Ultrasonic Atomiser

The Ultrasonic Atomiser uses Ultrasonic energy (Low/Medium) to generate low velocity, gentle spray unlike the conventional atomizing nozzle which depends on pressure & high velocity motion to shear a fluid into small droplets. The fluid (Liquid) is dispensed to the atomizing probe by either gravity or low-pressure small pumps & atomize continuously or intermittently as per requirement. The sample can be accurately delivered to the target area & over spray is virtually eliminated thus, resulting in material savings. The atomizer can runs continuously or be programmed to pulse On & Off.

The rate of atomization depends within limits solely on the volume that is been delivered onto the atomizing surface & the frequency it operates. Typically higher the frequency, the lower the processing capability. With water the average droplet size is 50 microns and the minimum sample volume that can be effectively atomized is 2µl/sec. To optimize atomization, the viscosity below 50cps & solid concentration must be below 30%.

The atomization of liquids containing long-chained polymer molecules is problematic, even in diluted form, due to highly cohesive nature of the material. Drop size is primarily a function of frequency, and the higher the frequency, the smaller the drop diameter, E.g. : frequency 20 kHz the drop size is 100 microns & frequency is 40 KHz the drop size is 50 microns.
