LightObject LO-600W Mini Water Chiller for CO2 Laser Machine or CNC Router (AC110V 60Hz)   

High efficiency and quality built water chiiler


Our LightObject LO-600W Mini chiller, with an AC compressor, is a REAL chiller unlike the basic water pumps you can find on eBay that sell for up to $450. Those water pumps don't have an AC compressor so they only circulate the water, no chill it.  The LO-600W is ideal for laser tubes with power rating ranging from 20W to 60W operating full time and 80W laser tubes operating part time.


The LO-600W has a durable, compact design - and a great price!

Not awesome - quality components but poor assembly and QC
So no manual, but it's pretty self explanatory. Hooked it up, filled with distilled H2O, turned it on, worked great for about 3 minutes before I noticed the rapidly expanding puddle under the unit. I quickly disconnected it, plugged the hoses and ran the unit outside, where I tried to open the drain plug, but could not, because the cap was on tight but the port was not secured to the frame so it would just spin, twisting the silicone hose attached on the inside. Great... So my choices were send it back for replacement and be without a cooler for probably 7-10 days, or crack the case and see what the problem was (probably voiding the warranty) and fix it myself. It couldn't have been a simple hose had split or come off, water was pouring out around the temp sensor in the port at the bottom of the tank. What looked like white marshmallow spread that had been gooped around the sensor to waterproof the port was just disintegrating and falling off. I fixed it myself and now it works fine. Reply by LO: Hello, sorry for the trouble. FYI, we tested all our chillers before shipped. It looks like that it was a terrible job done by the FedEx carrier. BTW, we do have manual available through our Support Forum site. See

My First
I am a refrigeration service guy did commercial work for over 25 years and I was impressed by the quality. How did I see the inside? When it came the UPS people forgot about the This Side UP label and it was laying on its side and when it would not power up, I removed a cover and had to replace a loose wire. Did let it set 24 hours right side up before using. Filled with water, hooked it up and turned on, works fine and I did no adjustments! The price was right and it worked, thanks LO folks!

Works Great!
After doing the water in a 5-gallon bucket thing with my laser for a while now, I decided it was time to get a chiller. It was shipped fast, easily installed and works great on a 40-watt laser. Where I would get inconsistent results when lasering with the bucket method, I get much more consistent results when keeping the water temp around 20C, and can run the laser much longer. Unit is relatively quiet and the fan runs only when the compressor kicks in. Also, the built-in water pump is strong enough to keep any bubbles moving out of the laser tube, something that my old aquarium pump in a bucket could not do - the tube would accumulate tiny bubbles as usage went on. Also, this unit required less than a gallon of distilled water to put me in business! For just a tiny bit more money than the passive chillers out there that can only get the water temp down to whatever room temperature is at best, you won't regret spending the extra for this active chiller. Recommended!

Working well, good product
I haven't had the LO600W in production long enough to give a full review, but so far I can tell you that it's well made and does exactly what I need. I currently have a "50W" tube in the machine (as advertised at least) but am upgrading to a "real" 60W and bought it to be able to run large job batches. So far, so good.

Works very well
Got my chiller a few days ago and absolutely love it! It keeps a proper temperature and with the display, I can watch the water temperature and there is a water level gauge right on the front of the unit. Setup was quick and the cooling tubes (8x12) fit very tightly. This makes my engravings much easier to produce and no more having to refrigerate a water bucket the day before a run. I can come in, turn it on, and let the light shine!!!
