SUPERCOOLERS ARE PROBLEMATIC TO ACCURACY. 

....On a 12 shank toolbar 15% additional Nitrogen is applied to two bands. At the 200 lb./A. N rate this is 30 lbs of additional N in each of two dedicated bands. This is 60 lbs of misapplied N summing both bands.

....The coolers require extra maintenance with N-serve. Thus NH3 safety is compromised.

....The coolers can not function at temperatures below 40*F. The two cooler vent lines emit liquid NH3 into the shanks. At temperatures below 45* F accuracy is compromised further and the operator must slow the applicator ground speed.

....The flow from the cooler is errant thus it cannot be effectively injected with single disc openers into the soil. Corn leaves are easily damaged from the escaping NH3 vapor. Shank openers must be used slowing ground speed, disturbing soil and producing more erosion.

....Two 3/4 inch i.d. lines are required from the cooler to the shanks. This -28*F material will easily freeze openers.

....One inch injection tubes are required with sealers. This complicates opener design especially with airseeders that must have excellent separation between the seed and the placed NH3.

SUPERCOOLERS ARE A DOG CHASING IT’S TAIL.

….15 % MORE NH3 IS APPLIED IN TWO BANDS.

 ….AT 40*F THE COOLER VENT LINES BEGIN TO DELIVER LIQUIDAND VAPOR NH3. 

....COOLERS ARE PRONE TO MAINTENANCE ESPECIALLY WITH N-SERVE, 

DIRECT INJECTION TECHNIQUES FOR SIDE DRESSING ARE LIMITED. 

 SHALLOW NH3 PLACEMENT AT 3 INCHES IS NOT POSSIBLE. 

..SHANK/TILLAGE OPENERS ARE REQUIRED TO PLACE THE VAPOR DEEP. 

....SINGLE DISC OPENERS PROVIDE OPPORTUNITIES FOR PLACEMENT SPEEDS TO 10 MPH. 

...COOLERS DO NOT WORK BELOW 40*F MAKING IT
DIFFICULT TO APPLY NH3 IN
THE LATE FALL AND SPRING.

SUPERCOOLERS ARE PROBLEMATIC IN PRODUCING ACCURATE NH3 BAND RATES
