Multi-Phase Project From NFPA Research Affiliate Early suppression fast response sprinklers (ESFR) are high-volume, high-pressure sprinklers that are often used to protect combustible storage as an alternative to installing in-rack sprinklers. Compared to the standard spray sprinkler, ESFR sprinklers have a significantly different spray pattern and they apply much larger …
Read More »Early Suppression, Fast Response Sprinklers
Making Them Work for You Since the late 1980s, early suppression, fast response (ESFR) sprinklers have been viewed as one of the greatest innovations in fire protection since Henry Parmelee first introduced the automatic sprinkler in 1874. Since NFPA 13, Standard for the Installation of Sprinkler Systems, indicates that you …
