How to Detect nh3 Liquefaction reclaimer for transformers

In evaluating the hazardous potential of a particular liquid, the flash point is gener-ally considered the most important criterion to consider. However other factors, ignition temperature, explosive range, vapor density and rate of evaporation, have a bearing on the liquid's hazardous potential. For example, the concentrations of a

  • 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.

    For example, if your transformer tested 0.1%, you need to go to 0.3% by adding 0.2% of the total weight of the transformer oil. The nameplate gives the weight of oil—say 5,000 pounds—so 5,000 pounds X 0.002 = 10 pounds of DBPC needs to be added. It’s ok if you get a little too much DBPC; this does not hurt the oil.
