Logo About Ultrasonic Cleaning Ultrasonic cleaning can remove contaminants--such as grease, oil, wax, fluxes, fingerprints, oxides and other deposits--from visible and invisible surfaces, holes and cracks. In general, if an item can be cleaned with a liquid, it can be cleaned much faster and more thoroughly with an ultrasonic cleaner. It may not be possible to clean certain intricate and complex parts without the use of an ultrasonic cleaner.Ultrasonic can deal with physical problems but cannot deal with chemical problems. These items will become duller over time and they are usually oxidized or produce certain types of chemicals.If the silver has turned black, simple ultrasonic cleaning is not enough, need to add professional cleaning agent.Different ways of cleaning: 1. General Cleaning - only use warm and fresh water, warm water's temperature is about 50 centigrade. 2. Enhanced Cleaning - add a few drops of standard liquid soap or detergent into the water, some basic non-acidic cleaning agents can be used as well. 3. Extensive Cleaning - Removing tarnish, carbon and rust from non-plated metals. It is recommended to use specialist cleaning solution in associated using Ultrasonic cleaner. Product Description Product details Ultrasonic Power:160W Heating Power:150W Voltage:110V-120V Material:Stainless Steel SUS304 Tank Capacity:3L / 238*138*100mm(9.37*5.43*3.93 inch). In reality its about 2.7L for water (when its filled to the very top) Frequency:37KHz Unit Weight:4.2Kgs 1.Pulse Continuous tracking to the resonant frequency for a long time to achieve peak output of ultrasonic power. The actual performance is that the ultrasonic continuous impact the items, enhance the effect of ultrasonic cleaning. 2.Sweep In general, the ultrasonic distribution of traditional machines may not be able to throughout the tank, resulting in small ultrasonic power in some areas.Sweep function can make a uniform distribution of the ultrasonic power throughout the tank, to meet higher cleaning requirements. 3.Degas Air in the liquid affects cavitation and reduces ultrasonic power.Degas can quick degassing of cleaning liquids,the resistance of bubbles produced by ultrasonic cavitation reaction will reduced and the ultrasonic cleaning effect will be better. 4.Power adjust Power can be adjust 3 gears 40%-70%-100%. Warning Please operate according to the specifications of the manual, especially pay attention to the red text in the manual. Cleaning jewelry items: For diamond inlaid jewelry, extended periods of cleaning are not suitable; if the cleaning time is too long, the diamonds may fall off. These items will become duller over time and they are usually oxidized or produce certain types of chemicals.If the silver has turned black, simple ultrasonic cleaning is not enough, need to add professional cleaning agent. Tank material is SUS304 1mm,but do not use strong acid, alkaline or corrosive liquids, strong acid and alkaline cleaning will cause corrosion,rust and even puncture of tank or machine body. If you want to use strong acid and alkaline cleaning agent, please use a beaker, pour the acid and alkaline liquid into the beaker, and put the items to be cleaned into the beaker, then put the beaker in the basket. 2l ultrasonic cleaner 3l ultrasonic cleaner 3L ultrasonic cleaner with power adjustable Add to Cart Add to Cart Add to Cart Customer Reviews 4.1 out of 5 stars 25 4.1 out of 5 stars 10 3.4 out of 5 stars 6 Price $120.00$120.00 $153.30$153.30 $158.00$158.00 Model DR-DS20 DR-DS30 DR-P30 Ultrasonic Power 80W 160W 160W Heating Power 100W 150W 150W Frequency 37KHZ 37KHZ 37KHZ Tank Size 2L/150*138*100mm 3L/238*138*100mm 3L/238*138*100mm Basket size 130*120*65mm 218*120*65mm 218*120*65mm Timer 5-30min 5-30min 5-60min Temperature 30-80℃ 30-80℃ 30-80℃ Product Show The Front Mechanical knobs control time and temperature, button control switches, and Degas and Sweep features.
