Chart 2

All components utilized in the test are standard, off the shelf production items of Exactrix Global Systems
Precision and selected orifices with less than 1% port to port variance are available from Exactrix
Injection orifices should be checked every 500,000 gallons of NH3 applied
Testing reflects dual stage manifold operation in the secondary stage
