How to Use Industrial Ultrasonic Cleaners for Heavy Parts Degreasing?
Heavy parts degreasing engines and other heavy, complex machinery components can be accomplished quickly and effectively by cavitation action in industrial ultrasonic cleaners. This post provides guidance on the benefits of ultrasonic cleaning, how to use an industrial ultrasonic cleaner, and how to get the best performance from your industrial ultrasonic cleaning equipment.
But first….
Why Use an Industrial Ultrasonic Cleaner?
Cleaning and degreasing heavy parts can be accomplished several ways. Commonly used options include high-pressure steam cleaning and degreasing, solvent-based wash tanks and high-pressure sprays.
Common disadvantages of these options in addition to being time-consuming is that they are unable to penetrate and remove grease and other contaminants lodged in cracks, crevices and blind holes found in complex-shaped industrial parts.
Yet another disadvantage is that solvent-based wash tanks and sprays may introduce environmental concerns both in terms of use and solvent disposal.
In contrast…

How to Use an Ultrasonic Cleaner in Your Hair Salon
Some states are adopting regulations requiring ultrasonic cleaning and sanitizing of tools used in hair salons and cosmetology salons. New Jersey, for example, requires a designated area for cleaning and disinfecting implements and tools, an ultrasonic cleaner for metal implements and tools, a clean, closed receptacle at each work station so soiled implements and tools can be completely immersed in an enzyme solution prior to cleaning and disinfection, and a clean, closed receptacle for storage of sanitized implements and tools at each work station.
Nothing surpasses an ultrasonic cleaner for removing dirt and contaminants from any equipment that can be safely immersed in water. Healthcare facilities have long relied on ultrasonic cleaners to remove blood and tissue from surgical instruments prior to disinfecting and sterilizing. A compact ultrasonic cleaner such as Elma’sE30H model available from Tovatech easily fits on a bench or tabletop in a designated cleaning area in a … Read the rest

Industrial ultrasonic cleaners come in many sizes, shapes and features. This guide will help you pick the equipment right for you.
What is an “Industrial” Ultrasonic Cleaner?
You might think an industrial ultrasonic cleaner must be “big” because it is handling industrial products. Not necessarily so. Your industrial parts washer size (or cleaning solution capacity) is governed by the size of parts you are cleaning. They are offered as benchtop and floor mounted models.
Another consideration to keep in mind is the duration of your cleaning cycles. Long-term cleaning cycles (i.e. operating continuously over a work shift) mean your unit should have a heavy-duty tank to prolong service life.
An example is the heavy-duty, Elma xtra TT series benchtop industrial ultrasonic cleaner with tank sizes from 0.79 to … Read the rest
