EC-11 (K=161) series large coverage upright/pendent/embedded pendent sprinklers are used in light and medium hazard locations (NFPA13)
Product Description
The EC-11 series of large-coverage upright/sag decorative sprinkler heads are used in light- and medium-hazardous locations and provide 37.2 m2 of protection per NFPA 13, compared to the standard sprinkler head's 12.1 m2 of protection in medium-hazardous locations and 20.6 m2 of protection in light-hazardous locations. UL and ULC allow the EC-11 series of sprinklers to be used in ceiling construction and concrete "T" beam construction where there are no obstructions to water spraying or non-combustible barriers. UL and ULC allow the EC-11 series spray guns to be used in non-spray obstructions or non-combustible obstructions in ceiling structures and concrete "T" beam structures.
The EC-11 large-coverage sprinkler heads have been tested for fire suppression performance against standard sprinkler heads, and the test results show that:
EC-11 large-coverage sprinkler heads provide protection equal to or better than standard sprinkler heads.
In corrosive places with anti-corrosion coating nozzle can extend the life of copper alloy nozzle, although the nozzle has done the standard corrosion performance test, but does not mean that it can be used in all corrosive places, the nozzle installation place of the temperature, the concentration of chemical materials, gas / chemical material flow rate, the corrosive nature of the chemical substances to be taken into account the impact. Therefore, it is recommended that customers inquire further about corrosion resistance when placing an order.
