ETL APPROVED! ETL is a mark provided by Intertek, a Nationally Recognized Testing Laboratory that is found on our washer where ETL tests products to UL, CSA and CE standards. A product bearing the ETL Listed Mark is determined to have met the requirements of prescribed product safety standards as well as where our factory conforms to a range of compliance measures and is subject to periodic follow-up inspections to verify continued conformance.
NOT ALL ULTRASONICS WASH YOUR RECORDS SAFELY: SPECIFY 35 KHz!
"Sonically speaking", INDEED where higher the frequency, the smaller the bubbles, smaller the bubbles, they enter small crevices easier. A RECORD CONTRARY TO BELIEF IS NOT A SMALL CREVICE. MINUTE DETAILS WITHIN THE GROOVE PROVIDE TIMBER AND THE EXCELLENCE OF ANALOG.?THESE INDENTATIONS SHOULD NEVER BE REMOVED! In 3 years of testing, 35 kHz is the sweet spot, does not remove these details and does not "smoothen" the grooves as would a poorly designed recoird clkeaner leaving a residue which has the same effect. Not 45, not 80, not 90 kHz. NEVER 120 kHz or higher. All are proven to damage records over time. Much misinformation out there: We have in house experienced engineers familiar with ultrasonic generation. ?35 kHz is gentle yet powerful to do the job!
A Primer on Sonic Technology:Under pressure of continuous vibration by the ultrasonic generator at the bottom of the tank bubbles generated rise and stretch and compress at a fast rate. Once they reach a certain size as determined by the frequency and strength of the sound waves produced the bubbles lose structural integrity and collapse violently. When these implosions happen near the surface of an object such as a record, the bubbles emit high-powered streams of plasma that travel at more than 500 miles per hour and collide with, agitate and remove even very tiny particles and substances from the record's surface. Using a surfactant attracts further these bubbles to the record. (For new records, 40 mL of 70% alcohol per 6 L of distilled water to remove record pressing residue, our 1% propanol surfactant brushed in for mildly to generally abused records). CALLED CAVITATION: In an ultrasonic cleaning machine, explosions occur millions of times per second, removing contaminants. Bubble size relates to how much energy is released when they implode. That’s why a higher frequency produces less intense cleaning, (smaller bubbles) but because a higher frequency yields more bubbles it’s a better choice for cleaning parts with very tiny features such as blind holes, channels and threads. This a danger for vinyl and shellacked records. ?SMALL BUBBLES DAMMAGE THE DEPTH OF THE GROOVE REMOVING TIMBER AND HIGH FREQUENCIES. THE BEST ULTRASONIC FREQUENCY AFTER 3 YEARS OF TESTING IS 35 kHz WITH A MAX TEMP OF 95 DEG F. Higher frequencies such as 100, 125, 130 kHz are used for fine cleaning jobs as they enter small surfaces including microelectronics, printed circuit boards, medical and precision optics. powerful explosions remove post manufacturing matter and dirt. The 35 kHz frequency has a good combination of power, penetration, and especially very even energy distribution and can successfully address most cleaning applications when combined with a properly-engineered cleaning system and also does not damage the stainless steel basin as do higher frequencies.
MORE MYTHS REVEALED: AS TO OTHER SYSTEMS CLEANING 6, 8, 12 OR MORE RECORDS AT A TIME AND UNDERSTANDING
THE KIRMUSSAUDIO SYSTEM HAS ITS RECORDS SPACED AT THE CORRECT DISTANCE BETWEEN EACH OTHER TAKING ULTRASONIC FREQUENCY, ULTRASONIC POWER TO THE CERAMIC SONIC TRANSDUCERS LOCATED AT THE BOTTOM OF THE STAINLESS STEEL BASIN WITH MEASURED BUBBLE GENERATION AND THE RESULTING CAVITATION EFFECT TAKEN INTO CONSIDERATION. KIRMUSS THUS ENGINNERED THEREFORE A SYSTEM WHERE 4 RECORDS ARE SAFELY AND PROPERLY CLEANED WITH ALL GROOVES CONTACTED WITHOUT WETTING THE LABEL. OUR SPECIFIC SPACING IS DESIGNED WHERE A MAXIMUM OF 4 RECORDS ARE CLEANED SIMULTANEOULSY IN A 6 LITER, 1.6 GALLON TUB. ANY MORE RECORDS ADDED IN THE ASSEMBLY WOULD SEE THE RECORDS CLOSER TO EACH OTHER AND AS A RESULT GROOVES NEAREST THE WAX RELEASE POINT AT THE END OF RECORD WOULD NOT BE CLEANED AS WE SEE IN OTHER SYSTEMS OFFERING 6, 8, EVEN 12 RECOIRDS BEING CLEANED AT A TIME. AS WE HAVE DISCOVERED USING UNDERWATER CAMERAS, THE HIGHER THE NUMBER OF RECORDS SPACED CLOSER THAN 1 3/4" AND LESS SEES THE SONIC BUBBLE IMPLOSIONS CANCEL OUT AS BUBBLES RISE AND APPROACH THE WAX LINE AND AS A RESULT, WHERE 2/3 OF THE RECORD WOULD NOT BE CLEANED. It's called SCIENCE!
