These nozzles make a water curtain of 180° spray angle or more.

The flat jet water curtain nozzles UD series operate according to the principle of deflection.

When the liquid passes through the nozzle, and then through the central hole of conveyance, hits the surface deflection suitably inclined and is projected to the outside forming a flat spray.

The distribution has a tapered shape with origin from the center of the nozzle orifice. The deflection surface allows the formation of very large spray angles of 180 degrees or more, in comparison with similar flat jet nozzles from other manufacturers.

The rectangular shape of nozzle, near the orifice, maximize the distance and the uniformity of the water curtain as  a cooiling shield against fire.

These nozzles are ideal in contexts that require a wide angle of coverage during fire-fighting operations, to separate, isolate, control fire growing risks and cool also vertically the areas of interest.

Check with SPRAYTECS for critical dimension, pressure, capacity, fluids in your applications, in order to receive support in your decision.

Nozzle materials must meet correctly chemical composition of fluids in your processes, always remember it.

Spray angle performance varies with pressure. Contact SPRAYTECS for specific data on your critical applications.

  The picture on the left shows the spray pattern of these nozzles.  

UD34W270-F is a water barrier nozzles to protect fuel vessels, with an integrated anti-clogging device.
The spray angle is 120 ° and it is concentrated to protect a specific area..
