Atomizing Spray Nozzles

Sonaer^® ultrasonic atomizer nozzles are a flow through design. Liquid is pumped at the rear of the probe and travels down through the center until it reaches the vibrating tip. Once the liquid reaches the tip portion of the nozzle, ultrasonic vibrations pulverize the liquid into ultra fine particles for precise coating applications without the use of air pressure.

In the center of the probe are piezo ceramics which convert the electrical signal to mechanical vibration. This vibration is amplified by the step that forms the tip of the probe, and is reflected back towards the piezo ceramics , mixes with outgoing waves, creating standing waves. These standing waves cause a pumping action that sucks liquid towards the center of the probe.

With the Sonaer atomizer probe design, liquid will spray continuously, will not flow back into the probe from these standing waves, creating a sudden spurt of liquid, called "flashing". The spray from these atomizers will be smooth and controllable with very little over spray. Spray thickness is nano - microns which is all user adjustable. The thickness is set by the pumps flow rate or shot, power level of the nozzle, liquid characteristics and the time the substrate is exposed to the liquid. For heavy coatings use low frequency probes, for ultra thin coatings use the higher frequency probe nozzles listed below.

Sonaer's atomizer nozzle generator is state-of-the-art, with surface mount components throughout, unique software algorithms making the generator 100% digital which allows the nozzle to be controlled by a PC with "Auto Atomization Power Adjustment" (AAPA) capability. AAPA automatically adjust the power output to the nozzle with changes in liquid flows without stalling as with all other atomizer nozzle suppliers. The nozzle generator can also be operated by the customer through .dll file protocol if desired and has infinite frequency control for changes in temperature, loads and operates all other manufacturer atomizer nozzles. Many features of our protective software tells the user if the power is too low for the liquid flow, disables power for any fault with information provided to the user on a LCD display.

Sonaer will custom make 304 or 316 stainless steel nozzles and components for customers who require these materials as a special order. Any frequency nozzle ( 20kHz - 60kHz) can be designed and made from these materials. Flow rates maybe different from the list below. Seals can be either Viton or PTFE Teflon. Probe case, tube and back cover can be made in stainless steel. See DWG below for standard materials.

The tube connection at the rear is for a 1/8" diameter Swage-lock, not included, allowing connection of various fittings and manifolds for introduction of multiple liquids and gases.

These ultrasonic atomizer nozzles have the widest spray pattern due to the tip design. 20kHz-60kHz nozzle have an upside down umbrella shape tip whereas the 120kHz and 130kHz nozzle has a convex tip shape. Sprays in the ul range will be similar to the Narrow series below and will get wider as the flow rate increases. Drop diameter provided is with the Lang formula below. For actual measured particle data using a DCIII particle counter see DATA link next to each nozzle. 3D .pdf model for each nozzle . All nozzles can be provided with cooling ports for spray shapping, applications for elivated temperatures or for keeping piezo crystals lower then 150 deg C (302 deg F) add CP at the end of the model number. For dual liquid port 30kHz nozzle add DP at the end on model number

The narrow spray ultrasonic atomizer nozzles have the narrowest spray pattern due to the flat tip design. This atomizer nozzle is very popular for extra low flows in the ul/min range. Drop diameter provided is with the Lang formula below. For actual measured particle data using a DCIII particle counter see DATA link next to each nozzle. All nozzles can be provided with cooling ports for spray shapping, applications for elivated temperatures or for keeping piezo crystals lower then 150 deg C (302 deg F) add CP at the end of the model number.

Sonaer's high temperature atomizer nozzle can be used in an environment where the tip temperature can reach as high as 1000 degrees F. Along the tip extension is a thread for attaching to a chamber being heated. This atomizer is good for fuels being burned and high temperature spray drying. All nozzles can be provided with cooling ports for spray shapping, applications for elivated temperatures or for keeping piezo crystals lower then 150 deg C (302 deg F) add CP at the end of the model number.

The wide spray ultrasonic atomizer nozzles have the widest spray pattern due to the tip design. Sonaer's 40kHz-60kHz nozzle have an taper at the end of the tip. Sprays in the ul range will be similar to the Narrow series below and will get wider as the flow rate increases. Drop diameter provided is with the Lang formula below. For actual measured particle data using a DCIII particle counter see DATA link next to each nozzle. All nozzles can be provided with cooling ports for spray shapping, applications for elivated temperatures or for keeping piezo crystals lower then 150 deg C (302 deg F) add CP at the end of the model number.
