Penguin Chillers 1/2 HP Water Chiller

The Penguin Chillers 1/2 HP Water Chiller is designed to keep your ice bath chilled at the perfect temperature with precision and reliability. With a cooling power of 5,000 BTU/hr, your cold plunge will be able to maintain temperatures as low as 37 °F even in the summer heat.

With dimensions of 16.25”W x 14.75”D x 12”H and weighing in at 39 pounds, this chiller is designed to fit seamlessly into your cold plunge setup without taking up unnecessary space. This chiller features 1" NPT inlet/outlet ports, offering convenient connectivity to a tub of your choice.

Operating the chiller is incredibly easy. Plug it in using its 6-foot power cord, and it will run efficiently on 110-120 volts, drawing only 3.9 amps and consuming a mere 450 watts. Furthermore, you won't be bothered by excessive noise since its operational sound level is very silent at only 56 dBA.

The Penguin Chillers 1/2 HP Water Chiller is proudly made in the USA and comes with a 1-year product warranty, with additional extended warranty options available. The 1/2 HP Chiller is great for those looking for a premium quality cold plunge chiller at an affordable price.

This Chiller can be used as part of a DIY cold plunge setup, which also requires a pump, tubing, and filters. We recommend the Danner Mag-drive pump with a flow rate ranging from 950gph to 1800gph. Check out our Water Chiller Accessory Package for more details. Pretty much any highly-rated 10-inch filter housing + 50 micron filters will be perfect for filtering your water.

If you have alternative pumps in mind, particularly those rated in horsepower, don't hesitate to reach out to our technical support. We're always eager to guide you in ensuring that our chiller is compatible with your system. And for optimal control over water temperature, our digital controller consistently monitors the incoming water temperature. If the temperature goes above the set point, the chiller activates, and once the desired temperature is achieved, it turns off, ensuring energy efficiency.

Amazing unit!

I switched from an active aqua quarter horsepower to this penguin half horsepower. I run 100 gallon stock tank cold plunge and it dropped 12° in 1 hour! This unit is an absolute tank!

Daniel Castro
Great chiller!

I bought this for my cold plunge tub. I live in Miami and was able to easily set this up on my balcony and it keeps up even with the warmer weather. My tub stays at a frigid 39 degrees. I’ve loved this product so far! Def worth the price!

Cold plunging on a balcony - that's dedication!

Alexander Makowski
Penguin 1/2 Chiller

I was expecting a 4-6 week delivery time because I know a lot of niche things that are almost industrial like this have a little lead time. My gosh the delivery took 6 days. I got it all hooked up and set up. A little leaky but that's some tinkering I need to work on myself. The chiller is easy to navigate. And with the pump it's a constant jet coming into my ice pod. I set it all up and did my first plunge today after taking off the last 3 months (I had free access to ice for 6 months) my gosh. 52 was a wake up call absolutely miserable, painful. Teeth chattering. But overall I felt amazing after. Wonderful product as of now. It's set up in my garage which is a little warmer than outside colder than inside. We'll see how well it maintains temps in the summer in that climate

I'm glad we were able to surpass your expectations! Definitely should be able to maintain temperature in the summer.

1/2 HP chiller

Service and timing was great. I worked through text to review a change(on my side) and it was seamless. Got my chiller in 6 days during the Thanksgiving holiday

We're always happy to help at any stage of the ordering process!

Logan Klaers
Cold as ****

I was nervous about whether this chiller unit would be able to maintain a sub 40 degree Fahrenheit temperature in my 100 gallon cold plunge. Worry not my crazy friends, this thing is a beast.

It has nice customization options for time delays between cycles, which saves on energy. The unit is quiet enough that you don’t notice it running if it is in the next room with the door closed, I have mine installed in my laundry room next to my office.

I’m ordering a second one for my father, so yeah 5 stars.

Glad to hear the chiller has lived up to your expectations!

Kyle Naismith
A "Cool" Addition to my Cold Therapy Practice

I paired this unit up to a Danner pump and 20-micron filtration system. So far I am really enjoying it and it has made my cold plunge practice much more sustainable and user friendly. I do NOT miss being reliant on bags/blocks of ice.

RIP ice bags!

Justin Canfield
Works as advertised

Hooked up the 1/2 HP chiller to my 150 gal. cold plunge. Keeps the water a crisp 40 degrees.

Awesome, thanks for the review!
