1/3 HP Glycol Bath Chiller — 2200 BTU/hr @ 28°F ❄️

Fermentation temperature control + crash cooling for up to 4 fermenters
Proudly Built in the USA • Built-in Controller • 1-Year Warranty

If you want colder temps and tighter fermentation control than a standard water chiller can provide, this is the upgrade. Our glycol chiller is designed to maintain a cold glycol reservoir (set it, forget it), then deliver chilled glycol to your fermenters via submersible pumps—ideal for brewing and other low-temperature applications.

What it does (simple) ✅

• The built-in controller maintains your glycol reservoir at a setpoint (example: 28°F)

• Use one submersible pump per fermenter (recommended)

• Each pump is typically controlled by its own pump controller, so you can run different temps on different fermenters at the same time

Why brewers choose this chiller 🍻

Lower operating temps than water chillers

Suitable for applications down to about 5°F (depending on heat load), making it great for fermentation control and cold-side applications.

Run up to 4 fermenters

The reservoir lid includes 4 inlets + 4 outlets (3/8" barbed fittings), plus an additional pass-through hole for pump power cords.
(Note: product photo showing only 2 in/out barbs needs updating.)

Insulated glycol reservoir

Holds 5 quarts of glycol, helping the system stay cold and stable.

Glycol mix recommendations 🧪

You can use different water/glycol ratios depending on your target temperature and freeze protection. For brewing, it’s common to use 33–50% glycol.

• We recommend 50/50 for simplicity and extra freeze-protection buffer.

• In testing down to -14°F, a 50/50 mix performed without freezing issues.

Important brewing note ⚠️

This chiller is designed for maintaining fermentation temps and crash cooling.
It is not intended to chill wort directly from boiling temps.

Common practice:

• Use tap water first to drop wort to ~100°F, then switch to glycol, or

• Use a two-stage system (chiller pre-cools water that then cools wort)

Pro-level control without the fuss ✅

Set the glycol reservoir temp on the chiller, then let each fermenter controller manage its own pump. That’s how you get independent fermentation temperatures across multiple vessels—clean, scalable, and repeatable.
