    The 3 Tier Driver ability of the SCS 460 will turn on and off different sets of nozzle tiers in order to maintain system pressure as flow increases or decreases. This feature allows for a steady spray pattern. The console will control the tiers through the Tier Driver Interface Box either manually or automatically based on the system pressure.
