Warehouse sprinklers are designed for special applications such as high level water storage systems. This type of sprinkler provides more water under low pressure. If the user has the correct pressure adjustment for the ESFR sprinkler, there is no need to use any other sprinklers between the ladders.

        This type of sprinkler is designed to prevent the ladder from breaking. When using, users should pay attention to their characteristics. The waterproof cover is very important for heat detection. If the water hood is not used in the sprinkler system, the sprinkler will not reach the required heat and will not start.

	ESFR (early suppression fast response) sprinkler ESFR has three differences compared to other sprinklers: Speed - ESFR sprinklers have twice the heat detection and start-up time than other sprinklers; Spray volume - other sprinklers can spray water 25-60 gpm, while ESFR can spray water 100 gpm; Water Drop Size - ESFR has large water droplets and flow rates compared to other sprinklers.
