AccuFlow and AccuFlow HP Plus

Raven has raised anhydrous ammonia (NH3) application technology to new levels of performance with the AccuFlow Vortex cooler and AccuFlow HP (high performance) Plus. Both models use super cooling technology to stabilize NH3 as a liquid for superior accuracy and control.

Paired with your Raven control system, AccuFlow Vortex super cooling NH3 technology replaces the dual cooler system to give you superior accuracy and control over your applications for higher yields, less waste and lower input costs.

Raven’s advanced NH3 cooler system is now available in stainless steel and with more capacity options!
