Hollow Cone Spray Nozzles
Hollow Cone nozzles produce a circular spray where the liquid is distributed around the perimeter or circumference of the circle. They generate fine droplets. There are many different hollow cone nozzles available but they can be broadly divided into 4 basic types – Tangential Spray, Axial Spray, Deflection Type Axial Spray, Hydraulic Atomisers
Tangential Nozzles Type PA/PB; PE/PF
These nozzles work on the tangential flow principle where the centrifugal force inside the whirl chamber provides the energy for liquid breakup. As they have no internal vanes they are not susceptible to clogging and so are ideal when using recycled water or when there is solid matter in the liquid.Typical Applications: gas and smoke scrubbing, cooling of large tanks and storage vessels, humidifying, dust suppression, foam control, fire fighting, chemical process engineering.
Connection: 1/8″ to 2 1/2″ BSP
Spray angles: 50° to 130°
Material: 303 Stainless Steel, 316L Stainless Steel, Brass
Tangential Nozzles Type PN/PO
This range of hollow cone nozzles are made from tough glass fiber reinforced polypropylene for high mechanical strength and dimensional stability. They offer good corrosion resistance and moderate price. Together with their special polypropylene pipe clamps they offer the best solution in all cases where large quantities of nozzles have to be easily assembled onto pipe manifolds. The maximum recommended operating temperature is 75 degrees C.Typical Applications: air humidification, gas scrubbing, dust suppression, foam control.
Connection: 3/8″ to 1/2″ BSP
Spray angles: 70°, 130°
Material: Glass fibre reinforced polypropylene
Axial Spray with Swirl Vane – Type RA
These nozzles have an internal vane with two precision machined spiral grooves and produce a very fine spray in line with the inlet pipe.Typical Applications: dust suppression in coal mines, cooling and scrubbing of air and gas, desuperheating steam, spray drying.Connection: 1/8″, 3/8″ to 1/2 ” BSP
Spray angles: 60°, 80°, 90°
Material: 316L Stainless Steel, Brass
Axial Spray Without Swirl Vane – Type RB
The RB nozzles work on the tangential principle and produce a hollow cone spray pattern, in line with the nozzle inlet pipe. Having no internal vane minimises the danger of clogging while still producing fine droplets. They are especially suited to dust suppression applications in coal mines.Typical Applications: dust suppression in coal mines, cooling,
Connection: 3/8″ to 1 1/2″ BSP
Spray angles: 60°, 70°, 80°
Material: 303 Stainless Steel, Brass
Deflection Type Axial Spray – Type RC
RC nozzles produce hollow cone spray pattern with very wide angles perpendicular to the inlet pipe. The spray is produced by deflection of the water flow against a fixed plate in front of the nozzle orifice.Typical Applications: fire fighting, cleaning or spraying inside pipes and cylinders.
Connection: 1/4″ to 3/8″ BSP
Spray angles: 150°, 180°
Material: 303 Stainless Steel, Brass
Hydraulic Atomisers Type RX/RZ
Hydraulic atomisers are designed to deliver a very finely atomised hollow cone spray even at low pressures. The nozzles contain a precisely machined insert with tiny passages, which can be disassembled for cleaning should the nozzle become clogged. Protection against clogging can be achieved by fitting a strainer on the inlet. Flow rates range from 0.06 to 2 l/min @ 3 bar.Typical Applications: humidifying processes in the textile industry, dust suppression, air moistening.
Connection: 1/4″ BSP
Spray angles: 30° to 90°
Material: 303 Stainless Steel, 316 Stainless Steel, Brass
