Carbon Dioxide Liquefaction Machine

Product Overview

The CO₂ low-temperature liquefaction system compresses CO₂ gas from atmospheric pressure to approximately 2 MPa and then liquefies it by absorbing its latent heat through a refrigeration unit.

The system efficiently produces industrial-grade or food-grade liquid CO₂, widely used in foam material production lines, as well as various industrial and food processing applications.

Working Principle

CO₂ gas is pressurized to around 2 MPa and cooled in a refrigeration cycle, which absorbs the gas’s latent heat and quickly converts it into liquid.

The combination of precise pressure control and efficient refrigeration ensures stable production of liquid CO₂ while meeting different purity requirements, making it suitable for both industrial and food processing operations.

Key Features

• High Liquefaction Efficiency: Rapidly converts CO₂ gas into liquid through pressurization and cooling, supporting large-scale production.
• Wide Applicability: Produces both industrial-grade and food-grade liquid CO₂ to meet diverse market and process requirements.
• Flexible Application: Suitable for foam materials, beverages, food processing, and other industries.
• Reliable Performance: Offers excellent liquefaction efficiency and operational stability for long-term use.

Applications

• Beverage Industry: Production of carbonated drinks and gas injection processes.
• Food Processing: Use of food-grade liquid CO₂ for freezing, preservation, and other processing operations.
• Metallurgy: Gas protection in metallurgical processes.
• Chemical Industry: Acts as a reaction medium or raw material in chemical processes.
