All good things must end, and no matter how good your ultrasonic cleaner is, you’ll eventually have to replace it. The good news? If you’re careful about your choices, you can end up with a unit that’s a vast improvement. Here are four things to look for when you’re choosing a replacement ultrasonic cleaner:
A WARRANTY THAT INSPIRES CONFIDENCE
Nothing tells you a product is dependable and well-made like a strong warranty. Your new cleaner should have a warranty that’s lengthy, but length shouldn’t be your only consideration. Be sure to check what components are included or excluded and whether some have shorter coverage than the main warranty. Be sure your warranty begins on the date the cleaner is shipped or delivered, not the date it’s manufactured. A warranty agreement that goes into effect months before you even order your ultrasonic cleaner is not much use.
If you’d like more detail on this subject, we’ve prepared a handy list of questions and concerns to consider in regard to these warranties.
A “MADE IN THE USA” LABEL THAT MEANS WHAT IT SAYS
Many US-based ultrasonic manufacturers source their components and materials from outside the US. Since you may be reading this on a phone made in South Korea or running a facility that assembles foreign-sourced parts into new products, that may not seem like a very big deal. But red tape, language differences, increased transit times, differing standards and time zones can affect everything from the quality of your cleaner to the quality of service the manufacturer provides after the sale. Make sure the company making your cleaner has control over every aspect of the process and can ensure a consistent and high level of quality.
A CLEANER WITH MULTI-FREQUENCY CAPABILITY
Different ultrasonic frequencies can deliver a diverse range of capabilities, but a transducer that produces a single frequency at a time can carry with it a number of problems and inefficiencies. For example, a single-frequency setup can produce standing wave patterns that lead to incomplete cleaning on some areas of a part, and the transducer diaphragms tend to erode much more quickly.
Transducers such as our Vibra-Bar® units transmit across a spectrum of frequencies above and below the main frequency—typically 40 kHz—all at the same time. This Simultaneous Multi-Frequency® technology improves cleaning, increases durability and provides a number of other benefits.
A CONTROL SYSTEM THAT WORKS THE WAY YOU DO
If the mobile and digital revolution is changing the way your team works and the way you interact with customers and suppliers, why shouldn’t it make your ultrasonic cleaner easier to use and more effective? An ultrasonic cleaner should include controls that work with mobile technologies to provide information and receive instructions.
We’ve introduced the Sonic Touch®II multifunctional digital control panel to deliver that capability. It can be controlled or monitored with an Android or iOS smart phone or tablet, and can be set up to run the ultrasonic cleaner with a countdown timer or a seven day schedule. The unit monitors cavitation activity levels using a patented Liquid Condition Sensor, and can notify supervisors of changes in system status through multiple methods. The Sonic Touch®II can give notice of scheduled maintenance or alert the user of a problem by sending emails or text messages to an appropriate account. It can also continuously record system data in real time, and download that data to flash drives.
There’s a lot to consider when making a purchase as important as an ultrasonic cleaner, but if you begin with those that are made here in America, have a rock-solid warranty, include multi-frequency technology capability and integrate mobile-friendly technology, you’ll be ahead of the game.
