The Sonixtek AU Advanced Series heavyduty industrial ultrasonic cleaners are designed to be used in the most demanding industrial environments where powerful cleaning is required. This range can be used in all industrial processes such as power and heat plants, garages, mechanical industries, electronic workshops, aerospace component manufacturing, weapon industries, chemical processing industries, manufacturing industries and many more. 

The AU Advanced Series integrates numerous innovative and state-of-the-art functions controlled by a 24 IO Siemens PLC and 7-inch Siemens touchscreen with capability for remote analysis and problem identification either via wired or a wireless secure network over the internet. 

The comprehensive operation offers numerous options and settings via the touch screen such as PLC controlled water flow system, agitation function, lift system with precision motor, multitemperature sensors that monitor temperature in the tank, automatically controlled fill system, water level sensors, automatic lid, etc. 


7-inch Siemens Touchscreen and Siemens PLC  

Filtration system with laminar flow system and oil skimming system  

Double filtration system with laminar flow system and oil skimming function ensures separation and filtration of contaminants and oil, which not only allows the cleaning bath to be used several times but is also environmentally friendly 

Thermal and acoustic insulation  

The thermal and acoustic insulation ensures that the tank heats up faster and maintains its temperature in an ecological manner while the sound insulation reduces the noise level

Time Saving 

Ultrasonic cleaners can remove contaminants faster and better than other types of cleaners. 

Contaminant Removal 

Ultrasonic cleaners can remove an endless variety of contaminants. 

Complex Microscopic Cleaning 

The use of high-frequency waves and cleaning detergents improve the overall cleaning action, reaching all surfaces even at the tiniest crevices. 

Gentle Cleaning 

Ultrasonic cleaners remove contaminants without abrasion or scrubbing. 

Low Power Consumption 

Cleaning is done through efficient electrical energy and transducers, keeping power consumption to a minimum.  

Environmentally Friendly 

Reduction/replacement of hazardous solvents and a lower total energy consumption.
