Full cone nozzles spray completely within the interior of a circular area. There are two different styles of full cone nozzles: Axial and Tangential. Axial full cone nozzles achieve a uniform distribution of liquid over a circular area. Tangential full cone nozzles have no internal vanes so they are less prone to clogging.
Lechler full cone nozzles have a uniform liquid distribution over the whole circular impact area. The high precision of distribution is achieved by orienting the liquid inlet to the center of the swirl chamber of the nozzle.
Tangential-flow full cone nozzles are suited for spraying liquids with a high amount of particulate matter or for fire fighting applications. The atomizing fluid is tangentially supplied to a swirl chamber, where it is put into rotation. Tangential-flow full cone nozzles are free of swirl inserts. and less prone to clogging. The full cone spray is obtained with the aid of specially arranged grooves, milled into the nozzle bottom, which cause an adequate part of the rotating liquid flow to diverge to the center of the swirl chamber.
Cluster head nozzles achieve a very large surface of the sprayed liquid by adding various finely atomizing single nozzles. Whenever a fine fog-like full cone atomization with relatively large flow rates is necessary, e.g. gas exchange processes, steam cooling or dust suppression, Lechler cluster head nozzles are used.
Lechler deflector-plate nozzles are non-clogging nozzles without swirl inserts. They can be used for fire fighting and broadcast spraying.
Full cone spray nozzles from Lechler provide medium to large liquid droplets for uniform distribution and minimum clogging when using additives and viscous liquids. Companies frequently select this nozzle due to its versatility as it can accommodate a variety of applications. Gain greater levels of spray control and coverage with full cone spray nozzles.
Full cone spray nozzles are often used in washing processes to apply detergents and other cleaning liquids on surfaces as well as spraying water to rinse applications. These nozzles may be used for stationary washing stations, movable lance stations, or installed within enclosed tanks. Applications undergoing washing processes may include packaging, totes, tanks, conveyor belts, produce, or equipment.
Fire protection and suppression applications require spray nozzles to apply water, foam, and other suppression liquids in specific areas. The nozzles provide a deluge of liquid to remove oxygen that feeds the flames while also protecting workers, equipment, and process areas.
Dust control full cone spray nozzles can be used for pollution control measures. These nozzles spray water into the air as the dust interacts with the water's surface and becomes heavy enough to fall to the ground. The spray nozzles remove the airborne particles to clear the air during a range of processes such as mining applications.
Oil and gas companies, as well as applications that use combustible machines, may produce excess gas or heat. Full cone spray nozzles are used for cooling purposes. Gas cooling limits the amount of flue gas that is later expelled into the environment. Temperature cooling is ideal for applications to limit wear and tear to machinery or damage to products.
Selecting the full cone spray nozzle will depend on the desired spray area, liquid type, liquid distribution, droplet sizes, and flow type. Customers who desire a large spray area with full coverage can take advantage of this nozzle type. They provide medium to large droplets for full saturation and even distribution. These nozzles can also handle large flow rates for continuous application.
This spray pattern offers full distribution within the entire cone radius instead of just the edges. It allows better coverage and control of liquid droplets in medium and large sizes. Full cone nozzles allow for free passage of liquids, as they can accommodate viscous liquids with additives and particulates. Full cone spray nozzles can be used for specific areas for close coverage when washing and rinsing applications, or large spaces for fire suppression, gas cooling, foam control, dust suppression, and temperature control.
Lechler spray nozzles come in a variety of spray designs to handle varying flow rates and liquid distribution specifications. We work closely with customers to determine the appropriate nozzles for the application and can design nozzles for new or existing equipment processes.
