Customer Reviews for VEVOR 9L Tank Water Chiller CW-3000DG Thermolysis Industrial Water Chiller Water Cooling Chiller for 60W 80W CO2 Glass Laser Tube Cooler

Pumped chiller units are supplied by a small number of lab equipment manufacturers in Europe/USA. An item with a similar specification to this can be purchased for more than _5k and cheap options don't really exist outside the 2nd hand market (well in my student we once put a pipe coil inside an old freezer and pumped water through that, so there were some limited options). To my mind that price is much higher than the components required can justify but there were few other options. However, the arrival of items like this chiller make effective cooling affordable.The chiller came with a euro power lead and a fuse less adapter for a UK socket (I doubt that can legally be used in the UK) but it was easy to find a suitable replacement. It was shipped with some water still in the tank and had leaked a little, so the product was wet within the plastic wrap. After drying it off the product was none the worse for wear and functioned normally. It is simply but well constructed and functions very well, quickly dropping to a 4degreeC setpoint in our first test.You can't disable the pump so when switching on make sure a pipe is linking the input and output or drop the output pipe into the tank filler otherwise you'll have a fountain.It remains to be seen how reliable this chiller is but so far I am very pleased with it.

Kann nichts sagen, weil ich habe falsche Artikel bestellt

I bought this to use on an 80w laser tube conversion. The unit is very well made and the earth pin has continuity with the body of the unit which is not always the case with imported items. I filled mine with distilled water to prevent any limescale build up, you can see the level on the sight glass on the front. It has an audible flow alarm as well as cut out connections via a supplied plug on the rear. I connected these in to the flow cut off in my laser controller and it works faultlessly. The wiring diagram could be a little clearer but if you meter the connections out there are options for normally open and normally closed. All in I'm very happy with the quality, price and delivery on this unit. My unit was despatched from Germany but I was able to track it all the way.

It doesn't come with tubes, which was fine as I bought 2m length pieces. Massive reduction in temperature on my liquid cooled spindle (cnc). On the first run i ran it 24k rpms over 8 hrs and only reading a temperature of 29.8.Great addition to the set up

Ich verwende den CW-3000DG als K_lung f_ meinen K40 CO2 Laser.Das Ger?t ist sauber verarbeitet und funktioniert sehr gut.

Der K_ler l?uft sehr zuverl?ssig und wurde sehr schnell geliefert.

Il prodotto arrivato nei tempi previsti, ben imballato e al momento funziona perfettamente. Ottimo prezzo, peccato che seppur il venditore riporti partita iva italiana, non stato possibile farsi capire su come emettere una regolare fattura su partita iva italiana. pazienza.

Der Wasserk_ler wird f_ meinen CO2 Laser verwendet. Er k?nnte etwas leiser sein von der L_tung sonst funktioniert das Produkt sehr gut.

Good seller. ? Perfect chiller for my laser cutting machine. Use more 6 month. Thank you.

***Edit: I bought it at _139, and for that price it is a good buy and worth the money. The day after I wrote this review, the price jumped up to _399. I would not recommend it at this higher price, unless you really don't care about the cost.Original review...I have a (heavily modified) cheap Chinese K40 (40W) laser cutter. I used to have the standard setup of a reservoir of water and a fish pond pump. This setup worked OK-ish for small running times, but if I wanted to cut for more than 15 minutes or so, the water temperature would rise and the cutting efficiency would fall.Finally, I invested in this chiller. A little apprehensive at first as it is clearly another Chinese import; the manual is in less than straightforward English and the plug comes with a converter to allow you to plug it into a normal UK mains socket.Thankfully, you really don't need the manual, and the mains adapter is perfectly adequate.I didn't write a review until I'd actually used this for a few months.I'm now happy to say that I'm really, really pleased with it! It does exactly what it is supposed to.Today, I ran the cutter flat out for about an hour, and although the temperature did creep up a little (about 2C), that **might** have been affected by a fluctuations in the ambient room temperature, but even if not, it is markedly better than my previous cooling solution.For a 40W laser cutter, this is a good solution - I recommend it.
