CREWORKS 15L Digital Ultrasonic Cleaning Machine with Degas and Gentle Mode, 360W Ultrasonic Cleaner with Heater and Timer, 40kHz Ultrasound Cleaner for Industrial Parts Carburetor Auto Tool

I have gone through a few small, budget priced ultrasonic cleaners in my shop. They usually work OK. Temperature control is always iffy, there is often no facility to degas cleaning solutions and cleaning action isn't great. Eventually the heating elements go or the transducers go.The CREWORKS 6L Digital Ultrasonic Cleaning Machine is impressive for a number of reasons.The unit has three transducers which is on the upper end of transducer count for a 6 liter unit.The machine has a degassing function that can be used throughout the cleaning process, cycling between degas and clean, or for time of operator choice.The Creworks has excellent temperature control. There is a solution temperature rise above ambient with heat turned off, but this is normal for ultrasonic cleaning and caused by process cavitation. As an example, solution temperature rose from 61°F to 68°F during a full power, 30 minute cleaning cycle.The 6 liter size is handy. Usually they are too small to fit all of the machine pieces I work with, or too large and waste solution. This one is right for me, particularly with this tank's capacity and aspect ratio.The unit is well made. nicely finished and it definitely improves the appearance of my work bench.Of greatest importance, it cleans parts really well, and it does so quickly; light oxidation, waxy grease, general crud. The ultrasonic process gets into every surface. I'm very happy with the Creworks machine.

I've been using this unit for about 2 months now and I'm super happy with the results. Heats reasonably quickly and does an amazing job of removing grease and dirt from carburetors and other parts. If a part is very dirty I prefer to use my regular solvent wash tank to get the worse of it. Then I degrease in this tank and watch the solvent and remaining dirt/grease disappear. The action literally causes oil and grease to explode away from the part. It's amazing to watch.I bought this excellent unit after having significant hassles with a different brand that rimes with DeeVOR. Their customer service was awful and I had to fight with them for a refund of their defective product that lasted less than 5 minutes.

Works so well i spend more time cleaning the machine and cleaning parts in it very satisfied with the quality of the product

On my second tank after the first one had a mechanical failure on the power switch. The new replacement I bought now is starting to fall apart. Audible loud noises while the power is on (ultrasonic is turned off, heater is turned off), so im just waiting for this one to die on me.They work well for a couple of weeks, but if you are looking for something to actually use for more than a couple of months I would NOT buy this product.Really with there was a warranty or something I could do to get a replacement since I have bought 2 of these.

It seems like all of these overshoot their set temps which is why I returned a different brand for this one. I then come to find out that it has been a reported issue and I think people are over cooking these machines which can ruin Items you put in by taking off coatings or paint and making the machine have a short life.This Creworks is no different. I find that you need to understand it by monitoring the temps using a cooking thermometer and managing an offset. The temp display on the machine is accurate without the vibration but it is not once its on and doing the ultrasonic cleaning for reasons I cant explain but it shows it to be at least 12-15F degrees cooler than it actually is. In addition to this the ultrasonic action also increases heat over time which can change the offset you set.The best way I found to control temps is to set the temp you want before you turn on the ultrasonic function. Say you want cleaning at around 135F, set it at 132F. Once the set temps are reached set the offset at 118F for the heater to kick on or what ever offset works for you to keep the temps stable at 132F when the ultrasonic function is on. Over time the temps will rise to 135F as you monitor it externally using a cooking thermometer because the ultrasonic action will increase the heat for your 30 minute cycle due to the heat dissipation of the transducers. Once 30 minutes is expired and it stops vibrating you will see the temp on the display rise from 118F to 135F which is the actual temp. Most important follow the manual and let the machine cool down for 15 minutes before another cycle.Reading a lot of these reviews is depressing but I have a feeling that these machines are getting much hotter than the actual temp with most users unaware and with heat it creates malfunctions with the electronics which go bad.What is junk for some is an opportunity to get the most out of a unit like this at its price point with some awareness and a work around. Im at least happy that it has a 1 year warranty compared to others with a US contact.Everything is working great so far and the cleaning is exceptional but I am giving it four stars because the manufactures of these cheap machines should have found a better way to regulate temps or at least mention it. There is a video review where they mention that thermostatic control does not work which is wrong, it does work great as long as you set the offsets while the machine is running otherwise it will be too hot which gives you the impression that the heater relay does not turn off.

The item arrived well packaged, and was significantly protected from damage.I have put a few things to clean through it and have been overall satisfied with it's performance. It cleans well and the gentle function comes in handy with delicate items. It is well constructed and the finish on it is really amazing. It is loud, but every ultrasonic cleaner is, but is bearable if it is in the garage or another room. The extended timer is really handy but the manual says to limit to 30 minutes cycle. I haven't been able to figure out any way to change the temperature reading from F to C. For the price it is well worth it, but in my opinion, I would definitely try and get a size bigger than you think, you would think that maybe a 3L version is enough for your needs, but once you have a ultrasonic cleaner you will find bigger things to clean with it. Overall I am pretty satisfied with it, specially for the price, it works well and cleans well.
