Low-Temperature Glycol Chillers
In an industry where temperature control is critical to the quality of final products, you can depend on glycol chillers from Cold Shot Chillers®.
Great quality beer is dependent on a variety of factors, the most critical of which is the flavor. The taste of beer is affected greatly by its temperature at fermentation. Keeping the taste of beer consistent keeps customers delighted and committed to your brand, and this can be achieved by maintaining ideal process temperatures inside the brewer during production.
The most effective way to maintain stable process temperatures inside a brewing unit is to utilize brewery chillers, which are typically glycol chillers.
What Is a Glycol Chiller?
Brewery glycol chillers are cooling units that utilize propylene glycol (an organic anti-freeze agent) or a mix of propylene glycol and water to extract excess heat from a brewing process and dissipate it in a heat exchanger or refrigeration system. Brewery glycol chillers provide the close temperature tolerance necessary to produce final products of the highest quality.
Applications for Chillers in Breweries
Glycol chillers are suitable for specific chilling applications within the brewery industry. Some typical examples include:
- Brite tanks
- Two-stage heat exchangers
- Brewing Counterflow Chiller
- Nano Brewery Chiller
- Brew House Chiller
How Do Glycol Chillers Work?
A glycol chiller for brewery systems circulates supercooled glycol around a closed circuit. This closed loop is comprised of tubing that connects to the input and output sections of the chiller unit, and the heat exchanger. To cool wort, the glycol then circulates through the heat exchanger, cooling the vessel.
Propylene glycol has a freezing point of -74.2 °F (-59 °C) while a mixture of propylene glycol and water will maintain a more moderate freezing point. Thus, a water/glycol brewery chilling system can cool wort much faster than a water-only chiller without producing harmful ice in the insides of the brewing vessel.
For the most efficient cooling, many companies use a water/glycol mix of about 67% to 33% in industrial glycol chillers.
Brewery Chiller Sizing
With a broad range of chiller sizes, small breweries and craft breweries can benefit from efficient glycol chiller brewing. Use the free tools available on the Cold Shot Chillers website to make the most accurate brewery chiller sizing calculation today. We offer nano brewery chillers, microbrewery chillers, and more!
Brewing Temperature Control Is Critical to Brand Preservation
Several beer types have ideal wort fermentation temperatures for the highest quality brew. For example, the ideal temperature range for brewing ale is 68 - 72 °F (20 - 22 °C). Using a brewing temperature greater than this produces undesirable fermentation by-products that can be difficult to remove.
Conversely, brewing ale at a lower temperature can lead to incomplete fermentation. Both issues can cause the beer taste to vary widely, causing production inconsistencies and negative brand sentiment.
Trust Cold Shot Chillers® For All Your Brewery Chiller Needs
Our glycol chillers for beer brewing provide the close temperature tolerances required to produce a consistent quality and taste. Our brewing chillers are manufactured using the highest-grade materials to ensure long-lasting operation. We offer a range of low-temperature glycol chillers to suit any brewery size.
Cold Shot Chillers® beer chillers have built-in safety features that monitor and control the temperature of your brew at all times.
