive air pressure. So you only need to add an air regulator and a pressure gauge, then you can easily set or adjust carbon dioxide booster discharge pressure by reading the pressure gauge while adjusting the air regulator.





In order to facilitate your operation, we built the carbon dioxide booster system. It integrates Co2 booster pump and control kit into a robust skid, thus easy to move and operate. And it is suitable to act as a Co2 injection system, Co2 transcritical system or Co2 compressor.

Based on carbon dioxide boosters, we created Co2 refill machines to facilitate you filling Co2 into diverse cylinders. Automatic Co2 filling machine comes with automatic weighing function to avoid overfilling Co2. And manual Co2 filling machine is suitable for users with limited budgets.
CO₂ critical temperature is 31.06°C and critical pressure is 7.39MPa. If you use carbon dioxide booster to pressurize CO₂ to above 7.39MPa at a temperature below 31.06°C, you will obtain liquid CO₂. And if you want to get high-pressure CO₂ gas, that is, you don’t want CO₂ liquefaction, you need to control CO₂ temperature above 31.06°C.
If your carbon dioxide is pure liquid which usually comes from dewar tank or cryogenic tank, Liquid carbon dioxide booster is suitable for you. But if your carbon dioxide is pure gas or gas-liquid mixture which usually comes from steel cylinder, multiphase carbon dioxide is more suitable for you. Please contact us for help If you don’t know how to select.
Yes. Our carbon dioxide booster uses oil-free compression to ensure you obtaining high purity CO₂ and food-grade CO₂.
Carbon dioxide is a high-pressure liquid gas that is usually stored in cryogenic tanks or steel cylinders in liquid form. During transfer or filling Co2 process, carbon dioxide is prone to undergo gas-liquid phase transition at room temperature. That is, liquid carbon dioxide is vaporized thus converting into carbon dioxide gas or gas-liquid mixture. So you need to use carbon dioxide booster to pressurize carbon dioxide to ensure the carbon dioxide always remaining in liquid phase.
