N-Ject® NH3

Simple. Accurate. Reliable.

CapstanAG's N-Ject NH3 system provides row-to-row uniformity with built-in sectional control and variable rate capability.

N-Ject utilizes PWM technology within the modular manifold to control anhydrous ammonia flow to each row. 

N-Ject tailors the pulse duty cycle as it quickly compensates for changes in rate or speed to maintain your target application.

Correct application of anhydrous ammonia is critical to getting the best yield from your crops.


  • Distribution, cooling and metering all in one

  • Consistent application per row

  • Modular setup to match toolbar needs

  • Greatly eliminates distribution variability


  • Precise row to row accuracy

  • Compensates for rate and speed changes

  • Instantaneous variable rate

  • System status updates on demand

N-Ject NH3 has less than 6% distribution variability, providing an on-target application.  Conventional application technology typically performs at 18-22%.  This high level of distribution variability often leads to unwanted streaks and entire fields misapplied.


System Link - PinPoint II

The N-Ject manifold coupled to the hardware and display unit of PinPoint II gives you the following benefits and enhanced features:

  • Individual Row Control

  • Boundary Mapping

  • Turn Compensation

  • Valve/System Diagnostics


Anhydrous Ammonia Sentry

See the most out of your application with N-Vision.  With easy installation, your anhydrous season gains efficiency and effectiveness with no added effort.

N-Vision removes naturally occuring vapor from the tank and plumbing to provide liquid state ammonia to the metering device. 

N-Vision shows the operator real-time demand and capacity based on application conditions, field terrain, and tank performance capacities.  This results in a consistent application throughout the entire tank.

Pure, clean liquid and real-time application diagnostics redefines your anhydrous success.


  • Immediately identify flow restrictions

  • Pull supply tanks dry with confidence

  • Tank feed diagnostics result in 15% more usable product per tank

  • Filters are designed for greatly extended acres before servicing

  • Know exactly when to speed-up or slow-down based on supply


  • Tank feed diagnostics
    Real time system feedback

  • Passive refrigeration
    Removes unwanted vapor

  • 3D depth filtration
    Multi-layered particle barrier

How it Works

(1)  Inlet(s) - Liquid, vapor, tank additives and contaminates enter the housing inlet(s) from the supply tank and plumbing.


(2)  Filtration - NH3 passes through the 3D membrane, catching all contaminates, protecting your downstream investment.


(3)    Separation - The vapor rises to the vapor head while a measured accumulation of liquid supplies the outlet ports.


(4)    Vapor Removal - Vapor is extracted to improve liquid flow through the system and provide diagnostics.


(5)    Outlet(s) - Pure and clean NH3 is provided for accurate metering and distribution.
