Recommended Glycol Mix:
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.
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
Manufacturer Guidelines:
- 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.
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.
Setup for Brewing Applications:
There are 2 main ways to accomplish this, and our chillers can be used with either method:
1. 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.
2. 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. (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.
