This 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.

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.
