As an industrial-grade ultrasonic cleaner, the Kendal model cd4820Plus includes a powerful transducer that can generate up to 42 kHz of ultrasound waves. This is more than enough to achieve a good-as-new effect on most jewelry and other metal tools. When used as a household item, the Kendal model cd4820Plus will encourage you to find other items at home to clean due to its efficiency. And when used in a commercial setting, your customers will thank you for the quick turnaround when cleaning their items.

Another advantage with the Kendal model cd4820Plus ultrasonic cleaner is its large capacity tank. It measures 9.6 inches in length, 5.9 inches in height, and 3.0 inches in thickness/depth. This area makes it suitable for cleaning longer items and multiple items at the same time.

The Kendal Ultrasonic Cleaner also includes a built-in heater. This is useful for removing stubborn dirt and grease from carburetors and other old tools. Sometimes hot water is also needed in combination with other cleaning solutions in order for them to work.

Another useful feature of the Kendal Ultrasonic Cleaner is the built-in radiator fan and circuit board protector combo. This prevents overheating and will protect your Kendal device from voltage surges. Some consumers tend to use their ultrasonic cleaning machines frequently and without allowing the machine to properly cool down in between uses, eventually leading to the device’s early demise. With a radiator fan and circuit protector, your unit is protected.


A minor gripe about the Kendal model cd4820Plus ultrasonic cleaner is that it only includes a plastic rack without handles. This makes it difficult to remove items from the cleaning tank, especially when the heater is turned on. As a workaround, you can get a separate wire mesh basket for the Kendal Ultrasonic Cleaner instead.

Another disadvantage of the Kendal model cd4820Plus ultrasonic cleaner is that its heater only allows increments of up to 8 minutes for each heating cycle. You cannot keep the unit in a preset temperature for more than that. Perhaps this is a precautionary measure to prevent overheating the device. But if you have items needing to be cleaned and soaked in high temperature for a prolonged period of time, you might want to look into other sonic cleaner models.
