  • NH3 Precision Anhydrous Ammonia Application for Systems

    Jan 27, 2015 · Anhydrous ammonia is stored and transported as a liquid. To maintain NH3 as a liquid it must be kept below –28°F or maintained under pressure. If the temperature of the NH3 increases above –28°F some of the liquid changes to a gas as the NH3 begins to boil. Application equipment typically uses tank pressure to deliver NH3 to the soil.
