Percussive-type spray nozzle ZSTWC 
 We supply spray nozzles percussive 
 Percussive water fog mist system is an important part, when a certain pressure of water flow through the nozzle, hit the apex and the deflector is broken down into the spray mist of water droplets and press the point of playing in a certain set protection of the outer surface of the object in order to achieve cooling, fire suppression and fire-fighting purposes. The cooling effect is more significant, impact-type spray nozzle main features: through heat, promote and distribute the steam dilution to reduce the burning rate and reduce the risk of explosion and fire damage.
