Carbon Dioxide (CO₂)
Carbon dioxide is a colourless, odourless, non flammable gas that is formed by the burning of hydrocarbon with air, by the fermentation of liquids and as a by-product from chemical processes. It doesn’t sustain life and freezes at -78.5°C to form dry ice.
Supply
All cylinders are equipped with a valve for gas and liquid withdrawal. UNITED INDUSRIAL GASES FACTORY LLC supply bulk liquid CO₂ to the food and beverage industry.
Be safe
-
Keep CO₂ container tightly closed.
- Keep CO₂ container in a well ventilated place.
