Product Overview

MINGXIN’s LCO₂ (Liquid Carbon Dioxide) Filling Station is a highly integrated, specialized system engineered for the safe, precise, and rapid filling of LCO₂ into high-pressure cylinders, bulk tanks, and industrial process lines. By seamlessly combining advanced cryogenic storage, high-pressure pumping, precise weighing, and vaporization technologies, our turnkey filling station provides a highly reliable gas distribution solution tailored for the food and beverage, firefighting, welding, and broader industrial sectors.

Key Features & Design Highlights

  • High-Pressure Rapid Filling: Engineered with heavy-duty cryogenic pumps capable of delivering 15 to 30 MPa (150–300 Bar) of pressure, ensuring fast, continuous, and highly efficient cylinder charging.

  • Precision Control & Automation: Equipped with intelligent electronic weighing scales featuring an automatic shut-off function. This guarantees an exceptional filling accuracy of ±0.5 kg, preventing dangerous overfilling and eliminating product waste.

  • Superior Cryogenic Storage: Utilizes MINGXIN's premium high-vacuum insulated storage tanks (5 to 200 m³ capacity) that boast a remarkable daily evaporation rate of ≤0.1%, ensuring your bulk LCO₂ remains stable and loss-free.

  • Energy-Efficient Vaporization: Integrates high-performance ambient air or electric vaporizers capable of gasification capacities ranging from 50 to 5,000 Nm³/H, customized to meet your facility's exact flow requirements.

  • Modular, Skid-Mounted Design: Core components are pre-assembled, piped, and wired on a compact steel skid. This "Plug & Play" framework drastically reduces on-site installation time and optimizes your facility's physical footprint.

  • Uncompromising Safety Standards: Built with a multi-tiered safety architecture, including Emergency Shutdown (ESD) systems, automatic pressure relief valves, leak detection, and explosion-proof electrical components to protect both operators and equipment.

The Standard Process Flow

  1. Storage: Bulk LCO₂ is securely stored in vacuum-insulated cryogenic tanks at optimal sub-zero temperatures.

  2. Pressurization: Specialized cryogenic piston pumps extract the liquid and boost the pressure to the required 15–30 MPa.

  3. Vaporization (If required): Ambient or electric vaporizers efficiently convert the high-pressure liquid CO₂ into gas for specific pipeline applications.

  4. Precision Filling: Automated filling manifolds and smart weighing stations charge cylinders or process lines with absolute pressure and weight control.

  5. Safety Monitoring: Continuous overpressure protection systems monitor the entire cycle to guarantee operational safety.

Industry Applications

  • Food & Beverage Industry: Centralized bulk supply for beverage carbonation, flash freezing, food preservation, and packaging.

  • Firefighting & Safety: Rapid, high-pressure filling stations for CO₂ fire suppression systems and portable fire extinguishers.

  • Metal Fabrication & Welding: Supplying essential, high-purity shielding gas for continuous industrial welding operations.

  • Industrial & Construction: Providing critical LCO₂ for refrigeration systems, chemical processing, and eco-friendly concrete curing.
