The Power of Crest UltrasonicsThe Powersonic model P1800H-45 @ 115v is a 5.25 gallon ultrasonic heated comes equipped with a Digital display 0-99 minute timer and a thermostat range of 20-80 degrees Celsius (175 degrees Fahrenheit) with 800 watts of heat. With an ultrasonic power top output of 240 watts on average and a frequency of 45 kHz with a sweep of +/- 1.5 kHz.Crest Ultrasonics Brings More Power to You In A Small FootprintThe Powersonic P1800H-45 ultrasonic cleaning unit comes with a 2 year parts and labor warranty. Crest's Powersonic rugged industrial-strength performance gives you consistent quality at a benchtop price. Crest's exclusive Powersonic feature ensures uniform cleaning throughout the tank by sweeping the ultrasonic frequency 3 kHz, creating overlapping ultrasonic waves. This eliminates inconsistent cleaning due to hot spots (areas of intense ultrasonic activity) in the cleaning solution, caused by the unvarying or "standing" waves produced by conventional ultrasonic power supplies.Cleans Like No Other Benchtop AvailableWhen the Powersonic ultrasonic energy is introduced into a cleaning solution, cavitation, the foundation of ultrasonic cleaning, occurs. Ultrasonic energy causes alternating patterns of low and high pressure phases. During the low pressure phases, bubbles, or vacuum cavities, form. In the subsequent high pressure phases, these bubbles implode violently. This is called cavitation. Cavitation provides an intense scrubbing action that leads to unsurpassed cleaning speed and consistency when compared with simple soaking or immersion with agitation. Additionally, the bubbles are small enough to penetrate even microscopic crevices, cleaning them thoroughly and consistently. As a result, ultrasonic cleaning is one of the most highly effective and efficient methods you can use for cleaning a wide array of parts. Many features that add value to your investment have been engineered into Crest's benchtop clean
