Product Description

DN20 Extend Coverage Firefighting Sprinklers

 

Product Description

QR-EC K8.0 Quick Response Extend Coverage Sprinklers are automatic sprinklers of the glass bulb type. They are
quick response, spray sprinklers that produce a hemi- spherical water distribution pattern below the deflector. Higher flow rates can be achieved at much lower pressures with the 8.0 K-factor, QR-EC Sprinklers, making their use highly advantageous in high density applications, such as the protection of high-piled storage.
Chrome coatings can be used to extend the life of the brass components used in Series QR-EC Sprinklers beyond that which would otherwise be obtained when exposed to corrosive atmospheres. Although coated sprinklers have passed the standard corrosion tests of the applicable approval agencies, the testing is not representative of all possible corrosive atmospheres. Consequently, it is recommended that the end-user be consulted with respect to the suitability of these corrosion resistant coatings for any given corrosive environment. The effects of ambient temperature, concentration of chemicals, and gas/chemical velocity, should be considered, as a minimum, along with the corrosive nature of the chemical to which the sprinklers will be exposed.
