Glycol Chiller: The Complete Buying Guide from TopChiller

Chapter 1: What is a glycol chiller?

Being 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 purposes.

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

Glycol chiller is to injects 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 a regular water chiller, we always use tap water or freshwater as the cooling medium.

But for the 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 a 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 to 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 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 detail:

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.

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

Compressor
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.

Evaporator
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 be +5℃ and above. But for glycol chiller, the operating temperature is 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, depending on the production needs.

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.                                                                                                                                                   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 achieve 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.

Glycol Chiller is one of the most advanced technologies of refrigeration systems.

It helps not only to maintain accurate temperature control but it is an environment-friendly alternative for chillers that use toxic chemicals for their applications.

Glycol Chiller helps cool a variety of liquids. It comes in a variety of sizes and temperature ranges depending upon your applications.

In this guide, you will have all the necessary information about Glycol Chiller.

You will come to know about:

1. What is a Glycol Chiller?

Glycol Chiller is one of the most popular refrigeration system technologies. As the name indicates, it uses Glycol as a coolant.

Most industrial chillers use water as a coolant, but Glycol Chiller uses a Mixture of Glycol and Water as a coolant.

Glycol is alcohol. It has two hydroxyl groups attached to the carbon atoms.

Glycol is a water-soluble chemical compound mixed with water to provide a wide range of better heat transfer parameters

It is commonly known for its applications in the online industry.

There are two types of glycol. Ethylene glycol and propylene glycol.

Glycol Chiller uses Ethylene glycol commonly known as Ethylene Glycol Antifreeze as well as Ethane-1, 2-diol, and Industrial Glycol as a heat transfer fluid.

Glycol Chiller uses Ethylene Glycol, a very good coolant, but its cooling properties are increased to the maximum level when mixed with water.

Glycol Chiller Manufactured by TopChiller

2. How does a Glycol Chiller Works or Operates?

Glycol Chiller works in a cyclic process.  It uses Glycol-water as a refrigerant.

Glycol-water mixture absorbs heat energy from a source and converts it into a gaseous phase.

The gaseous refrigerant is then distributed to a condenser, which expels the heat through evaporation and condensation to a cooling tower.

This heat exchange condenses the cooling medium back into a cooler liquid sent back to the process heating source to begin the cycle again.

Glycol Chiller has a pumping system, which circulates the normal temperature glycol-water mixture from the Glycol Chiller to the process.

Glycol-water mixture absorbs heat from the environment or process and increases the temperature of the coolant.

Then, it returns a glycol-water mixture to the Glycol Chiller.

Glycol Chiller work on the principle of phase-change of its refrigerant from a liquid state to a gaseous state. It also involves compression.

First of all, the low pressure and normal temperature glycol-water mixture enter the evaporator. The heat from the environment boils the refrigerant.

The evaporator converts the low-pressure glycol-water mixture into a low-pressure gas. Then compressors compress low-pressure gas into a high-pressure gas.

The high-pressure gas is then transferred to the valve which controls the number of liquid refrigerants. This cycle repeats itself and Glycol Chiller starts chilling.

Glycol Chiller has two different types of condensers and air-cooled condensers and a water-cooled condenser.

An air-cooled condenser uses air from the surroundings to convert hot refrigerants into a liquid state.

It uses air to lower the temperature of the coolant.

It is placed either inside or outside the Glycol Chiller. It rejects the heat from the process to the air in the environment or surroundings.

A water-cooled condenser uses water in a cooling tower to change the phase of refrigerants.

3. Why do we use a Mixture of Water and Glycol in a Glycol Chiller?

There is a big difference between using proper coolant like glycol-water mixture and water for a Glycol Chiller.

Water will help you to help to keep the internal system of your Glycol Chiller cool but, it does not work the way glycol does.

Water boils faster and at a lower temperature than a coolant like glycol. In winters you may have to risk your chiller to block or crack if you run you with only plain water.

The coolant for the Glycol Chiller has also been formulated to keep the parts in your Glycol Chiller from becoming corroded.

Water does not possess this property. Instead, it promotes corrosion.

Using a glycol-water mixture reduces the risk of corrosion.

Instead of pure glycol, Glycol Chiller uses a mixture of water and glycol for its working.

Glycol has good Antifreeze properties.

Pure or distilled water freezes at 32 degrees Fahrenheit or zero degrees Celsius were as pure ethylene glycol changes to its solid-state at 8.9 degrees Fahrenheit.

When a glycol-water mixture is used, the freezing point of the coolant also changes.

For example, 10 percent ethylene glycol will freeze at 25.9 degrees Fahrenheit, while a 60 percent glycol solution will freeze at -63 degrees Fahrenheit.

Water can transfer heat more heat than glycol but it is not suitable for low-temperature environments.

It is one of the best heat exchangers but it can’t beat glycol as a coolant. Glycol has more benefits as a coolant in a chiller.

It shows that using a mixture of glycol and water has more advantages. It enhances the freezing properties.

It enables us to keep the coolant in a desirable fluid state. This shows that the glycol-water mixture is the best coolant for a chiller.

It resists corrosion; hence widely preferred in industrial and commercial processes as well as cooling applications.

4. What are the Main Components of a Glycol Chiller?

A Glycol Chiller plant consists of a water system, refrigeration system, and control system.

The refrigeration system consists of a compressor, thermal expansion valve, condenser, a tube or plate heat exchanger, and refrigerant pipelines.

• Compressor

It compresses the refrigerant to high pressure and sends it out to the condenser to be cooled.

• Condenser

It is one of the refrigeration unit’s essential parts.  It condenses the refrigerant back into a liquid form.

They are available in both air-cooled types and water-cooled types in the market.

• Thermal Expansion Valve

It plays a crucial role in Glycol Chiller. The condensation pressure of the refrigerant drops to the evaporation pressure crucial in the liquid receiver. It precisely monitors the flow of refrigerant entering the evaporator.

• Tube or Plate

It is a heat exchanger. It is the place where refrigerant and glycol of you and most of the crucial glycol for its working.

Glycol has good Antifreeze properties.

Pure or distilled water freezes at 32 degrees Fahrenheit or zero degrees Celsius were as pure ethylene glycol changes to its solid-state at 8.9 degrees Fahrenheit.

When a glycol-water mixture is used, the freezing point of the coolant also changes.

For example, 10 percent ethylene glycol will freeze at 25.9 degrees Fahrenheit, while a 60 percent glycol solution will freeze at -63 degrees Fahrenheit.

Water can transfer heat more heat than glycol but it is not suitable for low-temperature environments.

It is one of the best heat exchangers but it can’t beat glycol as a coolant. Glycol has more benefits as a coolant in a chiller.

It shows that using a mixture of glycol and water has more advantages. It enhances the freezing properties.

It enables us to keep the coolant in a desirable fluid state. This shows that the glycol-water mixture is the best coolant for a chiller.

It resists corrosion; hence widely preferred in industrial and commercial processes as well as cooling applications.

Glycol Chiller Heavy Duty Compressors

5. How to Choose the Right Proportion of Water for your Glycol Chiller?

Glycol Chiller uses a 60 by 40 proportion of glycol in the glycol-water mixture.

This percentage of glycol makes it useful for rapid temperature control. It enhances the Antifreeze properties of the Glycol Chiller.

It causes a rapid decrease in temperature without freezing the coolant in the refrigeration unit. Glycol Chiller uses a high concentration of glycol water coolant.

Glycol at concentrations of one to two percent is toxic to bacteria and algae.

The concentration of one percent of glycol is a nutrient for bacteria and algae.

Hence, the concentration above one percent discourages the growth of algae and bacteria in pipelines and refrigeration units. These properties of glycol-water mixture make it desirable for chillers.

6. What are the Advantages of a Glycol Chiller for your Application?

Glycol Chiller has many advantages over the conventional water chiller. It is more reliable.

Water Chillers use pure water as a coolant. It should be free from impurities.

There is usually a high cost to buy water quality management equipment to purify water.

Whereas Glycol Chiller uses a mixture of Glycol and Water; It does not cost that much.

• Food and Beverages:

Glycol Chiller is eco-friendly. Manufacturers globally use it to lower the product’s temperature to the desired level in a short period.

It is widely used for cooling fermentation tanks, Brite tanks, and Wort coolers in the brewing industry.

Beer lovers expect the same taste they love. To maintain the quality of the beer, Beer producers require a good chiller for accurate temperature control.

Glycol Chiller does this job efficiently and effectively. It is best to monitor and control temperatures.

The fermentation process releases heat into the environment. It transfers some of the heat to the fermenter.

The heat release in this process can cause an increase in the average temperature of the beer.

The performance of yeast is greatly affected by the temperature of the fermentation. It is not enough to control the average temperature of the brew.

The temperature must be controlled at all times to avoid producing fermentation by-products that are difficult to remove later. Glycol Chiller help to maintain that desired temperature.

Without a Glycol Chiller, your beer temperature can vary by as much as 10 degrees Celsius during the fermentation process.

This produces unpredictable and undesirable effects on the yeast and a combination of flavors that cannot be reproduced from one batch to the next.

Yeast pitched at a higher temperature produces high levels of diacetyl.

Diacetyl has a buttery flavor in the beer.

A small amount of this flavor may be enjoyable, but the diacetyl flavor is rarely acceptable in masses.

High temperatures at the beginning of the fermentation process can cause the yeast to undergo a flurry of early reproduction.

This can have many effects on your beer during the later stages of fermentation.

A Glycol Chiller can bring your Wort to the accurate temperature for yeast pitching and maintain it there throughout the fermentation process.

Glycol Chiller is a profitable and effective way of cooling liquids such as a brewer’s Wort.

• Power Generation:

Today’s railway industry uses the most influential electric motors that are operated energy-efficiently by using control systems.

They have inverters that are powered by motors that produce a considerable amount of heat.

To run the engine smoothly, this needs to be removed from the engine.

Glycol Chiller, Water-glycol mixtures are used for applications with high power consumption and in confined spaces.

As the trend is towards high-performance motors in high-speed trains and underground trains and trams, it demands efficient cooling systems. Glycol Chiller is the best solution for all.

The conversion of a single-phase alternating current supply to a three-phase alternating current supply causes many heat losses.

It is necessary to remove this enormous amount of heat for the proper functioning of the system.

Modern technologies use Glycol Chiller to remove this huge amount of heat and maintain the temperature.

• Manufacturing:

The manufacturing industry uses Glycol Chillers to remove heat from their processed products, like the plastic industry.

Pharmaceutical companies and the medical industry use Glycol Chillers to maintain the temperature.

Glycol Chiller plays a vital role in maintaining the sustainability of the products.

11.       How to Troubleshoot your Glycol Chiller Problems?

In this section, you will come to know about troubleshooting problems that you can face while operating your Glycol Chiller.

• Your Glycol Chiller may not Power Up :

Sometimes your Glycol Chiller does not power up due to losing connections, improper line voltage, and fuse.

Your breaker may fuse due to high voltage; make sure it is properly working.

• Insufficient Fluid Flow

Always make sure that your cover or close the tank of your Glycol Chiller.

If it is not closed, then it will be exposed to air.

Air has water vapor in it. It will enter the bath and decrease the glycol level in your Glycol Chiller. This will result in an insufficient flow of fluid.

• Why should you always keep the Valve Closed?

It would be best if you always kept your pump wholly closed. A partially closed pump will decrease the volume of coolant that is a glycol-water mixture.

It will cause an insufficient flow of liquid, which ultimately results in inadequate cooling.

• Keep an Eye on the Temperature of your Glycol Chiller bath:

Check the temperature of the bath of your Glycol Chiller almost daily. It should be in the range recommended by the manufacturer of your Glycol Chiller.

If its temperature is higher or lower than this range, it will affect your application badly.

• Is your Glycol Chiller Operating Smoothly?

It is effortless to determine that whether your Glycol Chiller is operating smoothly or not.

You can examine it by yourself. Just listen to the noise produced by the motor. If you find something unusual then, repair it.

If you find this task more technical, then call a professional technician to repair it for you.

• Why your Glycol Chiller makes a Beeping Noise?

Your Glycol Chiller sometimes makes a beeping noise.

It is built in the operation of a Glycol Chiller to prevent damage to its internal components. It is a low glycol warning signal.

Your Glycol Chiller produces this sound when the level of glycol is low. When it happens, you should fill the glycol tank.

Then it will stop making that noise. And it will restart its pump.

• How to Change the Temperature Scale?

Suppose you want to change the temperature scale of your Glycol Chiller between degrees Celsius and Fahrenheit. Press and hold the SET button for 6 seconds.
