K25 Pendent Upright ESFR Early Suppression Fast Response Brass Fire Sprinkler for Firefighting
ESFR nozzles are used to protect the closed nozzles of high stacking and elevated warehouses. It can make a quick response to the fire, and achieve the role of early suppression or extinguishing the fire. ESFR sprinkler head is suitable for use in places with high fire risk level; When used in elevated warehouse, it can release a lot of water and has good shelf penetration. Without adding the in-shelf sprinkler head, it saves the storage trouble caused by the in-shelf sprinkler head and does not have to worry about the damage of the in-shelf sprinkler head. Therefore, ESFR sprinkler system is more cost-effective and convenient to install.
