Learn more about the different gases commonly used in the food freezing industry.
CO₂
Used in cryogenic freezing as dry ice or liquid CO2, freezing food at -78°C (-109°F), commonly used for meat, seafood, and baked goods.
N₂
Used to displace oxygen and create inert atmospheres in freezing tunnels to prevent oxidation and freezer burn.
O₂
Used in modified atmosphere packaging (MAP) of fresh frozen meat to maintain color and freshness.
NH₃
The most widely used refrigerant in large-scale industrial freezing and cold storage facilities due to its high efficiency and low cost.
CO
Occasionally used in modified atmosphere packaging (MAP) for meat products to maintain a bright red color, though its use is highly regulated due to safety concerns.
Ar
Occasionally used as a cryogenic freezing agent in specialized applications.
LN₂
The most widely used cryogenic freezing agent, capable of freezing food products extremely quickly at -196°C (-320°F), preserving texture, flavor, and nutritional value.

Liquid Nitrogen (LN2) is the most widely used cryogenic freezing agent, capable of freezing food products almost instantly at -196°C (-320°F). It is preferred for individual quick freezing (IQF) of fruits, vegetables, seafood, and meat because it preserves texture, flavor, and nutritional value better than conventional freezing methods.
Ammonia (NH3) is the most popular refrigerant in large-scale industrial freezing and cold storage facilities. It is highly efficient, cost-effective, and environmentally friendly compared to synthetic refrigerants, making it the refrigerant of choice for food manufacturers and cold storage operators.
Yes. We offer real-time monitoring for most of our gas applications to make sure you never run out. Our solution provides you (and us) with accurate updates on your levels so we can optimize your gas delivery, detect leaks and other issues – saving you money while supporting our sustainability commitments.
