An Ultrasonic Cleaner for Growing Cleaning Businesses

Heater: Thermostatically adjustable heater.

Benefit: Improves cleaning effectiveness; required for removal of grease and oil.

Sweep frequency: Continuous slight variation of ultrasonic frequency to eliminate hot spots, dead zones, and standing waves. 

Benefit: Provides uniform and thorough cleaning.  Prevents damage to electronic components.

Safety auto-off: Ultrasonic power shuts off automatically after 12 hours of continuous operation. 

Benefit: Protects parts and prevents damage to machine if you forget to turn it off.

Drain: Drain with valve for easy removal of fluid from tank. 

Benefit:  Simplifies maintenance.

Degas Mode: Intermittent operation of ultrasonic power for rapid removal of entrained air from liquids.

If your ultrasonic machine business is growing you may be ready to move up to the 7.5-gallon capacity S300H ultrasonic machine with its multiple 37 kHz transducers for powerful and fast cavitation action. With internal tank dimensions just under 20 x 12 x 8 inches deep, this ultrasonic water bath sonicator is sized right for heavy-duty degreasing and removing chips, fines and polishing powders from machined, fabricated and cast parts prior to subsequent processing.

Putting the S300H ultrasonic machine to work

Remember that all freshly prepared biodegradable ultrasonic cleaning solutions must be degassed prior to the cleaning process. Activate the auto-degas mode on the S300H to accomplish this in 10 minutes. In the meantime place the workload into the mesh basket (available separately).

Set the cleaning time and cleaning temperature. The unit will start when the set temperature is reached. Activate the sweep function for even distribution of sonic energy throughout the bath. Lower the workload into the solution and cover it to reduced noise and conserve heat. The unit will stop at the end of the cleaning cycle. Remove, rinse and inspect products prior to further processing.

Skim off oils and other substances that rise to the surface and set them aside for proper disposal. When the cleaning time lengthens, drain the tank and dispose of the spent solution and skimmings according to local regulations. Clean the tank following manufacturer’s recommendations before refilling it with fresh solution.
