ESFR sprinkler systems are the primary fire safety standard in modern warehouses. They provide fast and effective fire suppression without the need for additional in-rack sprinklers.
How does ESFR work?
ESFR sprinklers discharge a large volume of water at high pressure (up to 7 bar) directly onto the fire source. The thermosensitive element activates faster than in standard sprinklers, ensuring a rapid response even with high-bay racking.
ESFR advantages over standard sprinklers
Standard sprinklers only control a fire and often require additional in-rack sprinkler installation. An ESFR system can fully suppress a fire from the ceiling, which means less complex installation and lower maintenance costs.
When is ESFR required?
ESFR is required when the warehouse clear height exceeds 7.5 m and high-bay racking systems are in use. Insurance companies frequently require an ESFR system as a prerequisite for issuing a policy.
