摘要

An apparatus and method to improve delivery of liquid anhydrous ammonia from a portable liquid NH3 tank in cold temperatures includes an air compressor coupled to the vapor port of a portable liquid NH3 tank used to supply liquid anhydrous ammonia to an anhydrous ammonia fertilizer applicator. The apparatus can include an actuator to relieve the tank of compressed air after the tank is empty of liquid anhydrous ammonia.
