John Deere Raven AccuFlow™ Vortex and Raven AccuFlow™ Single Cooler

Raven AccuFlow™ and AccuFlow Vortex™ flow sensors enhance nutrient availability, and therefore maximize yield potential by allowing the flow meter and GreenStar™ rate controller to accurately meter anhydrous ammonia (NH3). This accuracy ensures producers’ crops get the nitrogen needed to reach the maximum yield potential.

Many factors determine the yield producers will harvest each year. Most of these factors cannot be controlled, such as the amount of rainfall, temperature, and timeliness of rain.

However, other factors can be controlled by the producer to ensure the crop will reach its full potential during the growing season:

• Nutrient availability
• Seed selection
• Pest prevention

Crops such as corn and wheat require the correct amount of nitrogen to reach their maximum yield potential.

Raven AccuFlow helps to manage input costs

The Raven AccuFlow™ and AccuFlow Vortex™ systems allow accurate metering and application of anhydrous ammonia (NH3). Crops get the exact amount of nitrogen needed for maximum yields, while avoiding over application, enabling producers to control input costs.

The price of NH3 fluctuates and is more expensive than it once was. It is important for producers to manage this input cost by controlling the amount applied.

AccuFlow helps to ensure the correct amount of NH3 is applied to reduce over and under application of NH3. Over application of NH3 is a preventable expense, while under application of NH3 decreases crop yields.

Raven AccuFlow™ system integral to NH3 system

The Raven AccuFlow and Raven AccuFlow Vortex™ systems are integral pieces to the complete anhydrous ammonia (NH3) system.

Both systems provide accurate metering to the established John Deere NH3 solution—all available at John Deere.

The products needed for a complete anhydrous ammonia solution are all available through John Deere:

• Nutrient applicator
• Tractor
• Guidance
• Display
• Rate control
• Section control

AccuFlow accurately applies NH3

Anhydrous ammonia (NH3) is maintained in a liquid form by storing it under pressure in a nurse tank. When liquid ammonia is released from the nurse tank, there is pressure loss due to friction of the liquid flowing through the delivery hoses.

The reduced pressure and change in temperature allow the liquid to boil and convert a portion of the liquid into gas. The gas decreases the accuracy of the flow meter and rate controller.

The Raven AccuFlow™ systems reduce the temperature of the NH3 to ensure it is in a liquid state at the flow meter and can be accurately metered by the rate controller. In addition The Vortex cooler alone delivers 50 gpm (60 percent increased capacity over the current single cooler and 25 percent increase over the current dual cooler system).

Without AccuFlow, operators would not be able to accurately apply NH3.

Everything needed to fully plumb a single section AccuFlow system is orderable through the John Deere price pages. These complete kits will improve installation and ordering efficiency. It is no longer necessary to work with a third-party supplier to fully install an anhydrous ammonia (NH3) delivery system.

AccuFlow Vortex offers machine-specific kits that include all the components needed to operate the  nutrient applicator, such as the Vortex cooler, mounting hardware, hoses, and GreenStar™ Rate Controller harnesses. Kits are available for the following platforms.

• 2410C kit components (assembled single vortex cooler)
• 2510H with dry cart

Machine specific kits provide dealers with all of the hardware and harnessing to equip the 2410C or 2510H Dry with the AccuFlow™ Vortex cooler minus:

• EVA hose
• Vapor hose
• Nurse tank hose
• GreenStar™ Rate Controller (GRC)

AccuFlow Single Cooler kits are configurable to meet producers’ needs and the size and series of the 2510 Nutrient Applicator it is being installed.
