Ultrasonic Buying Guide

Ultrasonic cleaning is proven to be one of the best forms of precision cleaning in industry.

With its many benefits including being environmentally friendly, has low running costs and is energy efficient.

Choosing the right ultrasonic is important to ensure you get the best cleaning results. There have been many examples of customers with machine that aren't the right power, right size or being used in the right way. Ultrasonic cleaning systems are a powerful precision cleaning tool but as with all things they must be used correctly. This guide gives you an indication of attributes and features you should consider when deciding on the best ultrasonic for you. It is only a guide and we would advise to get in touch for a Free consultation on what Ultrasonic solution would be the best for you.

Size

Does size matter? Are you struggling to know what size Ultrasonic cleaning tank you require? One of the most important aspects is the size of the tank. The size of the tank can determine a lot about what you will need ultrasonic power wise and also heating wise.  You must consider the largest component you will be cleaning, the amount of components you will be cleaning at a time and how you will be placing the components in the tank. EJ Electronics will provide consultancy to establish which tank will best fit the solution to your precision cleaning, 

Control

Power is nothing without control.....The level of control of an ultrasonic can vary between a simple to use analogue system to an advanced control digital driven systems. Some companies specify analogue control with big knobs to make the machine easy to use for an operator who is wearing gloves.

The amount control needed is dependant on the application and you can have different systems which give you control of time, heating , and the type of ultrasonics as well as many other features.  EJ electronics have mastered the art of variable powered ultrasonics that give you the right cleaning power for the right job so if you are cleaning something delicate today and something a bit more harsh tomorrow be sure that an EJ machine can satisfy all your needs. EJ Electronics can provide ultrasonic cleaning consultation using our expertise to help determine what will be your best method of control.

Transducer quality

What is a transducer and what does it do? The Ultrasonic transducer is what produces the sound waves in your tank and the quality of your transducer and how it is bonded to your tank are key components to effective cleaning. A poor quality transducer can damage the tank quicker and can fail without warning.  A poor quality transducer can also reduce the effect of cleaning. Many repairs we have in are due to poor quality transducers. EJ Electronics knowledge in Ultrasonic cleaning has enabled us to source test and develop not only the best transducer for  your tank but also a high grade aircraft specification bonding material to ensure that transducers are fixed in the correct position and wont fall off. Our transducers are proven to last longer than our competitors and with a better clearing action. This ensure that your machine is of high quality and lasting reliability

Ultrasonic Power

Will I have enough power? If you have been looking around for ultrasonic cleaning units for any period of time, You will have of had a lot of different figures thrown at you regarding power. There are many myths surrounding ultrasonic cleaning power and its measurement. The power for an ultrasonic cleaner is given by the generator within the unit. Some people will give you RMS output which is effective and some will give a peak output it is important when looking at Ultrasonic cleaning tanks to ensure you a measuring the like for like output of an ultrasonic cleaner.

To measure the power of Ultrasonic we use the watts to litre ratio. To gain effective ultrasonic cleaning you need approx. 7-10 watts per litre.

This ratio gives you the optimum cleaning power and is only an indication as variables such as temperature and the solution you clean in will be important factors to your cleaning action

EJ Electronics can provide consultancy which will give you an indication into the power you need by testing and trialing the component, your chemical and ultrasonic power.

Temperature

What temperature do I need for the best Ultrasonic clean? The temperature of the cleaning solution  is essential in some cleaning applications.  Some fluids require heat to ensure cleaning is effective where as other chemicals may have an adverse reaction to heat.In most circumstances your ultrasonic cleaning temperature should be between around 50 to 75 degrees similar to when you wash your dishes this gives a good cleaning action. However above 80°C can make ultrasonic cleaning  ineffective.  Having accurate temperature controls is essential to an ultrasonic and preventing the burn out of heaters keeps your machine going for longer. It can also be vital to have good heating so your operator isn't wasting time waiting for a cleaning system to heat before they start work. EJ provide a range of controllable heated options with safety cut out systems this ensures you have full control of your ultrasonic heating. Please contact us for a consultation if you would like to get the best heating options for your tank.

Timer

How long do I need to clean my component in an ultrasonic cleaning tank? That question can only really be answered by you, but being in control of your ultrasonic is important as you don’t want to be standing over your machine and waiting for it to finish the process. All EJ and Langford machines come with variable timers and the automated units have specific cycle programmes. EJ Electronics are happy to provide consultancy and trials to establish your cleaning times and ensure your tank is fit for purpose.

Basket

How will I mount my component in an ultrasonic cleaner? It is important when choosing an ultrasonic cleaning system  that you know how you will be placing the components to clean.  Some of the common reasons for tank wear and damage is users of ultrasonics leaving components on the bottom of an ultrasonic tank.  This is detrimental to a tank as the debris can literally shot blast the tank away and also reduce the efficieny of the unit. Customers should always use a basket or a jig to mount componets into an ultrasonic. During consultation EJ Electronic can help recommend the best way to mount your product in the ultrasonic cleaning tank.

Lid

A well constructed and fitting lid will aid with reducing  evaporation, help keep noise levels down and ensure the machine heats quick as possible 

Drain

Most uses of ultrasonic will require you change the fluid.  It is important to have a reliable drain system that prevents leaks but ensures drainage is easy.  EJ systems have manual stainless steel ball valves and automated drain systems also.

Sweep Technology

What is Sweep frequency?  Our advanced frequency eliminates  an old age problem where ultrasonics suffer from non effective parts of the tank.   This new system continuously sweeps the tank ensuring there are no dead spots or wasted area.  EJ systems give you effective cleaning throughout the tank

Chemical

Can I use a solvent in my Ultrasonic cleaner? What Chemical you use in your Ultrasonic cleaning tank is an important factor when purchasing a cleaner. Whether its water, a acid or alkaline based solution, a dangerous chemical you must consider what measures must be put in place to enable it to work with your Ultrasonic unit. . A  chemical can vastly improve the performance of an Ultrasonic cleaner or cause damage tank or a component. Some solvents have low flash points so must have extra safety measures and sometimes no heating at all. EJ Electronics will do a full consultation with you to ensure you are using the right chemical for your ultrasonic cleaner and its application.
