Ultrasonic cleaning unit with a frequency of 37 kHz to ensure an optimal cleaning result. For effective distribution of the ultrasonic frequency, this unit uses the permanent sweep function. Integrated heating element means optimized cleaning, even with the most stubborn contaminations. For efficient and energy-conscious cleaning, both the ‘‘eco’’ and the ‘‘dynamic’’ ultrasonic modes allow adaption to the level of contamination. User-friendly control panel provides monitoring and transparency during cleaning. Stainless-steel tank is highly cavitation resistant, ensuring an extraordinarily long service life. For a disruption-free working environment, the acoustic feedback function indicates when cleaning has been completed. Simple maintenance is supported by easy-to-clean, stainless-steel surfaces and control elements.
