    water chiller

    Posted by Anthony D Hearne on Aug 11th 2023

    i was having an issue with inconsistency cutting with my laser cutter, turns out the water cooler that was supplied with the unit just couldn't cope. so i bought the Q600 water chiller to see if that helped, IT DOES, i can cut all day without fear of overheating my laser and i get consistent results, very pleased with my purchase

    Q600W mini Water chiller

    Posted by Mark Osgood on Apr 23rd 2022

    Worked great right out of the box. Just had to add a gallon of distilled water and solder the water warning plug.

    Great unit at a great price, service after the sale was phenomenal, the instructions do not explain how to wire up the alarm output, a quick message to Marco and the problem was solved. thank again for a GREAT product.

    Only had a over a week...

    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.1/15/2021 REPLY:Thank you for the feedback. If you do not have metal clamp handy, you may use ziptie to secure the water tube. Brass fitting can rust; that is one reason it has plastic fitting.

    2020 Mini Chiller review

    Posted by Joe on Feb 11th 2021

    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.7/11/2020

    Works pretty well, could use some improvements and better packaging

    Posted by Trevor on Feb 11th 2021

    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!!!!4/27/2020
