Keeps my laser operating at a constant safe temp. Not very nosey. Not very noticeable over the noise of the laser. Been using for two months and no problems.

Seller was great, got one of the last units available. Shipped quickly, and works great. Genuine Teyu S&A fiber chiller, the best.

This unit is regarded as one of the best. It is pretty much essential for laser systems as it increases laser machine life. Furthermore, the price here is outstanding. It is a genuine S&A brand unit, not a knock-off.The knock offs suck. S&A units are more reliable and are better made. They last longer too.

We have a very powerful Jewelry laser welder which had it's own cooling system, but, when we run it for 8 hrs non stop, the machine began to loose power and damaged . We added the cooling system directly on the machine and disconnected the built in cooler. Now , it runs all day with no issues.

This is the name brand S&A CWFL-12000 fiber chiller. It was shipped the same day I ordered it and arrived in 7 days. I use this chiller to cool my laser and it does a great job. I have not had any problems at all with this unit.

Since I invested in a 1000W laser cutter/engraver, I didn't think it was appropriate to skimp on a cooling system since it would directly affect the life and performance of the machine -- as wattage increased, so does the cost , dramatically. I opted for the CWFL-12000 50HZ 60HZ ​model and have not been disappointed. It came extremely well packaged. The installation and setup was very easy. I referred to a few YouTube videos for configuration, opting for the fixed temperature mode vs. the default smart mode --- I wanted to start by controlling the target chilling temperature myself. As for noise, there's some initial beeps during power-on start up, then the intermittent sounds of the compressor kicking in to control the chilling temperature, nothing unreasonably loud in a shop environment. Overall I have been very pleased and highly recommend purchasing genuine S&A products.
