The Khz from recollection will determine the Particle that can be impacted by the Cavitation taking place. A increased Khz Machine will have the potential to remove smaller micron dimension embedment in the Groove. This can be interpreted as a Deeper Groove Clean/Purification The PAVCR Cleaningology Document will offer the most accurate guidance . |
Here are some basic UT rules: 1. Power needed to produce cavitation is inversely proportional to kHz. So, lower kHz requires less power to produce cavitation. 2. Cavitation bubble size is inversely proportional to kHz. So, lower kHz produces a larger diameter bubble. 3. Cavitation intensity is proportional to the bubble size and the power into the tank. So, a KLAudio 40kHz 200W 2.5L UT is a very powerful machine compared to the inexpensive 40kHz, 6L 160W UT machines. A Degritter 120kHz 300W 1.4L UT is a very powerful machine compared to a 6L 120kHz 180W machine. But this is all very simplified because there can be other factors. Of the power advertised, how much actually gets into the tank. The Elmasonic P-series UT tanks are very powerful dual frequency 37/80 kHz and 6L P60H is rated 180W but peak power of 720W, and the tank water from just the UT heats up accordingly. Serial cleaning with the Elmasonic P60H requires an outboard pumped/cooling radiator to keep the fluid temp <100F. Most people find the KLAudio with DIW only (OEM says no to any chemistry) quite acceptable, but some will pre-clean to remove junk from used records, while some people will indicate that without some chemistry, the Degritter may not be effective in removing some tenacious surface fingerprints which can often just be cosmetic.
