Ammonia applicator pumps fast with single cooling system

The Accuflow Vortex pumping system can apply up to 80 US gallons a minute

LOUISVILLE, Ky. — A new anhydrous ammonia system puts nitrogen down more quickly than previously possible.

Raven Industries’ applied technology division released its new flow cooler and pumping system in Louisville, Kentucky, earlier this month.

The Accuflow Vortex is the first on the market to have high capacity using a single cooler.

Matt Burkhart of Raven said the new tool is aimed at commercial applicators and larger acreage farmers such as those in Western Canada.

Gary Esselink introduced the new product at the National Farm Machinery Show.

“When you want to apply more anhydrous faster and at colder temperatures, this is how you do it, and we kept the complexity and the weight down,” Esselink said.

“We can get to 50 US gallons a minute and beyond. Add the pump and we get over 80 gallons.”

It almost doubles what the company could previously do with a pair of coolers.

The result is applying 300 pounds of nitrogen at 10 m.p.h. on a 60 foot tool bar.

When used on an 80 foot single pass drill at five m.p.h., it can apply more nitrogen than most producers would care to invest in a canola crop.

The company surveyed commercial operators and large farms from the Midwest to Western Canada to determine what was needed to improve their application processes, and Esselink said almost all of them wanted more capacity, better serviceability and more safety features.

The new design is much smaller than previous models. It has few pipe fittings and joints — typically 30 instead of 50 — and the company has moved to groove lock connectors rather than a two-wrench pipe fitting connection.

“There’s a lot of new software, too,” he said. “Windows for application are getting tighter with more land to operate. There isn’t any room, especially if you are (banding).”

The new single cooler comes with a new Accuflo HP Plus pump that is widely variable and allows for highly precise application of the anhydrous ammonia.

New safety features include improved gauges and stainless steel pipe and a pressure transducer that alerts the operator if an over-pressure situation is developing.

Operators can see from the cab if the valves are open, and a secondary relief valve allows for system draining in about a half hour compared to the two or three hours it takes for the system to bleed off.

Raven said the unit is ISObus compatible, meaning that many current cab information systems and controllers can work in conjunction with the new design.

It said the units will begin shipping in the next couple of weeks.

The Accuflow Vortex costs $5,895 US for the new cooler with a single controller valve, $6,295 when a second, on-off valve is added and $10,295 with the new pump.
