Glycol Chiller: Your Premier Choice
Of Glycol Cooling Chillers

A glycol chiller is also named low-temperature chiller, implying that the chilled water temperature is minus 0 degrees centigrade to -35 degrees centigrade.

TopChiller is a leading glycol chiller manufacturer and supplier, our glycol chillers including air cooled glycol chiller and water-cooled glycol chiller.

A glycol chiller is actually a refrigeration system using to cool a bath or tub of an antifreeze called “propylene glycol”, or just “glycol” for short.

This cooled liquid is pumped through a looped circuit of tubing connected to the input and output sections of the glycol chiller. This is the main cooling line of a glycol chiller.

Glycol chillers manufactured by TopChiller are some kinds of popular industrial chillers for special industrial applications.

What is the glycol chiller working principle?

Now let me cite the glycol chiller for beer as an example, please refer below information:

Propylene glycol is combined with water to create a chilled mixture that’s pumped from the glycol power pack through the cooling lines that run parallel to your beer lines.

Both distinct lines are kept cold by the internal moisture barrier in the trunk line and foil wrap around each glycol line.

Some people will always ask why glycol is used in your glycol chiller?

The use of an industrial inhibited glycol and water mixture is recommended in most water chiller systems.

Ethylene and Propylene are the two standard types of inhibited glycols commonly used. As we all know if the water temperature goes down to 0℃, the water will be frozen to be ice.

So the main job of glycol is to prevent freezing of the process fluid and ensure consistent flow at the operating temperature.

A glycol chiller is a special refrigeration system, mostly used to cool a variety of liquids including alcohol, chemical liquid, and other beverages.

Using a glycol chiller allows producers to lower the temperature of the product dramatically within a limited time, depending on the production requirements.

For glycol chillers, Propylene glycol and water mixture play an important role in the application of a glycol chiller, more so the working principle.

For chilling in brewing, glycol chiller plays an important part in the refrigeration.

For brewing industries, There are some processes where decreasing or maintaining temperature is mostly important – like crash cooling beer after fermentation, keeping a steady temperature during fermentation (which generates heat), or cooling the wort after an initial boiling process.

TopChiller offers a variety of glycol chillers from cooling capacity 5Ton to 180Ton and glycol temperature at -5℃ to -35℃.

These full-range glycol chiller models are most suitable for certain critical industrial applications including cooling and dispensing beer, water, chemical liquid and other beverages where there is limited refrigeration.

TopChiller glycol chillers can be added to an existing remote glycol system for additional cooling capacity.

There are 4 stages of glycol chiller temperature controlling range, 0℃ to -10℃, -10℃ to-20℃ and -20℃ to -30℃. If you have special requirements, we can make -35℃ glycol chiller. But remember that the temperature stability is +/-2℃.

Glycol Chiller: The Complete Buying Guide from TopChiller

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.

Glycol chiller is a water-cooling device that provides a cooling device with constant temperature, constant current and constant pressure.

Glycol chiller is to inject a certain amount of water into the internal water tank of the machine.

The passing refrigeration system cools the water, and then the circulating water pump inside the machine injects the cold frozen water into the equipment to be cooled.

The heat inside the equipment is taken away, and the high-temperature hot water has again flowed into the water tank for cooling.

For regular water chiller, we always use tap water or freshwater 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 is the chemical liquid that 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 a 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 works, 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 glycol chiller consists of two key parts:

One glycol chiller 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.

Let’s explain what’s the working principle of a glycol chiller in details:

Glycol chiller, as the name suggests, is the chiller with ethylene glycol as the coolant for the chiller.
The structure of the glycol chiller consists of a compressor, an evaporator, a condenser, a throttling element, and an electric control system.

In order to ensure the stable operation of the glycol chiller, we recommend preventing the explosion. Measures to buy explosion-proof chillers as much as possible.

In order to ensure that the pressure inside the evaporator is sufficiently low, it is ensured that the refrigerant is pumped away by the evaporated refrigerant at such a low temperature, and the low temperature and low pressure are compressed into a high temperature and high-pressure refrigerant gas.

The high temperature and high-pressure refrigerant of the condenser are condensed into a liquid in the condenser. The refrigerant in the condenser releases heat between the air or water lower than its temperature.

Of course, the temperature of the air or water must be higher than that in the chiller. The temperature of the refrigerant should be low, otherwise, the refrigerant would not be able to exotherm.

How to throttle + after the throttle, the refrigerant of the chiller drops from the condensing pressure to the evaporation pressure, so the liquid from the condenser can be placed in the liquid reservoir.

At this time, the refrigerant is at normal temperature and high pressure. The state, after the expansion valve, lowers the boiling point and enters the evaporator liquid to absorb heat and evaporate.

The low-temperature and low-pressure refrigerant liquid exchanges with the evaporator after passing through the restrictor, and becomes saturated or superheated steam upon absorption of heat, thereby facilitating the compressor.

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 glycol chiller working principle.

Each glycol 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.

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 comes to the point.

There are some useful tips for sizing your glycol chillers:

  1. Brewhouse Capacity, Provide total BBL (Barrel) size for the Brewhouse.
  2. Fermentation Tanks, Provide Quantity and BBL size for one or two different sizes of fermentation tanks.
  3. Brite Tanks, Provide Quantity and BBL size for one to three different sizes of Brite/Serving tanks.

Hazard analysis of overheating of glycol chiller

When using a glycol chiller, be sure to pay attention to the problem of overheating, because once it is overheated, it will adversely affect the working efficiency of the glycol chiller, which is not conducive to the production of the enterprise.

Therefore, the enterprise should have a deep understanding of the second hazard caused by the overheating of the glycol chiller.

  • Once the ethylene glycol chiller is overheated, it will have a great impact on the operation stability of the refrigeration equipment. Once the temperature and environmental heat increase, many cold sources will be wasted.                                                                                             Under the premise of continuous loss of cold sources, the ability of glycol chillers to reduce ambient temperature is severely limited.                                                                                                If there is a seriously high-temperature problem, the efficiency of the glycol chiller is low, which seriously affects the efficient production of the enterprise.
  • When using a glycol chiller, it is necessary to recognize the danger of overheating to the operation, because if the temperature of the working environment is high, causing a lot of heat to be processed in a timely and effective manner will inevitably affect the safe operation of the glycol chiller.                                                                                                                                   Once the running time is longer, the harm is greater. Therefore, the company needs to correctly understand the impact of a good environment on the glycol chiller.
  • Once overheated, it will affect the shortened life of the glycol chiller, which will increase the cost of the equipment used by the enterprise and affect the stable development of the enterprise.                                                                                                                                                   In order to keep the operation of the glycol chiller safe and stable, it is necessary to provide a safe and comfortable working environment for the glycol chiller. Avoid problems such as high temperatures and other factors that affect the safety of the equipment. Reduce the troubles of various types of faults for glycol chillers.

How to maintain the cooling performance of your glycol chiller?

The glycol chiller mainly supplies cooling water to the heating part of the product to cool down and achieves the purpose of refrigeration.

Glycol chiller is a refrigeration device used in the electronics, chemical, and plastic industries. How to maintain a better cooling effect of the glycol chiller? What about the operation of the refrigeration system?

  1. Regularly check the core of the glycol chiller – compressor
    In the operation of the glycol chiller, the compressor is the core of its operation. Its performance factor can affect the stability of the use of the glycol chiller. If the compressor fails, the cost is relatively high.
  2. Affect the use of glycol chillers. Once the compressor is damaged seriously, it will also clean the abnormalities of other accessories. Therefore, the regular inspection of the glycol chiller compressor is good.
  3. Regularly clean the condenser and evaporator of the glycol chiller
    In the glycol chiller, the condenser and evaporator are the second-largest components. Cleaning is more important. It is recommended to clean it once every six months.
  4. The glycol chiller uses ethylene glycol to water as circulating water for refrigeration. The substance or precipitated impurities scale affects the heat transfer effect. Excessive fouling of the evaporator of the glycol chiller condenser also reduces the flow cross-section of the cooling water, reduces the amount of water, and increases the condensing pressure.
  5. Therefore, it is recommended to wash at least once a year to remove scale from the pipe. It is recommended to perform water treatment on the water.
  6. Regularly check the safety valve of the glycol chiller
    When using a glycol chiller, the user needs to understand that the condenser and the pressure vessel belong to the pressure vessel. The safety valve should be installed on the high-pressure end of the glycol chiller, ie, the condenser body, once the glycol chiller unit is in the non- In normal working conditions, the safety valve can automatically relieve pressure to prevent high-pressure damage to the human body.
  7. Regular replacement of glycol chiller lubricants
    After the long-term operation, your glycol chiller will cause the oil quality of the lubricating oil to deteriorate, and the impurities and moisture inside the lubricating oil will also increase.
  8. Therefore, it is necessary to set a time to regularly check the lubricating oil quality of the glycol chiller and find problems. Replace it in time.
