What is a Low-Temperature Glycol Chiller?
A Low-Temperature Glycol Chiller is specially manufactured and designed for industrial processes.
You can identify by its name that it is used for low-temperature cooling requirements.
A Low-Temperature Glycol Chiller provides non-stop cooling. It can drop the temperature of the fluids to -40 degrees Fahrenheit.
A Low-Temperature Glycol Chiller uses a glycol mixture to meet the low-temperature requirements of your application.
It uses propylene glycol and ethylene glycol as a cooling medium in different industries.
Propylene glycol is mostly used in the food and beverage industries as it is harmless for human health.
A Low-Temperature Glycol Chiller dissipates the heat from the system into the air with the help of a condenser.
The complete guideline about working a Low-Temperature Glycol Chiller is described in the next sections.
A Low-Temperature Glycol Chiller uses glycol and water mixed in a specific ratio to fulfill the low-temperature requirements below the freezing point to cool down various applications.
It first cools the glycol mixture then circulates it through the pipes to cool down machinery and products etc.
What are the Working Principles of a Low-Temperature Glycol Chiller?
A Low-Temperature Glycol Chiller uses glycol as a coolant. Glycol is a thick translucent chemical compound.
Glycol is a very environment-friendly coolant as compared to other fluorinated gases. Other fluorinated gases can greatly affect the environment.
A Low-Temperature Glycol Chiller uses different processes and working principles to fulfill the requirements of large-scale industrial applications.
The refrigeration cycle for the Low-Temperature Glycol Chiller begins with low-pressure gas or liquid driven to the evaporator.
The evaporator boils the refrigerant by using heat obtains from the process water and glycol mixture.
It changes the state of a low-pressure liquid to a low-pressure gas.
This low-pressure gas then enters the condenser where ambient air dissipates heat from it.
When the heat is removed from high-pressure gas it becomes a high-pressure liquid then high-pressure liquid travels to the expansion valve.
The expansion valve also controls the amount of liquid refrigerant that enters the evaporator to restart the refrigeration cycle.
The condenser of a Low-Temperature Glycol Chiller can be of two types an air-cooled or water-cooled.
An air-cooled condenser of a Low-Temperature Glycol Chiller uses air to condense the high-temperature refrigerant gas into a liquid.
The air-cooled condenser can be placed in the open air for higher results.
On the other hand, a water-cooled condenser of Low-Temperature Glycol Chiller uses chilled water from a cooling tower for condensation of the refrigerant.
What are the Major Components of a Low-Temperature Glycol Chiller?
A Low-Temperature Glycol Chiller is specially designed for low-temperature requirements. The Major Components of this glycol refrigeration system are as follow;
A compressor is used to ensure the motion of the refrigerant throughout the process.

The condenser of a Low-Temperature Glycol Chiller is placed closer to the expansion valve and the compressor.
It is used to remove the heat from the refrigerant sent in an evaporator. There are two types of condensers. A water-cooled condenser and an air-cooled condenser.
- Expansion Valve
A Low-Temperature Glycol Chiller uses an expansion valve to expand the refrigerant and amplifies its volume during the process.
The evaporator is responsible to take heat from your application and send it to the refrigerant for the evaporation process.
The remaining water is cooled when the heat is extracted through the system.
- Power Unit
The power unit plays an important role in a Low-Temperature Glycol Chiller. It controls the flow of electricity by using power cables.
It may include a speed controller, starter, circuit breaker, etc.
- Control Unit

What are the Industrial Applications of a Low-Temperature Glycol Chiller?
A Low-Temperature Glycol Chiller is used to meet the low-temperature requirements of different industrial applications even below 0 degrees Celsius.
They are mostly used in the winery, breweries, and other food and beverage industries because of the glycol coolant.
The use of glycol helps the Low-Temperature Glycol Chiller to lower the temperature of the product efficiently.
Some of the industrial applications of a Low-Temperature Glycol Chiller are appended below.
- In the Breweries industries, the Low-Temperature Glycol Chiller is widely used to control the fermentation process and its speed.
- In crash cooling vessels and prepackaging, it is used as cooled storage.
- In the Wineries industry, it is used for stabilization of the cooling and fermentation process during the manufacturing and storing of wineries.

What should be the Ideal Temperature of a Low-Temperature Glycol Chiller for your Application?
The temperature adjustment of Low-Temperature Glycol Chiller is a very crucial factor. The temperature settings of this glycol chiller system are different for various industrial applications.
The extremely low temperature can slow down a Low-Temperature Glycol Chiller.
In the case of beer, it may freeze during the fermentation process. This happens if you have set the temperature very low.
To achieve colloidal stability the temperature of a beer should be 28 – 30 Â°F.
The ideal temperature according to your application is suggested by the engineers and tank manufacturers.
It will be better to ask it the engineers or manufacturers of your Low-Temperature Glycol Chiller.
What is the Difference between a Glycol and Antifreeze in a Low-Temperature Glycol Chiller?
Antifreeze and glycol in a Low-Temperature Glycol Chiller are not much different. They have the same functions. The glycol is basically of two types; ethylene glycol and propylene glycol.
The ethylene glycol is known as an anti-freezing agent in different chilling systems an odorless, colorless, viscous liquid.
It freezes at about -10 degrees Fahrenheit but a mixture of 40% water and 60% glycol can hold temperatures about -50 degrees Fahrenheit before freezing.
So glycols are used as a heat transfer medium for the proper flow of coolant throughout the process.
Antifreeze is a type of engine coolant. It is a cooler liquid mixed with water. It helps to regulate your engine when there is so cold outside.
What is the Method of Filling Glycol in a Low-Temperature Glycol Chiller?
It is necessary to fill glycol in a Low-Temperature Glycol Chiller at some time but mostly during installation, after a fluid leak, and after a flush.
There is a complete guide about how you can refill your Low-Temperature Glycol Chiller. First of all, you need to measure that how much glycol is in your system.
You can use a refractometer. Mix the right amount of water into glycol to ensure it is freeze-protected to the extent you require.
You have to mix the amount of glycol enough to protect your lowest temperatures in winters and refrigerant suction side.
You can fill it with only water at the start to clean out the piping, so will easily inspect it if there is any leakage or not.
Given steps should be considered when filling glycol in your Low-Temperature Glycol Chiller.
- Determine total system volume.
- Determine the concentration of glycol.
- Check the freezing point.
- Remove all air from your system.
Why is Glycol mixed with Water in a Low-Temperature Glycol Chiller?
The glycol is mixed with water in Low-Temperature Glycol Chiller to lower the freezing point of water during the process.
Pure ethylene glycol freezes at a low temperature of about -12 degrees Fahrenheit but when you will mix it with water. It begins to freeze at a lower temperature.
The water freezes below 0 degrees Celsius. The main purpose of adding glycol to water is to make it an anti-freezing agent.
This method was previously used in vehicles during extremely cold weather conditions.
In a Low-Temperature Glycol Chiller, the glycol increases the heat capacity of the water. The proper amount of water and glycol is important for efficient operation.
The manufacturer of your low-temperature system can suggest you better in this regard.
You can also test for anti-freeze in water with a very easy and quick method. Drop your sample to the fill line then break the three ampules in sequence.
Wait for about 30 seconds for its color to form, if you see a dark blue color in the pouch there is ethylene glycol is present.
