In many instances we at Tovatech get interesting tips from our customers.  Here’s one related to multi-frequency ultrasonic cleaners:

If you build, repair or service components that require ultrasonic cleaning you know that one size does not fit all when it comes to ultrasonic frequencies employed. 

By doing a little research I found I could use two ultrasonic cleaners to carry out all the ultrasonic cleaning operations normally employed in my shop. 

These versatile Transsonic TI-H multi-frequency units by Elma and available through Tovatech LLC are produced in a variety of bath sizes.  All models are available operating in two frequencies – a choice of 25 and 45 kHz or 35 and 130 kHz.  For me they cover the spectrum across intensive industrial ultrasonic cleaning to delicate operations such as an ultrasonic jewelry cleaner.

For example my 25/45 kHz industrial ultrasonic cleaner operates at 25 kHz for coarse removal of lapping abrasives and polishing media, while the 45 kHz frequency is used for fine cleaning of oils and grease on metals and glass and hard precious stones.  My 35/130 kHz unit operates at 35 kHz for hard surfaces and at 130 kHz when I am cleaning sensitive pieces such as delicate jewelry and electronic parts.

Degassing and Sweeping Functions for Further Economies

All Transsonic TI-H ultrasonic cleaners employ a degassing function for faster start-up after refilling the tank with fresh cleaning solution. Newly prepared solutions contain air, which impedes the effectiveness of the cavitation process until it is removed.  The degassing step does this far more efficiently than starting ultrasonic cleaning with new solutions from the outset. 

The sweep function enhances cleaning uniformity and increases throughput.  The TI-H unit’s sweep function continuously shifts the ultrasonic frequency thereby creating a uniform sound field distribution throughout the bath.  This enables the cavitation process to efficiently reach all surfaces being cleaned eliminating so-called ‘dead zones’ in the tank where no cleaning occurs.

Additional features include a thermostat to set bath temperatures, heat and sound insulation for a friendlier working environment and an extra heavy-duty tank manufactured from cavitation resistant stainless steel for longer service life.

How many ultrasonic cleaners do you use?  What are they used for and what frequencies do you employ for these operations?
