Water Curtain Nozzles
A wide, continuous sheet of water for fire separation, radiant-heat shielding and process curtains.
Water Curtain Nozzles
HD Water Curtain Nozzles are non-automatic open, outside sprinklers intended for the protection of windows, walls, steel beams, columns, roofs and any other structures against exposure fire and heat penetration. Water Curtain nozzles are generally installed with orifice slot pointing downwards direction.
How to choose the right nozzle
Five inputs decide almost every spray nozzle selection. Tell us these and we will shortlist the model.
Spray pattern
Full cone, hollow cone, flat fan, solid jet or fine mist, chosen by the area and the job.
Flow & pressure
Required flow (LPM) at the available pressure (bar) sets the orifice size.
Spray angle & distance
Coverage width at the target distance determines angle and spacing on the header.
Droplet size
Fine for evaporation and gas cooling; coarse for impact, washing and wetting.
Material & connection
Brass, SS 304/316, PP, PVDF or PVC; thread size and type (BSP/NPT) or clip-on.

Full Cone Nozzles
A solid, cone-shaped spray that covers a round area evenly. Used where uniform coverage matters: gas cooling, washing, dust suppression and scrubbers.
Explore
Flat Fan Nozzles
A tapered or even sheet of liquid for line coverage on conveyors, washers, coating lines and spray booms.
Explore
Hollow Cone Nozzles
A ring-shaped spray with smaller droplets than a full cone at the same flow. Preferred for gas cooling, scrubbing and evaporation duties.
Explore
Jet Nozzles
A concentrated, high-impact stream for cleaning, descaling and reaching distant targets.

What is a water curtain nozzle?
Water Curtain Nozzles are non-automatic open, outside sprinklers intended for the protection of windows, walls, steel beams, columns, roofs and any other structures against exposure fire and heat penetration.
Water curtain nozzle uses?
Water Curtain Nozzle distributes water in a flat curtain extending all the way to the ground. Water Curtain Nozzle when mounted in pendent position acts as a window spray nozzle to protect interior walls, windows and other openings of the building which are affected by fire.

Can you supply nozzles to match my existing ones?
Yes. Share the model or a photo, the thread size, spray angle and flow, and we will propose an equivalent.
Which material should I choose?
Brass for general water duties, SS 304/316 for corrosion and temperature, and PP, PVDF or PVC for aggressive chemicals.
Why are my nozzles clogging?
Usually from debris or scale. Add or improve filtration, choose a larger free passage design such as spiral nozzles, and clean nozzles on a schedule.
Do you supply in bulk?
Yes, we supply single replacements as well as bulk orders for OEMs and project quantities.
