Your Premier Glycol Chiller Manufacturer and Supplier in China
Glycol chiller is one kind of low-temperature chiller using glycol water as the circulating coolant to achieve minus temperature for industrial and process applications.
TopChiller is a professional glycol chiller manufacturer and supplier since the year of 1999.
As the leading glycol chiller company, TopChiller provides various of glycol chillers from 1.5ton to 120ton refrigeration capacity, and air-cooled glycol chiller and water-cooled glycol chiller based on your specific requirements.
Why do we need to add glycol into the chiller?
As we know, water will be iced once the temperature getting 0℃ or even below, glycol is helping water anti-freezing into iced, that’s why we call it is glycol chiller.
Generally, a glycol water chiller consists of a refrigeration system, water system, and control system.
The refrigeration system is composed of an independent compressor refrigeration system, including compressor, condenser, thermal expansion valve, a plate heat exchanger(shell and tube heat exchanger), and refrigerant pipeline.
Let’s have a look at the working diagram of glycol chiller:
1. The compressor of glycol chiller
TopChiller glycol chiller uses top brand scroll and screw-type compressor features energy efficiency, low noise, and long service time.
In order to ensure that the pressure inside the evaporator is low enough and that the refrigerant is at such a low temperature, the compressor is used to pump out the evaporated refrigerant and compress the low temperature and pressure into the high temperature and pressure refrigerant gas.
2. Condenser for a glycol chiller
Glycol chiller designed by TopChiller using air-cooled type or water-cooled type condenser for your choice.
The refrigerant with high temperature and pressure is condensed into liquid in the condenser. The refrigerant in the condenser releases heat in the middle of air or water with a lower temperature than it.
Of course, the temperature of air or water in the chiller must be lower than that of the refrigerant.
3. Thermal expansion valve in a glycol chiller
The thermal expansion valve plays an important role in a glycol chiller. The refrigerant of glycol chiller drops from the condensation pressure to the evaporation pressure, so the liquid from the condenser can be placed in the liquid receiver.
At this time, the refrigerant is in the state of normal temperature and high pressure, and then passes through the expansion valve to reduce the boiling point, and the liquid enters the evaporator to absorb heat and evaporate.
4. The evaporator in a glycol chiller
There is two type of evaporator in glycol chiller- shell&tube type and plate heat exchanger.
After passing through the thermal expansion valve, the low-temperature and low-pressure refrigerant liquid exchanges with the evaporator.
Once the heat is absorbed, it becomes saturated or overheated steam, which can be returned to the compressor for refrigeration.
With 20 years of design and make glycol chillers, TopChiller is willing to provide all types of high-quality glycol chillers for our valued customers.
Glycol chillers are widely used in modern industries, some typical applications of glycol chillers include cooling for breweries, wineries, cider mills, spirits, and some other critical industrial and commercial applications

What is a Glycol Chiller?
Glycol chillers are special refrigeration systems that use glycol as the main refrigerant for maintaining cool temperatures in different applications.
What are the Applications of Glycol Chillers?
You will use the glycol chillers in a number of industrial applications to cool off different equipment.
It will help in lowering the overall temperatures of different products within a very short period.
Here are some of the applications where glycol chillers come in handy.
· Brewing Industry
You will use the glycol chillers in the brewing industry to cool off different types of equipment.
Apart from that, you will use it to cook different types of liquids such as beverages and alcohol in the breweries.
You can use in applications such as crash cooling of beer during and after the fermentation process.
What are the Main Parts of the Glycol Chillers?
Glycol chillers are basically special types of refrigeration systems with special components such as evaporators, condensers, metering devices and compressors.
Here is a brief description about the main components of the glycol chillers.
You will depend on the glycol chillers to help in the elimination of heat from the glycol refrigerant.
It is available in different sizes and quality specification depending on your personal or custom requirements.
· Expansion Valve
The expansion valve will come in handy when you will need to increase the volume and reduce the pressure of the refrigerant.
You can choose among the different types of expansion valves including thermal, electronic, pilot operated thermal and fixed orifice expansion valves.
· Water Boxes
You will find the water box in a water-cooled glycol chiller which helps in controlling the flow of water within the chillers.
It will help in the segregation and straight flow of water within the entire glycol chiller system.
You will depend on the compressor to create enough pressure that will move the refrigerant through different points.
Here, you will choose between the four main compressors including scroll, screw, reciprocating, and centrifugal compressors.
The evaporator will help in the collection of the heat that comes from the system.
It goes ahead and fills up the unwanted heat into the glycol refrigerant to take it to the cooling towers.
· Power Unit
The power unit acts as the main electric power supplier to the glycol chiller systems.
You can control the flow of electric current through the power unit of the glycol chillers.
· Control Panel
You will use the control panel to configure, program and monitor all the operations of the glycol chillers.

How Do the Glycol Chillers Work?
Glycol chillers have refrigeration components and tubings that contain mixtures of glycol and water.
In its cool or chilled state, the glycol water fluid or refrigerant will move from the main storage unit.
Here are the main steps where the glycol-water mixture or fluid will pass through.
· Compressor Unit
It will flow through the compressor unit which will compress the water-glycol fluid and increase the pressure.
It will provide it with the right force that it needs to flow through the entire glycol chiller system.
Depending on the type of compressors, the fluid will develop enough pressure and flow to the next stage.
· Evaporator Unit
Here, the fluid will move to collect the heat that the evaporator collects from the system.
The evaporator uses the help of an ever-flowing fluid such as water which collects the heat from the system application.
As soon as the glycol water fluid mixture reaches the evaporator, it will collect the heat from the flowing water.
After collecting the heat, it will leave the water in a cool state, then allow it to flow back to collect more heat.
The refrigerant will increase in pressure and heat and then change from a liquid state to a gaseous state.
It will then flow straight to the condenser which is the next step in the whole process.
· Condenser Unit
This is the point where the refrigerant will lose the heat that it collected from the evaporator.
The condenser will condense the gaseous fluid by eliminating the heat and reducing the volume.
It will get rid of the heat through the air blowing in the atmosphere of take the heat to the water cooling towers.
This will allow the refrigerant to move slowly from the condenser and to the expansion valve.
· Expansion Valve
Here, the refrigerant will drop the high pressure and then increase the volume of the refrigerant significantly.
This will create enough room for the collection of enough heat from the refrigerant.
It will then allow the refrigerant to flow back to the compressor to start the process all over again.
