Overview

Anhydrous ammonia is a colorless gas with a sharp, pungent odor, supplied as a liquid under pressure. It is an efficient refrigerant for large cooling systems and is widely used for emission control, metal heat treatment and chemical processing.

Key Characteristics

• Colorless gas with a sharp, pungent odor
• Toxic and corrosive, so it requires trained handling
• Lighter than air
• Highly efficient refrigerant (R-717)

Common Applications

• Industrial refrigeration and cold storage systems
• NOx reduction (SCR) in boilers, engines and power plants
• Nitriding and metal heat treatment
• Water treatment and chemical manufacturing
