    • It was definitely worth the investment and has made my cold plunge experience even better.
I was in need of a chiller for my 140-gallon cold plunge and, after some browsing and comparing, I decided on this one. I’m happy to say I’m not disappointed! I had no prior experience with chillers and wasn't sure how to set it up, but the instructions were clear, and it was easy to get going. The chiller runs as expected, keeping the tank cool and maintaining a steady 50 degrees. It operates for about 45 minutes twice a day to keep the temperature stable, and the cooling process is efficient. While it does make some noise for a few minutes when it's cooling down to the set temperature, I actually find it soothing—kind of like the comforting hum of the A/C kicking on in a hotel room while you're on vacation. The temperature is consistent and reliable, and overall, I’m really impressed with how well it works. It was definitely worth the investment and has made my cold plunge experience even better. ... show more

Review Image by AujSee AujSee
Had the chiller for about a month. I use it in my cold plunge 5 days a week. The system has a built in 2 degree dead band so if it’s set on 46 degrees the system won’t kick on again until the water reaches 48 degrees. That can be changed but it helps preserve the compressor life. I have it hooked up to a 90 gallon plunge and it works flawlessly so far. You’ll have to buy a separate pump. I included a picture of the online pump I use. It has 3 speed settings and has been a lot better than the pump the company suggests. The systems quiet and cools quickly. For the money I really don’t think you can find a better chiller. I actually found this on YouTube initially. A lot of guys were reviewing it so I figured I’d take a chance on it. ... show more

    • Do not buy
This product worked well for a little while. The temp is not calibrated any longer and is running about 50 degrees off. The company will not answer the phone or return my messages. I can’t find any replacement parts either. Very disappointed in that. This chiller was a lot of money to only work for a short time. Would not purchase again and do not recommend anyone else to purchase this pos. ... show more

    • Great chiller, budget friendly
This chiller really has saved my sanity when I was coming close to losing it. It's quiet except for compressing due to an auto-off feature. It's large, which is understandable, so placement is a consideration when placing. I had the smaller 1/10 HP hooked up to my 29g coldwater tank but it was a third the size it needed to be. That little thing hung in there for three years until I figured out how to properly measure a chiller and was only taken out by the freak heat wave earlier this year. The 1/4 HP is gorgeous for my 29g (requires a regular 10°F drop, 15°F in extremes). This brand is budget friendly and will do what you need if you get your calculations correctly ... show more

    • It Really Works
Works great. I bought this chiller for my Costco cold plunge along with the Danner 1200 pump. Was able to run tubing from the unit in my garage outside a window to my tub. I am in FL where it is 80-90 degrees and able to keep the plunge at 55 degrees continuously. It is relatively quiet. Very pleased ... show more

    • Great aquarium cooler!
Follow up June 2022: This chiller is still going strong. We've now upgraded to a 60 gallon tank and it cools it easily. Our original setup with a pump got dirty really quickly. We eventually upgraded to an HW-404B canister filter and put that in front of the chiller (the canister filter pushes water into the chiller). This greatly improved the cleanliness issue and we haven't had to clean the chiller pipes in over a year. This would be worth $500...it's probably the best chiller out there. If you buy this, I strongly suggest putting a canister filter in front of it to save yourself the trouble of cleaning it. Original review: We use this for chilling our axolotl tank in the summer heat of Texas. This thing is a beast! We only have it on a 20-gallon tank right now (Yes we bought one size too big) but it can take the temperature down from 20C to 16C in about 15 minutes. Our last cooler was a thermoelectric chiller and was constantly on, burning 120W. Though this chiller takes more power when it's turned on, it does not turn on very often and only stays on for a few minutes at a time. Our power bill is either lower or unchanged (really hard to tell) compared to the thermoelectric unit. We got this for about $300, so don't pay $500 or $600 for it. It seems to go on sale pretty frequently. The chiller is also pretty quiet, it sounds like a mini fridge when it turns on and the only noise is the fan. The only downside we've had is that this required some assembly to be useful in the tank. Definitely not an out of the box solution. We use this with a 550gph pump and a PVC spray bar we made which cuts down on the water flow in the tank (water currents stress axolotls). Our PVC intake that we made has a cylindrical sponge and I would recommend that anybody using this for an aquarium have at least one sponge filter on the intake. ... show more
