1. Warehouse-type Special Application Nozzle CMSAZ-K202 Description

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