ESFR sprinkler heads were developed in the 1980s to take advantage of the latest fast-response fire sprinkler technology to provide fire suppression of specific high-challenge fire hazards. Because they’re smaller than the 5mm bulbs used in standard response sprinklers, 3mm glass bulbs are more sensitive to changes in heat and thus discharge earlier than standard-response heads. During a fire, the heat causes the core of the sprinkler head to burst discharging water. The response time is expressed as a response time index (RTI), which typically has values between 35 and 250 m½s½, where a low value indicates a fast response. [6] It was not until a short time later that, as a result of a large furniture factory that repeatedly burned down, Hiram Stevens Maxim was consulted on how to prevent a recurrence and invented the first automatic fire sprinkler.

The water held back by the bulb then escapes and flows toward the deflector, which disperses it throughout the room. It’s capable of withstanding exposure to a larger number of chemical substances, including hydrogen peroxide, sodium hydroxide, ammonia, and nitric acid. There is no “best” fire sprinkler – only the right model for a specific coverage area’s needs. He increased sensitivity by removing the fusible joint from all contact with the water, and, by seating a valve in the center of a flexible diaphragm, he relieved the low-fusing soldered joint of the strain of water pressure. In short, fire sprinklers are expected to deliver more water while covering a smaller and smaller area as hazards increase.
