Our glycol chillers are most commonly used for brewing applications, most of the information presented below is curtailed to brewing applications. However any application needing cold temperatures can utilize our glycol chillers. The chiller has a built-in controller to monitor and maintain the glycol reservoir at your desired set temperature. The cold glycol can then be pumped out (pumps not included) to cool a piece of equipment, or the reservoir can be used as a bath for laboratory type of applications. We provide 8qty double sided 3/8″ barbed fitting to allow tubing to run through the lid, this accounts for 4 outlets and 4 inlets. There are an additional 4 openings in the lid to pass the power cord of our submersible glycol pumps through.

While our chillers are perfect for maintaining fermentation temperatures and crash cooling, they should not be used to attempt to directly drop wort from boiling temperatures. There are a few ways to have a chiller assist in the knockout process, it typically involves a 2 stage cooling process. NOTE: the glycol returning to the chiller should never be allowed to reach more than 100° Fahrenheit.

Sizing a Glycol Chiller for Brewing:

To size a chiller you need to determine what’s the worst case scenario when it comes to how much cooling you’ll need. While you could size a chiller to be able to cold crash all of your tanks at the same time, that’s not how a typical brewery operates. 95%+ of our customers would be covered using our general rule of thumb for sizing (below the chart).  The suggestions in the chart assume the fermenter is insulated with a neoprene jacket or better and ambient conditions are roughly 80F. If you will be operating in hotter or conditions or without an insulated tank use the suggestion from the next sized up tank

Note: For the purposes of the chart “cold crashing” is only referring to the +/- 18hr period of active temperature drop. Once at a cold temperature use the “maintain cold” column for holding at cold temps to carbonate/clarify/etc. It’s common for the industry to refer to any part of the cold process as the cold crash, but for chiller sizing there is a significant difference between dropping the temperature and holding cold temperatures.

For tanks over 1BBL  we recommend an appropriately sized chiller from our our XL Glycol Chiller line

 

We typically break down a setup into a block of 4 tanks. Tank #1 is cold crashing, Tank #2 is maintaining cold, Tanks #3&#4 are fermenting. If there are a mix of tank sizes, the biggest is the tank is the one cold crashing, and the next biggest is the one maintaining cold.

If you have more than 4 tanks, the cycle repeats. Tank #5 is cold crashing, Tank #6 is maintaining cold, tanks #7&#8 are fermenting. If there are a mix of tank sizes you first fill “cold crashing” spots from both blocks with the biggest and 2nd biggest tanks, then fill the “maintaining cold” spots with the next biggest tanks.

Tank#1 – Cold crash

Tank#2 – Maintaining Cold

Tank#3 – Fermenting

Tank#4 – Fermenting

Tank#5 – Cold Crash

Tank#6 – Maintaining Cold

Tank#7 – Fermenting

Tank#8 – Fermenting

 

Example: 1x 1BBL, 1x 15gal, 2x10gal tanks:

Tank#1 – 1BBL Cold crash = 1,500 BTU/hr

Tank#2 – 15gal Maintaining Cold = 850 BTU/hr

Tank#3 – 10gal Fermenting = 70 BTU/hr

Tank#4 – 10gal Fermenting = 70 BTU/hr

 

In this scenario the BTU/hr adds up to 2,490 BTU/hr, you can then use this number to select an appropriately sized chiller that provides at least this many BTU/hr.


Recommended Glycol Mix

We recommend using a 35-40% glycol to 60-65% water mix for our brewing customers operating at approximately 28F. Other application may require a different mix depending on desired operating temperature.

Easy mix suggestions:

1 Gallon of Glycol + 1.5 Gallon of Water = 40% Glycol Mix

1 Gallon of Glycol + 1.75 Gallon of Water = 36.3% Glycol Mix


Setup for Brewing Applications

With the controller on the the chiller set to 28F, you need a way to regulate the flow of cold glycol out of the chiller to each fermenter so that a variety of temperatures can be maintained across multiple fermenters. There are 2 main ways to accomplish this, our chillers can be used with either method.

  • One pump per fermenter: A submersible glycol pump is put into the reservoir, tubing is run out to a single fermenter and back to the chiller. The pump is plugged into a controller that monitors fermenter temperature. The flow of cold glycol is regulated via the pump turning on/off as needed for that fermenter. We sell this style of pump/tubing/controller – see our glycol chiller accessory package.
  • Glycol Loop: A single external continuous duty pump runs 24/7 to provide flow through a network of pipe in the brewery. There are solenoid valves on the supply line that are wired into a centralized control panel for the entire operation. The flow of glycol is regulated via opening/closing of the solenoids to provide glycol to a particular fermenter as needed. While our chiller will work for this type of install, we do not carry any of the products needed to setup a glycol loop.

    Just finished cold crashing my first brew using the Penguin 1/3 HP Chiller. I can say the chiller is amazing and dropped the temperature of a 5.5 gallon batch in a CF10 Spike conical from 70 to 36 degrees in just under 4 hours. The chiller is quiet and cools the glycol tank very quickly. I am very happy with this purchase and the team at Penguin were awesome to work with. Thanks for a great American made product! I hope to be cold crashing my next batch soon!

  2. Victor (verified owner)

    First off, the 1/3 HP GC is reasonably priced. I purchased it w/ the extended warranty to be on the safe side. The instructions are easy to follow. I assembled my FTSs2 onto both SS BrewTech Chronical Fermenters. I threw tubing as instructed, and added the Ss BrewTech Neoprene sleeve to prevent condensation from taking place as I will be cold crashing between 35-38F both fermenters simultaneously, and will be chilling worts down to 68F for fermentation. I went w/ the 50/50 glycol-to-distilled water recommended mix, plugged it in, and set the chiller temp to 28F. It went down from 77F to 28F in just under 10 minutes! I did a test run w/ water on both fermenters, and set both temps down to 65F. After the 5 minute delayed protection (factory setting w/ Ss BrewTech), both systems turned on and chilled the water down to the aforementioned goal temps in under 15 minutes. As for now, I’m amazed and super content w/ my purchase of the Penguin 1/3 HP GC. Brew day is this coming weekend, and I’m sure it’ll be successful. Oh, before I forget. The GC is not loud at all!

    Prost!

    Received my chiller last night after trying the refrigerator with ice water method and failed miserably… This chiller did awesome!! I put 115 degree water into the fermenter and it cooled it down to 34 degrees in no time! I ferment in a CF5 in the garage so this worked great!!!

  4. Jacob

    I’ve had this chiller nearly 2 years, and it has easily kept 40+ batches of beer cool while fermenting with cold crashing at the end. I have two 5 gallon Spike conicals in a 70 degree basement, and it can easily cold crash both at the same time without any temperature rise in the glycol reservoir. I would imagine it would have no problem keeping up with four fermenters as advertised even in hotter conditions.
    I did have an issue with the glycol reservoir cracking and causing some leaking after the warranty was expired. When I contacted Penguin, my issue was handled promptly with Penguin paying to have it packaged, shipped, repaired, and returned to me. Eric the owner worked with me directly and is clearly very invested in ensuring that his company is producing and standing behind a quality product.

  5. Mitchell

    I’ve had the chiller now for about a month and it’s been working great! We will see how things end up over time, but one thing I wanted to rate highly is the customer service. Raelyn was very fast and helpful in responding to my questions regarding maintenance of the unit. So far, this company is one that I am happy to have done business with. Thank you!

  6. Marc (verified owner)

    I’ve owned the 1/3HP chiller for 18 months now and it has exceeded my expectations. It is quiet, compact, and easily cold crashed three Spike Flex+ 7gal fermenters to 34F for a full week in 80+ degree heat. I expect to add a fourth fermenter and have no doubt that this chiller will be able to support it. Thanks for the great product!

  7. Matt

    I’ve had the 1/3 chiller for about a year now. Amazing product. I use it to chill a spike flex plus and it’s easy to maintain and operate. Not only a great product, but the customer service is amazing. I’ve had numerous questions that I’ve emailed over and got quick responses with detailed answers. Thanks for a great product and service.

  8. Rodney McAdams

    Owned the 1/3 chiller for a couple of years and use it to condition my brews in the two 1/2 barrel Spike conicals that I own. During my purchase decision I was worried that the 1/3 Hp model would struggle when my brew shed (OK, my garage) would be 95F in the summer and I needed to maintain lager temperatures or cold crash my beer. The information on this web site indicated that it would, so I pulled the trigger and bought it.
    The 1/3 chiller performs beyond my expectation and needs. It is reasonably quiet and easily handles my two conicals in any condition or combination. I rarely endorse products, but this product is deserving of a great review as it is worth every dollar spent on it.
