The medium-speed water mist nozzle is a nozzle that produces atomization through impact. It consists of a frame, a top and a splash plate. When the water flow with a certain pressure passes through the nozzle mouth and hits the top and splash plate, it is decomposed into mist water droplets, and is sprayed outward according to a certain atomization angle. Therefore, medium-speed water mist nozzles are also called impact water mist nozzles, and the common model is ZSTWC.

Medium-speed water mist nozzle product hot spots:

1. Suppress the burning speed, reduce fire losses and reduce the risk of explosion.

2. Water is a cheap fire extinguishing agent and has good economic efficiency.

3. If you are fighting a liquid fuel fire, clean water foam liquid can be added to the water to improve the fire-extinguishing effect.

Medium speed water mist nozzle specifications:

● Atomization angle: 45°, 60°, 90°, 120°, 150° (for water mist nozzles of foam spray fire extinguishing systems, the atomization angle should not be greater than 90°)

● Working pressure: 0.35Mpa and above

● Nozzle material: stainless steel 304, 316, copper, etc.

● Water droplet diameter: Dv0.9~900μm

● Product standards: Made in strict accordance with relevant standards for water mist nozzles

Effective range of medium-speed water mist nozzles:

ZSTWC-90°The spray angle is 90 degrees and the spray diameter is about 4.5 meters when the height is 2.5 meters.

ZSTWC-120°The spray angle is 120 degrees and the spray diameter is about 7 meters at a height of 2.5 meters.

ZSTWC-150° spray angle is 140 degrees and the spray diameter is about 8 meters at a height of 2.5 meters.

ZSTWC-180° spray angle is 160 degrees and the spray diameter is about 7.5 meters at a height of 2.5 meters.

Medium speed water mist nozzle application scenarios:

Medium-speed water mist nozzles are suitable for protecting hazardous areas of flammable liquids, gases and solids with a flash point above 68°C to achieve the purpose of cooling, suppressing and extinguishing fires.

● Factory fire prevention and fire extinguishing

● Shopping mall fire fighting

● Warehouse fire control and extinguishing

●Quickly extinguish fire in liquefied gas tank

● Oil storage tank fire prevention

The difference between medium speed water mist nozzles and high speed water mist nozzles:

The high-speed water mist nozzle has good electrical insulation properties and can put out electrical fires;

Medium-speed water mist nozzles use the impact principle to break down water flow. The degree of atomization of water is poor and the electrical insulation performance of mist water cannot be confirmed, so it is not suitable for fighting electrical fires.
