CMSAX Warehouse-Type Special Application Sprinkler

1. Description of CMSAX (Warehouse-Type) Special Application Sprinkler

The CMSAX warehouse-type special application sprinkler is a high-flow special sprinkler designed for high-stacking or high-rack warehouses. Compared to ESFR sprinklers, it aims to control fire spread, operates at a lower minimum working pressure than ESFR sprinklers, and is less affected by obstacles in water distribution. Facilities equipped with this series of sprinklers do not require additional in-rack sprinklers. Additionally, this series can be used in dry systems and pre-action systems.
