Performance Data

COMMON APPLICATIONS 
Middle-low water mist system for fire suppression, suitable for CLASS A，CLASS B fire, Cable Fire, Electrical Cabinet Fire.
Suitable for class A and class B and electrical fire, such as libraries, archives, mechanical equipment, electrical equipment, high and low voltage distribution room, power transformer room, outdoor transformers, computer and telecommunication room, diesel generator room and storage, fuel gas boiler room, cable interlayer, cable tunnel, underground tunnels, subway control center and other places.

Note
The spray angles, diameter of droplets and spray curve are obtained from test atrated pressure.
1) Factor-K is defined as following: K=Q/sqrt(10), Here, Q is the flow rate with its unit as L/min; P is the operating pressure with unit Mpa; Tolerance of K should be within ±5%.
2)The vertical spray curve is shown below. Variation range of spray angle α should be within ±10°, size B and C will alter as size A    alters. So the data in the chart above are obtained from test at rated pressure.

3) The horizontal spray curve is shown below. The data in the chart above are obtained from test at rated pressure.
