Carbon Dioxide Filling Station

Product Overview

The CO₂ filling station is an industrial system specifically designed for the safe and efficient filling of liquid carbon dioxide. It enables precise filling of liquid CO₂ into various containers, including cylinders and storage tanks, meeting the diverse gas supply needs of industries such as food and beverage, fire protection, and welding.

The system stores liquid CO₂ in low-temperature, high-pressure storage tanks and integrates precision filling pumps, vaporizers, and weighing monitoring systems to ensure safe, stable, and high-accuracy filling operations.

Working Principle

The system utilizes the low-temperature, high-pressure state of liquid CO₂ stored in the tank. A filling pump transfers the liquid CO₂ into target containers. The pump can be either plunger-type or diaphragm-type, with flow rates ranging from several liters per minute to tens of liters per minute and pressures up to 10-20 MPa, ensuring smooth filling operations.

Liquid CO₂ can also be vaporized in a vaporizer to produce gaseous CO₂ for applications requiring gas supply. During the filling process, a weighing system continuously monitors the filling quantity to ensure accuracy and consistency.

All pipelines and valves are made of stainless steel, offering excellent corrosion resistance and sealing performance, ensuring safe operation under cryogenic and high-pressure conditions.
