Carbon Dioxide
CO₂
As an essential industrial and everyday gas, carbon dioxide (CO₂) plays a vital role across a wide range of applications. Messer operates multiple carbon dioxide (CO₂) production sites across China, supplying the gas in gaseous, liquid, and solid (dry ice) forms. With a portfolio ranging from industrial to food-grade purity levels, we offer flexible supply solutions tailored to diverse industry and process requirements. In the dry ice sector, Messer has established a reliable production and distribution system, ensuring consistent supply of blocks, pellets, and dry ice snow. We also operate three dedicated electronic specialty gas plants capable of producing electronic-grade CO₂. In the food industry, carbon dioxide plays a vital and irreplaceable role across key processes such as beverage carbonation, cold chain transport, food chilling and freezing, dry ice cooling, and modified atmosphere packaging (MAP)，all helping to ensure product quality and safe delivery. In agriculture, CO₂ acts as a gaseous fertilizer that boost photosynthesis in green house crops, improving yield and quality. In water treatment, CO₂ serves a neutralizing agent for pH control, providing a safer and more sustainable alternative to strong acids. In high-tech sectors, carbon dioxide plays a key role in various critical processes — such as wafer temperature control and process stabilization in semiconductor manufacturing, cooling and cleaning of components in electronics, and supercritical fluid extraction in life sciences and materials processing. In gas application for chemical and beverage industries, the cold energy released during the vaporization of liquid CO₂ can captured and reused, enhancing overall energy efficiency. At the same time, liquid CO₂ is rapidly gaining adoption as an eco-friendly refrigerant in batter electronic vehicles for heat pumps and battery cooling, offering a clean and efficient alternative to conventional refrigerants.

What Are Safety Hazards Associated When Working with CO₂
For most industrial applications, CO₂ is stored as liquid under a high pressure in cryogenic tanks. Liquid CO₂ is typically around 0°C, while solid CO₂ (dry ice) reaches temperatures as low as -78.5°C, posing a serious risk of cold burns. Make sure that proper protective equipment is worn when working around liquid CO₂ and dry ice.
Because CO₂ is heavier than air, it tends to accumulate near the ground, especially in low-lying areas. Facilities that use nitrogen in any form should always be equipped with exhaust ventilation systems and oxygen monitors.
CO₂ can displace oxygen, creating a risk of asphyxiation and potential respiratory hazards. If you suspect unsafe CO₂ buildup in a particular area, do not enter. Notify the appropriate safety personnel and keep other people away.
