Nurse Tank Connection- The Equaply™ system requires an Acme coupler with high flow globe valve at the nurse tank. A 1¼" anhydrous ammonia hose connects to a high flow breakaway at the inlet to the heat exchanger. For high flow rates, the use of dual tanks is suggested, particularly during cold weather. Also, we recommend that your fertilizer dealer install high flow 1¼" valves on the tank outlets in place of the  usual 1" valves. The Equaply™ system does not require bottom outlet tanks.

Heat Exchanger-  

In systems without pumps, vapor makes most flow meters inaccurate. A heat  exchanger cools anhydrous ammonia below its boiling point and condenses the vapor phase to a liquid. Once liquid pressure has been increased by the pump, the anhydrous ammonia is at a pressure that has a significantly lower boiling point. The Equaply™ uses specially ported Hiniker heat exchangers for increased flow. Our larger flow models have two heat exchangers in parallel. 　A basket strainer after the exchanger catches solids from the nurse tank. A strainer after the pump collects particles that could clog  an orifice. A safety valve protects against over pressurization from solar heating when a charged system is not in use.

Pump- The pump assembly is perhaps the most important part of our system for equal distribution.  We use a Hypro centrifugal pump with a hydraulic motor because it doesn't surge like piston pumps. The  pump keeps anhydrous ammonia as a liquid until it can be evenly split at the manifold. This is important because vapor affects distribution as it takes the easiest path. For example, if there is a circular manifold on a toolbar which tilts down to the left on a hillside, vapor will tend to go out of the hose barbs which are  up and to the right.　 For custom applicators, the most important reason for a pump is the ability to apply  at full rate when it’s cold. Standard delivery systems have to slow down during late fall and early spring, when temperature and tank pressure are low, to achieve a desired application rate.

Flow and Measurement Control- The Equaply™ uses a Hiniker or Raven flow sensor and servo valve. Signals from the flow sensor go to a cab console which operates the servo valve. The flow sensor has maximum accuracy because it sees only liquid.　 We also offer systems with flow meters and servos to interface with AgLeader Insight, Raven, and John Deere Greenstar II. To verify equal row distribution, we highly recommend a gauge tree to monitor flow to the individual rows.　

Manifolds and Orifices- After the servo valve, anhydrous ammonia goes to one or more manifolds controlled by an electrically operated on/off valve.　 TeeJet orifices at the manifold are housed in special fitting assemblies which allow the use of conventional 3/8" EVA ammonia tubing or smaller Teflon® tubing sizes.　 The fitting assemblies also connect lines to the gauge tree.
　　　If large rate variations are necessary, we can widen the range with Impellicone manifolds.　 At lower rates, the manifolds will be dividing a mix of liquid and gas which is inherently less accurate than dividing liquid alone.　 However, the Impellicone manifolds are the best possible way to divide this  mixture so you will still get reasonable distribution row to row.
