Item Description

Now with freeze protection, helps prevent freezes in the event of a pump failure (Photo shows previous version, new photos coming soon.  Inlet /outlet are now on either side of the controller)

Penguin Chillers are constructed using high grade materials to quickly and efficiently chill liquids.  We design our chillers with oversized titanium coils, the extra surface area allows for faster and more efficient cooling, and titanium stands up to the harshest of corrosive environments without leaching.  Yet our chillers typically cost less because you are buying direct from the manufacturer.

Applications include:

  • Marine / Reef Tanks
  • Bait Tanks
  • Lobster Tanks
  • Hydroponics
  • Aquaponics
  • Cold Therapy Tubs
  • Electroplating
  • Computers
  • Printing Presses
  • Injection Molding
  • Food Production
  • Lasers
  • Research Science

  1. Matt

    I previously purchased a hydrofsrm active aqua 1/4 hp chiller, which was not only unable to handle the required gph pump for my system, but failed to cool effectively and had issues blowing fuses. I returned it and ordered this, and wow. Water temps down from 78 degrees to a nice 68 degrees, easy to setup and install. Unit is also less obtrusive, and runs quietly. Best purchase i could’ve made for my garden, I will recommend this to anyone that will listen!

  2. Dan Bridgers

    I bout this item just over a year ago, and it has worked flawlessly! The unit cools quickly and quietly. I wont hesitate to buy one again when the time comes. Super quality and built to last, just can’t say enough good about it!

  3. Russell mark davis

    I have not purchased one yet but by looking at it i can tell its well made to last.i will be geting one soon

    I bought one of these for my DIY small scale recirculating system for hatching trout eggs and rearing them to four to five inches before releasing them into a flow through outdoor pond. Worked great! I was able to keep water temps in the low to middle 50’s F. from an ambient temperature in my basement of the low to upper 60’s.

    I’m getting ready to run it again for another few months of my second hatch of trout eggs.

    The price also much was better than a lot of chillers out there I was looking at. Unfortunately I’m not sure what size it is (hp) as I can’t find that on the model anywhere.

    Great chiller!! I’ve used a few other brands over the years and the penguin is by far the best I’ve used. No problem keepin 150 gallons @ 66 degrees in 90 degree ambient, and still cycle. Very impressed.

    The glycol chiller has performed flawlessly for about a year. The price was very reasonable and the response to a minor issue was promptly handled by the folks at Penguin Chillers. I would highly recommend their products to anyone looking to up their beer making process.

  7. Phillip Boles (verified owner)

    I’ve been using the 1/2 hp for around a year now on my man cave 125 gallon fish tank. Water was mid 90s now I keep upper 70s and the machine runs about 2 min every 30 min or so and decently quiet about like a fan kicking on. No problems with it yet and so much more affordable than any other brand with comparable strength.
