Industrial Spray Nozzles by BETE®
In all areas of spray nozzle engineering, manufacturing, and application, BETE Industrial Spray Nozzles is a pioneer. Ever since 1950 when John BETE invented the spiral nozzle, their spray nozzle design innovations have gone into deep sea, deep space and everywhere in between.
In 1993, they were the first spray nozzle company to have its quality management system registered to ISO 9001. In 2003, they became the first spray nozzle company in the world with a quality management system registered to the demanding ISO 9001:2000 standard. Additionally, in 2009, our quality management system registered to the ISO 9001:2008 standard.
Flat Fan nozzles
Flat fan nozzles produce a line of spray. They are often used in coating and cleaning applications on conveyors where product is passed under a spray bar of several fan nozzles. There are two main designs of fan nozzle: deflection and a standard shaped orifice.
Hollow Cone Nozzles
Hollow cone nozzles produce a ring of spray. This spray pattern will generally consist of the smallest droplet sizes of any spray pattern. Three designs of nozzle can be made to produce hollow cones: spirals, axial whirls and tangential whirls.
Full Cone Nozzles
Full cone nozzles produce a solid circle of spray. These nozzles are used when the objective is to distribute the fluid evenly over an area. As with the hollow cone nozzles there are three designs of nozzle that can produce full cone patterns.
Mist or fog patterns are characterised as having the fluid finely atomised with little or no momentum. A homogeneous fog is produced that will largely be directed by any surrounding air flows rather than by the nozzle itself. There are two design types that produce this pattern: impingement and small orifice.
The tank cleaning “pattern” requires fluid to be delivered to the whole area of a vessel that needs cleaning. Typically this means a 360° delivery of fluid. There are 3 basic designs of tank cleaner that will achieve this: rotary jet cleaners for high impact, rotary fan cleaner for medium impact and static cleaners for low impact.
Air atomising is not a pattern as such. The use of air to break apart a fluid is a fundamental change to the way standard pneumatic nozzles operate and so air atomisers warrant their pattern section. All patterns, except solid stream, can be created by air atomising nozzles and there are various designs variants within the group.
Special Purpose Nozzles and Accessories
Applications with very specific requirements require specialised nozzles. Nozzles for fire control, spray drying, submerged tank mixing, the paper industry, and air blowoff are some that require application-specific designs.
