3 Technical data
3.1 Device dimensions
Fig. 3: Dimensions
3.2 Technical data, general
Description Value
Weight controller 2.4 kg
Operating temperature 0­40 °C
Maximum operating temperature of the nozzle* 120 °C
Average droplet size diameter (depends on sample
properties and process conditions) 50–200 μm
Ultrasonic frequency 60 kHz
Viscosity maximum 50 cP
Maximum flow rate for cooling gas depends on tubing
Feed flow rate minimum 1 mL/min
Feed flow rate maximum 9 mL/min
Recommended maximum particle size in feed slurry 3 µm
*Operation temperature of the system can be higher, however cooling gas must
be supplied to the nozzle to keep the temperature below 100 °C.
