Anhydrous Ammonia in Bulk

Anhydrous ammonia is the most efficient industrial refrigerant available and a base chemical for a large part of the nitrogen industry. It carries more latent heat per kilogram than any synthetic refrigerant and has zero ozone depletion potential, which is why large cold stores and food plants still build around it. It is acutely hazardous and is supplied only to buyers with the necessary licences and engineered systems.

• Packing: cylinders and bulk road tankers, returnable

Applications

Refrigeration grade carries tighter water and oil limits than general industrial grade, so state your application when enquiring.

• Industrial refrigeration in cold stores and food processing
• Reducing agent in SCR and SNCR NOx control
• Feedstock for nitric acid, urea and nitrogen chemicals
• Nitriding and heat treatment atmospheres in metallurgy
• pH control and neutralisation in industrial processes

Safety, Handling and Compliance

Ammonia is acutely toxic by inhalation, causes severe cold burns as a liquid, and is flammable within a defined range. It is a scheduled hazardous substance.

• Valid PESO licence and statutory approvals required before supply
• Gas detection, water deluge and emergency kit mandatory on site
• Trained personnel and SCBA must be available at all times
• Never use copper, brass or zinc anywhere in the system
• SDS and emergency response guidance issued with every consignment

Ordering

Enquiries must include your licence details and storage arrangements. Eligibility is confirmed before we quote.

• Supplied to licensed industrial buyers only
• Minimum order quantity 100 kg
• GST tax invoice and batch Certificate of Analysis on every order
• Transport by approved hazardous goods carrier with TREM card
• Empty containers returnable against deposit

FAQs

Questions buyers commonly ask about anhydrous ammonia.

• Do I need a licence? Yes, statutory approvals and PESO licensing are required before supply.
• Why is ammonia still used as a refrigerant? Highest latent heat per kg, low cost and zero ozone depletion potential.
• Why avoid copper in the system? Ammonia attacks copper and its alloys and will cause leaks.
• Are containers returnable? Yes, on a deposit basis.
• What documents are provided? GST invoice, batch CoA, SDS and TREM card.
