Only had a over a week...

Review by Patrick on 1/15/2021

Excellent shipping time and packaging. Works well during long cutting times- keeps the laser water at 61 degrees F for an hour. Fairly quiet, too! My laser is listed at 50w, probably more like 40w, so I am not sure how well it would work with something over 60w. The water level glass has a backlight! Easy to tell how much water is in it. Only complaint is that it starts the pump with such pressure that the second time I used it, the pressure popped the output hose off. I needed to get metal cooling tube clamps to hold the tubes on. So I suggest the clamps and to change the plastic hose fittings to brass barbed.

2020 Mini Chiller review

Review by Joe on 7/11/2020

I purchased the new 2020 mini chiller version for my 40watt machine. Shipping was a bit expensive. As far as the chiller it is well made and chilled my water to 18c in under 4 minutes and then shuts down into a low power chill mode which is very quiet. Overall I am very happy with the chiller so far.

Works pretty well, could use some improvements and better packaging

Review by Trevor on 4/27/2020

This is a fairly nice unit, but I do wish they would make some improvements. First of all the packing/shipping. 60 bucks to let UPS beat the piss out of this is just too much. I realize it is heavy but 60 seems steep. Mine arrived with a big dent and crease on one side where it had been dropped at some point. The box is lined with blue foam, but it is very rigid and does nor rebound so one shot from the carrier and it is crushed and cracked and no longer provided any protection. As for the foam, my chiller was literally covered by blue dust from the foam Inside and out. It would be nice if it was placed in a bag prior to boxing. As for the chiller itself it seems to be quite nicely made with good fit and finish overall and tidy wiring etc. The temp PID is very confusing, and the instructions dont help much. It comes preset to a range of 23-25 C And for 500 bucks I should not have to download and print the 3 page manual myself. It also needs casters!!!!

Running my laser non stop...

Review by Anthony on 10/25/2018

Before this I had a make shift cooler which extended my laser time, but never long enough to do real production work. Well worth the upgrade. I could laser cut enough in one day to have paid for the unit. I just ran for 5 hours straight yesterday cutting coasters and it maintained my machine well. It's been almost a year since purchase and I would recommend this unit for laser cooling. My machine is a 50W with a 1M tube. This should handle full production on a 60W tube which will be my next upgrade.

Great value for the price

Review by Niles on 3/20/2018

Great product for the price. Instructions are hard to read due to translation and lack of detail, AND are written for a different model. Luckily it’s pretty much plug and play. Chiller does not have a level meter so it’s a little hard to know the right fluid level. Packaging was excellent quality with sufficient padding and even with a hole in the box upon arrival due to shipper handling the chiller was unharmed. It comes with Teflon tape for the fluid fittings. No leaks. Haven’t tried altering the programming but seems intuitive enough.
