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

Proud to introduce our In-House  LO Q600 Mini chiller.  This modular cooling system is our newest addition for our 2020 line-up, this product is designed by our engineers to provide you with an accurate, efficient, and reliable performance for water chiller during the most critical times. The Q600 mini water chiller is ideal for cooling low power laser tubes but comfortably can cool tubes with a rating up to a 90W.  For users using their tube at full operation, the performance is better for tubes rated under 80W. 

The LO-Q600 is equipped with the JLD612 temperature controller,  a very versatile controller that offers accurate, reliable temperature control. The PID parameters fine-tuning functionality will provide control for the Q600 refrigerant to keep the water temperature within the pre-set temperature range.

Running great for the last several months

Review by Robert on 5/27/2016

I am using this with a Chinese eBay 50W (actually 35-40W) laser and it works great. Easily keeps the water at the set point temperature. The instructions are a bit obscure, as there is no manual yet, only one for the competing CW5000, but it isn't that hard to figure out. A few notes: I found a puddle of coolant under the machine after about a week, but either the leak has stopped (unlikely) or perhaps I overfilled it? On a related note, I was surprised at how small the coolant reservoir is. Seems like only it only holds a quart or two of liquid? Regardless, it works well and never allows the water to heat up past the set point temperature, even after running the laser for 4-5 hours straight.

Working Good

Review by Reuben on 6/19/2016

As I started to cut for hours at a time throwing snow from the yard or ice from the freezer into the water bucket quickly became old. So I decided to upgrade to a chiller. I picked this chiller because of the price, it fit my 40w laser specs, and lightobject's good reputation. There is no instruction manual so I just run it as is. The default setting is 20C, or 68F. My work area heats up over the warmer months so when I fire my machine up the temp is about 79F and in about 30 seconds the water temp decreases and a few minutes later the temp is a solid 69F. The temp does swing back and forth during cutting about one degree. I think the lowest setting is 20C because I can change this up, just not down in temperature. The unit is not any louder than my laser, air assist, and exhaust. The barbs are 10mm, but I used 3/8" silicon tubing from the hardware store and was able to slip them over the barbs just fine. The water flow is surprisingly strong. Also there is a no flow alarm.

Works very well

Review by John P on 9/21/2016

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!!!

Working well, good product

Review by James Barber on 12/8/2016

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 Great!

Review by David on 5/4/2017

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!
