Capstan NJect NH3 Ag System

posted in: Ag Spray News | 0

NJect technology uses PWM (Pulse Width Modulation) technology as a simple, clever way to change the flow through an orifice as if the orifice size could be changed “on-the-go”.  It responds as needed up to a 25:1 range of rate for a variable rate map prescription.

NH3 fertilizer is fed by supply tank pressure to the input of the NJect distribution manifold.  The manifold consists of aluminum alloy core slices that each have two product outputs ports.  Stacked and bolted together these manifold slices are added to match the particular applicator configuration.  Flow from each output port is metered by a PWM solenoid to tubes leading to the ground engaging tools.  This manifold serves 3 functions:

Accurately distributing the product to the ground engaging tool

Serves as the NH3 cooler.  The liquid/gas NH3 from the supply tank chills the manifold and condenses to the liquid form collecting in the bottom in the manifold.   The PWM solenoids then meter the NH3 in liquid form.

Provides pressure information to an electric flow meter module in the NJect computer.
