What is Ammonia?
Ammonia (NH3) is a pungent, colorless gas approximately 40% lighter than air. Pure ammonia (also known as anhydrous ammonia) boils at -28ºF. Ammonia is a gas at atmospheric temperature and pressure. It must be under pressure to maintain a liquid state.Purchase High-quality Ammonia of Various Purity Grades
We offer anhydrous ammonia and aqua ammonia for applications such as:
• Industrial refrigeration
• Water treatment
• Heat treatment
• Diesel exhaust fluid (DEF)
• Chemical processing
For your tanks or systems, we perform pump-outs to help ensure the purity vital to your ammonia based processes. Our offering of periodic, scheduled maintenance can minimize the need for costly repairs and reduce the risk of ammonia release. These services are performed by our technicians at Airgas Specialty Products, who follow the latest in PSM/RMP/OSHA safety guidelines. Through them, Airgas can provide on-site ammonia equipment maintenance faster and more cost-effectively than internal staff.
Food, Beverage & Retail
Ammonia is used as an efficient and eco-friendly industrial refrigerant. Airgas prevents costly ammonia contamination from impacting client system efficiency, while supplying customers through a nationwide fleet of delivery trucks. We offer anhydrous ammonia safety training and ammonia services such as system pump-outs or distillation, which removes contaminants without shutdown.
Government & Municipalities
Chloramine (made by combining ammonia with chlorine) is used as a safer, more efficient and stable alternative to chlorine in water treatment. Chloramines do not form the EPA regulated carcinogen THM (trihalomethanes), and are known to improve the taste and odor of drinking water. Airgas provides NSF-certified products for the treatment of drinking water.
Metal Fabrication & Manufacturing
Disassociated ammonia is used to form atmospheres for metal heat-treating processes such as nitriding and annealing.
Energy & Chemical; Primary Materials
Power, waste and industrial plants use ammonia via total DeNOx applications to lower their emission of mono-nitrogen oxides per EPA standards. Airgas supplies ammonia, ammonia equipment and expertise, offering more support than any other supplier. As the industry leader in ammonia technology, safety, regulatory issues and supply reliability, we’re the only supplier offering SCR grade aqua ammonia nationwide. In addition to hands-on safety training, we help customers with OSHA and EPA-mandated programs such as Risk Management Plans and Process Safety Management.
Fleet-Based Commercial Services
Ammonia is used as a component in Airgas diesel exhaust fluid (DEF) which reduces the amount of nitrogen oxide (NOx) released via diesel exhaust systems. Our DEF solutions keep the Selective Catalytic Reduction (SCR) technologies in diesel vehicles performing at optimal levels. We help customers find the best storage and delivery modes while offering safety, equipment and application support.
Ammonia has diverse uses in chemical processing, from a leavening agent and acidity regulator in food manufacturing to caramel coloring in food and beverage production.
High-pressure & Liquid Cylinders/Dewars
Airgas continually meets supply needs with compressed ammonia gas and ammonia liquid cylinders.
When customers have outgrown cylinders, Airgas MicroBulk Services offer gas supply solutions that save time and storage space. Airgas MicroBulk Services can help customers save money by lowering gas use and gas waste.
We keep our customers in constant supply with a distribution infrastructure that features 16 air-separation units, more than 60 bulk-gas specialists and more than 14,500 bulk tanks.
