Ammonium Hydroxide (Aqua Ammonia) Systems

⮞ Standard commercial strength is 26-Degree Baumé, equivalent to 29.4% ammonia by weight.

⮞ Custom blends can be prepared to meet specific project requirements.

⮞ Baumé readings are standardized at 60° F to account for temperature variation.

⮞ Density: 0.8974 lbs per cubic foot (compared to water)

⮞ Freezing Point: Approximately -112° F for 26-Degree Baumé solution

⮞ Corrosive To: Copper, copper alloys, aluminum alloys, and galvanized surfaces

⮞ Vapor Pressure: Varies with temperature; at ambient conditions, 26-Degree Baumé solution is near atmospheric pressure

⮞ Excellent acid neutralizer; pH varies with concentration:

• 1%: 11.7 | 5%: 12.2 | 10%: 12.4 | 30%: 13.5

⮞ Used in SCR and SNCR systems to reduce NOx emissions

⮞ Preferred over anhydrous ammonia in applications requiring lower regulatory thresholds

⮞ Shipped and stored in non-pressurized containers

⮞ Should be stored in a closed, cool environment to prevent ammonia gas release and strength reduction

⮞ Complies with industry safety and regulatory standards
