Description

Carbon Dioxide CAS NO 124-38-9 is a colorless, odorless, non-flammable gas essential for a vast range of industrial and commercial processes. Its unique properties as a refrigerant, inerting agent, and carbonation source make it a critical raw material across multiple sectors. Key industries that rely on a consistent, high-quality supply include food and beverage processing, water treatment, metal fabrication, and pharmaceuticals.

Application

• Food & Beverage Industry: Used for carbonation of soft drinks and beers, as a cryogenic agent in food freezing and chilling (e.g., for meats and vegetables), and in modified atmosphere packaging (MAP) to extend shelf life.
• Water Treatment: Employed for pH control and re-carbonation in municipal and industrial water treatment facilities to stabilize water and prevent corrosion in distribution systems.
• Welding & Metal Fabrication: Serves as a shielding gas in MIG (Metal Inert Gas) welding to protect the weld pool from atmospheric contamination, ensuring clean, strong welds.
• Chemical Manufacturing: Acts as a raw material in the synthesis of urea, methanol, and various carbonates, and as a supercritical fluid for extraction and cleaning processes.
• Pharmaceuticals & Healthcare: Utilized in critical applications such as insufflation during minimally invasive surgeries (laparoscopy) and as a component in respiratory stimulants.
• Fire Suppression: A key agent in fire extinguishing systems, particularly for electrical and flammable liquid fires, where it displaces oxygen to suppress flames.
• Electronics: Used in its supercritical state for precision cleaning of wafers and components, removing photoresists and particles without leaving residues.
• Greenhouse Enrichment: Injected into greenhouse atmospheres to enhance plant growth rates and yields through accelerated photosynthesis.

Quality Control

Our Carbon Dioxide is produced and handled under stringent quality management systems to meet the exacting requirements of diverse industrial applications. We supply various grades, including Food Grade (meeting FCC and EIGA standards), Industrial Grade, and High-Purity grades for technical applications. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters to ensure compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store cylinders in a well-ventilated, secure, upright position in a cool, dry area away from direct sunlight, heat sources, and incompatible materials. Cylinder temperature should not exceed 50°C (122°F). Ensure storage areas are clearly labeled and comply with local regulations for compressed gases.
