COMMON APPLICATIONS:
Middle-low water mist system for fire suppression, suitable for CLASS A,CLASS B fire, Cable Fire, Electrical Cabinet Fire.


Note: The spray angles, diameter of droplets and spray curve are obtained from test at rated pressure.
1) Factor-K is defined as following:
               K=Q/sqrt(P),
where, 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.
