NH3 (Anhydrous Ammonia) Pull Away Riser Safety Shear
The NH3 (anhydrous ammonia) pull-away riser safety shear, or A-RSS, protects your riser from accidental pull-aways by incorporating a shear device that breaks when someone accidentally drives away while the filler hoses are still attached to the anhydrous ammonia tank. The two back checks are positioned so that when a pull away occurs it stops the ammonia from spraying out of the riser and the tank. This is the same PROVEN shear technology we built in to the P.A.S.S system in 1991. Not one failure has ever been reported since its introduction.
