A Reliable Supply of Gas and Liquid Carbon Dioxide (CO₂) for Food, Beverage, and Industrial Applications

CO₂ enables rapid freezing compared to other mechanical methods for protein, baked goods, prepared meals, and other perishable foods, helping to preserve texture, taste, and shelf life. Our team works with you to help decide which freezing solution you need based on your current and future production goals.

Precise temperature control during mixing is critical for producing sausages, hamburger patties, chicken nuggets, and other formed protein products. Bottom‑Injection delivers liquid CO₂ at the bottom of the mixer, removing heat faster and more uniformly than top‑down methods.

Messer works with your team to evaluate your mixer, batch size, and temperature targets, then designs bottom‑injection solutions that improves yield, appearance, and throughput that retrofits to your existing mixer.

CO₂ snow, pellets, and dry ice provide flexible, fast, and moisture‑free chilling for food processors that need temperature control outside of mixers, freezers, or ingredient pre‑conditioning. These formats are commonly used for spot chilling, box or combo bin chilling, surface temperature reduction, packaging support, and short‑term cold‑chain control for meat, poultry, seafood, produce, and prepared foods.

Messer works with your team to determine whether CO₂ snow, pellets, or dry ice best fits your process needs.

Chilling flour and other dry ingredients with liquid CO₂ helps food manufacturers maintain precise temperature control, protect product quality, and improve downstream processing consistency.

Liquid CO₂ provides rapid, moisture‑free cooling through bottom injection, inline cooling, or CO₂ snow application, pulling heat out quickly without affecting ingredient functionality or adding water.

CO₂ for stunning is used in poultry and livestock operations to humanely render animals unconscious. In addition to routine processing, CAS systems play a critical role during emergency depopulation events, such as avian influenza outbreaks to protect animal health, worker safety, and the surrounding food supply.

Messer works closely with producers, integrators, and emergency response teams to design safe, reliable CO₂ supply and delivery solutions for CAS applications that comply with animal welfare and biosecurity requirements in high‑stress, time‑critical situations.

Messer supplies high-purity beverage-grade CO₂ for carbonation in soft drinks, beer, and sparkling waters. Beverage producers rely on consistent CO₂ purity to maintain product taste, aroma, and shelf life. CO₂ also plays a key role in packaging and dispensing systems to protect beverage integrity from filler to final seal.

Our award-winning team continues is recognized by some of the world's leading beverage brands for offering:

• Tailored application solutions to protect product quality.

• Quick service response during demand challenges.

• Turnkey beverage gas installation.

CO₂ is used in applications like late-stage inerting during urea synthesis for fertilizer production, making it a key feedstock for agricultural chemical manufacturing. We collaborate with your plant operators to understand throughput, purity, and production cycles, helping design a dependable storage and delivery CO₂ solution.

CO₂ is a key input for steps like cryogenic snow cleaning of parts, gas-assist injection molding, spot mold cooling, foaming, and cryogenic grinding of thermoplastics and elastomers. These applications increase throughput, improve part quality, and reduce residue and waste.

CO₂ is used in chlor-alkali production to enhance brine treatment, improving purity, reducing chemical consumption, and supporting more efficient downstream processing. Messer works closely with chlor‑alkali operators to understand brine composition, membrane sensitivity, and operational constraints, delivering precision CO₂ injection strategies that improve efficiency and reduce chemical consumption.

Supercritical carbon dioxide (scCO₂) is a powerful, tunable solvent used across the chemical industry for high‑selectivity extraction, purification, and fractionation. When CO₂ is brought above its critical temperature and pressure, it exhibits both gas‑like diffusivity and liquid‑like solvency, allowing it to efficiently extract target compounds without leaving solvent residues.

Ultra‑High Purity (UHP) CO₂ is used in semiconductor manufacturing for advanced wafer cleaning, photolithography process control, and other contamination‑sensitive, tool‑level applications where gas purity is critical. High‑purity CO₂ is also used in analytical and testing environments as a calibration, reference, or test gas, supporting precise gas analysis and process monitoring in electronics and specialty manufacturing.

Messer supports contamination sensitive environments with dependable UHP CO₂ supply, consistent quality monitoring, and the knowledge and experience that helps protect your yield and tool uptime.

CO₂ is widely used as a shielding gas in Gas Metal Arc Welding (GMAW), particularly when welding steel. As a reactive gas, CO₂ provides deep weld penetration, making it ideal for heavier sections and structural applications.

Our team works with you to find the right blend for your needs.

CO₂ snow cleaning is an environmentally friendly, non‑abrasive, residue‑free cleaning method used across the manufacturing industry. Because of the precision it offers, CO₂ snow cleaning is ideal for molded plastics, metals, electronics, optical components, and painted/coated surfaces.

Messer’s team of experts can help you determine the right uses and methods for your specific process needs.

CO₂ is used for pH control, inerting, and safety‑related applications in mineral extraction and processing environments.

CO₂ EOR increases oil mobility by reducing viscosity and swelling the oil, improving flow to the wellbore and lifting recovery in mature or partially depleted reservoirs. Huff‑n‑Puff allows dissolved CO₂ to mobilize residual oil before flowback and recycling of gas.

CO₂ is a critical component in energized and foamed fracturing systems used to reduce water intensity, improve cleanup, and enhance stimulation performance in water‑sensitive, depleted, or unconventional reservoirs.

As a trusted bulk CO₂ supplier, we support frac operations with high‑volume CO₂ supply for foam frac, energized pre‑pad, and hybrid CO₂/N₂ systems. Our team understands gas quality requirements, pumping schedules, and logistics at the wellsite, and works with you to ensure consistent delivery that keeps crews pumping and minimizes non‑productive time.

USP CO₂ meets strict quality benchmarks for pharmaceutical ingredients and is used in cell culture incubation and in inerting, purging, and blanketing steps to safeguard product quality during pharmaceutical production. Messer’s team partners with your process engineers to understand your cleanroom environment, bioreactor requirements, contamination risks, and regulatory constraints, then develops CO₂ supply and distribution solutions that meet your process needs.

CO₂ is widely used in pulp and paper mills for pH stabilization and pulp washing, offering a precise, controllable alternative to strong mineral acids.

Messer works closely with your operations team to understand process conditions, target pH ranges, and system constraints, then designs a CO₂ supply and injection solution that integrates into existing washing and pH control systems. Our team helps mills optimize brown-stock washing or alkaline bleaching stages, by reducing maintenance burden, lowering water consumption, increasing capacity, and decreasing chemical use and wastewater chemical oxygen demand (COD).
