As we know glycol is very important for glycol chiller liquid. The major function of using glycol is to prevent freezing of the process fluid and ensure consistent flow at the operating temperature for glycol chiller normal working process.
As a leading manufacturer of glycol chiller, TopChiller has a complete glycol chiller line.
These glycol chillers are widely used in many industrial applications, like fermentation process in cooling the wort, controlling fermentation crash, cooling vessels and prepackaging in breweries and beers.
Other glycol chiller applications include barrel brewing system, product storage cold stabilization, room cooling for wineries, fermentation control cold chilling the juice, ice cream and yogurt process, chemical acid liquid cooling, cold storage of the final product for beverage and drinking.
Alternatively, you can use these glycol chillers for circulation between distillation tanks & stills heat removal for distilleries, control of fermentation temperatures, chilling after fermentation, storage cooling for Kombucha processing, etc.

Chapter 1: What is a glycol chiller?
Be quite different from the regular water chiller, Glycol chiller is a specially designed refrigeration system, and often involves the use of antifreeze for low-temperature cooling purpose.
For regular water chiller, we always use tap water or fresh water as the cooling medium. But for glycol chiller, we must go for glycol and water mixture due to the desired coolant temperature below Zero.
Glycol is a water-miscible coolant that is mostly used in heat transfer and cooling applications. Glycol can provide better heat transfer parameters than pure water, and can also be mixed with water to provide a variety of heat transfer characteristics.
Glycol as the chemical liquid comes in two ways: ethylene glycol and propylene glycol. Both materials are harmful to living things, But propylene glycol is most often used near food and ethylene glycol is most often used in industrial applications.
Pure water will freeze when the temperature comes into Zero, but glycol with water mixture will not have such frozen problem.
That’s why we call a water chiller is a glycol chiller when the temperature comes below Zero.
Chapter 2: How does a glycol chiller work?
To understand how does a glycol chiller work, we must first understand how a chiller works.
Glycol chiller, the same as a regular chiller is a refrigerator that includes a compressor, evaporator, condenser and a metering device.
An additional buffer tank is used with the chilling unit to provide additional system capacity to prevent excessive cycling, unexpected temperature fluctuations, and erratic system operation.
A chiller consists of two key parts:
One refrigeration unit which uses electrical energy to produce a cold fluid, and heat transfer coils which will move cold fluid from the refrigeration unit to the target area and hot fluid from the target area to the refrigeration unit.
Typically, the target area is the inside of a freezer or some other object that you want to cool. The refrigeration unit often consists of a compressor with some compressible heat transfer fluid such as freon.
From the above explanation, we can understand it is a chiller working principle.
Each chiller has an operating temperature range. This temperature range is determined by several variables, the most important of which are the boiling point and freezing point of the heat transfer fluid.
For regular chillers, the operating temperature should +5℃ and above. But for glycol chiller, the operating temperature always 0℃ even can lower to -35℃.
Glycol is prized as a heat transfer fluid because it can operate at a wide range of temperatures and can be mixed with water. The boiling and freezing points of glycol mixtures are a function of the relative amounts of glycol and water in the mixture.
The low freezing points of glycol and water mixtures make them ideal for cooling items below the freezing point of water.
Chapter 3: What is the glycol chiller used for?
Glycol chiller is a specific kind of refrigeration system, often used to cool a variety of liquids and other industrial or commercial applications.
By using a glycol chiller to lower the temperature of the product dramatically over a short period of time, depending on the production needs.
By using a glycol chiller can achieve the desired low temperature for your industrial or commercial usage.
Buying using a glycol chiller can provide a steady coolant for the special industrial application.
- Breweries. In breweries, the glycol chiller is used for cooling the wort,
for controlling the fermentation process and speed.
Glycol chiller can also for crash cooling vessels and prepackaging of hot food, finished product cold storageThe compressor is the core component of all water chillers, and also the power source of refrigerant compaction. Its effect is to convert the input electric energy into mechanical energy and to tighten the refrigerant.
- Wineries. Glycol chillers are widely used in the fermentation process, cold stabilization
can be also used for room cooling purpose
- Cider Mills. Fermentation control needs critical water temperature control. Glycol chiller can provide cold chilling the juice and
milk, also the cold storage of the final product.
- Distilleries. During the fermentation process, glycol chiller will provide a steady coolant for circulation between distillation
tanks stills for heat removal purpose.
5. Ice rink. Ice rink project needs glycol chiller to provide low temperature coolant which will make the water frozen into ice easily on the ice skating surface. Glycol chiller is the best choice of refrigeration system for cooling ice rink project.
6. Food industry. Glycol chiller can provide low-temperature coolant to guarantee the safety and consistent quality of frozen foods, food processing companies need a low-temperature cooling day in and day out.
7. Carbonated filling line
Glycol chiller can also be used for the carbonated drink or beverage filling line. For carbonated beverage process need glycol chiller providing a steady cooling source to maintain a certain temperature for the production process. So for all soft drinks, beers and carbonated drinks need some glycol chillers.
Chapter 4: How to size a glycol chiller for your business?
For the above information, we shall know the important role which glycol chiller plays not only in industrial but in commercial applications.
But how to size a correct glycol chiller for your business come into the point.
There are some useful tips for sizing your glycol chillers:
- Brewhouse Capacity, Provide total BBL (Barrel) size for the Brewhouse.
- Fermentation Tanks, Provide Quantity and BBL size for one or two different sizes of fermentation tanks.
- Brite Tanks, Provide Quantity and BBL size for one to three different sizes of Brite/Serving tanks.
- Wort Cooling, Do You Have A Cold Liquor Tank? Do You Have A Two-Stage Wort Cooler?
- Ice rink project, Provide the project square meters and layout drawing for reference.
If you have any other glycol chiller requirements, please send a chiller inquiry. You will receive an estimate of your brewery cooling load and a glycol chiller selection for your brewery.
Chapter 5: What temperature glycol should be?
It is important to use the correct ratio of glycol to water mixture, as not having enough glycol may damage the glycol chiller, while too much can make the solution less efficient.
But what’s the best ratio for glycol and water mixtures? We have rich experience in glycol ratio of glycol and water mixtures for glycol chiller cooling process:
16%glycol and 84%water when water temperature@0℃,
24%glycol and 76% water when water temperature@-5℃,
32%glycol and 68%water when water temperature@-10℃,
40%glycol and 60%water when water temperature@-15℃,
45%glycol and 55% water when water temperature@-20℃,
50%glycol and 50% water when water temperature@-25℃,
55%glycol and 45% water when water temperature@-30℃,
In summary, the lowest glycol chiller temperature you can achieve, the higher the ratio of glycol.
We can cite breweries typically using a 35% propylene glycol 65% water mixture, which can be measured using a glycol refractometer.
