Spray Nozzles

Open type nozzles are used to protect horizontal or vertical storage tanks, conveyors, horizontal dryers, transformers, cable galleries, escalators and similar hazards against flammable liquid hazards. Systems with open nozzles are controlled by using pressure valves. Protection with water spray is extremely important. When planning protection, the technical data of the nozzle to be used for effective extinguishing or cooling and the manufacturer’s warnings should be taken into account.

Water Spray systems can be designed with manual or automatic control. System design is often realized using Flood valves according to NFPA 15 or API 2030 standards.

Nozzles; MV Medium Velocity water spray nozzles, HV High Velocity water spray nozzles, Water Curtain nozzles, Tank Cooling nozzles, etc. It would be correct to group them.

MV nozzles are used in fixed water spray systems in fire protection applications. MV spray nozzles discharge a water spray of medium velocity water droplets evenly over a designated scanning area for effective extinguishing and cooling.

High velocity (HV) nozzles are mainly used in water spray systems for the protection of stationary hazards such as transformers and circuit breakers.

Water curtain nozzles distribute water evenly all the way to the ground. Water curtains are manufactured and used to separate the area under fire from adjacent areas or the area in which it is located.

Tank cooling nozzles are used for cooling tanks.
