Early-inhibition Quick Response Sprinkler(pendant type) ESFR202/68℃
Executive Standard: GB5135.9-2006
Product Introduction:
Acting as a main component in automatic water spraying and fire extinguishing system, the pendant type early-inhibition quick response sprinkler of ESFR series is the one with large aperture. It is used for detecting fire hazard and putting out fire through spraying water automatically. Carried with the glass ball of ∅2.5mm (∅3mm), large nozzle diameter and relatively large deflector, and the response time index of (RTI)≤28±8（m.s）0.5, it possesses the advantages such as quick fire response, high flow, large water drop diameter, high fire extinguishing efficiency etc., which enables it to be superior to common ones. It is designed dedicatedly for protecting high stacking, store house with high-goods shelf, as well as the warehouse stored with articles of I-IV type, plastic products and mixed articles under general risk.
Specifications:
The response time index forthe device is (RTI) ≤28±8(m.s)0.5
