Internal Staged Suppression System

摘要

An internal staged suppression system for suppressing a hazard occurring in a grain dryer includes a plurality of vertical column sections and at least one spray head positioned radially inward within the interior of the grain dryer. The spray head includes a deflector cap that generates a substantially horizontal spray of water sufficient to reach the walls defining the grain columns.
