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

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.

Fan is extremely loud and I believe its not supposed to run 24-7

I like how you can adjust the heat, adjust the ultrasonic level, the timer, the degas mode. I put it to the test right out of the box on some real dirty sockets I got from a neighbor's garage sale. He could not believe how clean those Snap-on sockets looked afterwards.

Works well, heater gets very hot. Better if it came with a drain hose attachment.

So far I've used this a couple of times with extreme simple green and have had nothing but positive results. The pistons in the picture were all removed from the same engine. They were not scrubbed prior or after. Just placed in at 150 degrees and ran for 20 min then dried. They came out looking like new even with 80,000 miles on them. I've also cleaned motorcycle carbs other oil and fuel embedded items with positive results. Also threw in an old rusted wrench. It cleaned it but most of the rust is still there. Would buy again.
