• Sound Rating: 59 dBA
• Power Cord: 6′ Power Cord
• Built-In Controller: Monitors and maintains the glycol reservoir at your desired set temperature.
• Fittings Included: 16 qty double sided 3/8″ barbed fittings to allow tubing to run through the lid (accounts for 8 outlets and 8 inlets).
• Additional Lid Openings: 8 openings in the lid to pass the power cord of submersible glycol pumps through.

• Pumps not included. Cold glycol can be pumped out to cool a piece of equipment, or the reservoir can be used as a bath for laboratory type applications.
• Brewing sizing varies by setup. See the Brewing Sizing Guide and comparison chart below.
• For exact model-to-model differences, see the comparison chart for the selected size.

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 suggestions in the chart assume the fermenter is insulated with a neoprene jacket or better and ambient conditions are roughly 80°F. If you will be operating in hotter 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 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 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, 2x 10gal 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.

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

• 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

With the controller on the chiller set to 28°F, 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, and our chillers can be used with either method:

• 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.

• 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. (Contact support for more information)
• 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 accessories needed to setup a glycol loop.

• Most of the information on this page is tailored to brewing applications, but any application needing cold temperatures can utilize our glycol chillers.
• 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 ways to have a chiller assist in the knockout process, but it typically involves a 2-stage cooling process.
• NOTE: The glycol returning to the chiller should never be allowed to reach more than 100°F.
• Use the proper glycol/water mixture for your desired operating temperature and application.
