Design Features
Very fine droplet size, Class I water mistMajor parts include nozzle body, nozzle tips, whirl core, spray
orifice, strainer mesh
High spray momentum, good ability for penetration of fire
Very fine atomizing droplets, Good dispersion effect
Fog-like droplets remain in air for long time
Note
1. K factor is defined as following:
K=Q/sqrt(10P),
Here, Q refer to the flow rate (L/min) and P refers to the operating pressure (Mpa). Tolerance of K
factors in product standard should be within ±5%.
2. Both the Max. Spacing and Max. Height refer to total applications.
3. DS Series Water Mist Nozzles Model Instruction:
DS-O-48-4-00-1.19 / 10
DS-Serires NO.
O----------------Nozzle types "O" refers to open type nozzle while "C" refers to closed type nozzle.
48---------------The angle between micro nozzle and horizontal ceiling
4-----------------Quantity of micro nozzles
00---------------Temperature of thermo buld,"00"stands for open type
