What is Portable Glycol Chiller?
Portable Glycol Chiller is the refrigeration system that caters to the application according to your requirements.
The word ‘Portable’ in Portable Glycol Chiller indicates its flexible nature. Being flexible, it is also compact in design which makes it more land efficient.
It is mainly intended to provide cooling to the brewing industry and liquids such as alcohol and beverages. The cooling capacity starts from 1.5 tons and ends at 250 tons.
Various kinds of Glycols are used in Portable Glycol Chiller let’s take the example of propylene glycol. Propylene glycol is food-grade antifreeze and it has a low level of toxicity.
Antifreeze is always used when food needs cooling. During the production of food, the propylene glycol mixes with water and helps us in providing the required temperature for food preservation.
Propylene glycol is safer to use.
The other kind of glycol is ethylene glycol. It is moderately toxic and has a sweet taste. It is harmful if swallowed.
So, It is highly recommended not to use ethylene glycol in Portable Glycol Chiller. Because in case of pipe leakages the ethylene glycol will be mixed with food and drinks.
There is also automotive glycol avoid using these as they are not made up for industrial application. They may cause a fault in the compressor.
What are the Main Characteristics of Portable Glycol Chiller?
The Portable Glycol Chiller has certain features that help it in process of operation. Everyone seeks the good features in Portable Glycol Chiller.

Portable Glycol Chiller controls the temperature in four stages.
The temperature ranges from 0°C to -10°C, -10°C to -20°C and -35°C. The minimum temperature range starts from -5°C. But the temperature stability can be +/-2°C.
The Portable Glycol Chiller operates with high thermal conductivity and low viscosity at -°C temperature. Which results in increased heat transfer and less energy demand.
It protects application down to -50°C on any concentration and the lower concentration is needed to achieve the same freezing point in other alternatives.
It also has synergistic corrosion inhibitors in its pipelines and essential components to avoid corrosion.
A special material is used to prevent any leakages. Material like polyacrylate is employed on the surface coatings as adhesive.
Which are the Main Components of Portable Glycol Chiller?
The Portable Glycol Chiller is manufactured for Industrial applications especially. It has a few components that help it to operate smoothly.
It has the same components similar to its alternatives and other refrigeration systems.
The Portable Glycol Chiller is composed of an independent compressor, the thermal expansion valve, Control panel, power unit, condenser, and evaporator.
Compressor: The Portable Glycol Chiller is equipped with a quality compressor that guarantees energy efficiency, low noise, and long-lasting service time.
To ensure that the pressure inside the evaporator must be low and the refrigerant is also at low temperature, the compressor helps in pumping out the evaporated refrigerant.
It also compresses the low temperature and low-pressure gas into the high temperature and high-pressure refrigerant gas.
Condenser: The condenser in Portable Glycol Chiller is of two kinds.
- Air-cooled condenser
- Water-cooled condenser
The choice of condenser depends on your requirements and the load of the application. However, the refrigerant with high pressure and temperature is condensed into the liquid inside the condenser of the system.
The refrigerant located in the condenser releases the heat in the middle of either water or air with a lower temperature than it.
The temperature of water and air in the Portable Glycol Chiller must be lower than the refrigerant.
Thermal expansion valve: Thermal expansion valve has the most crucial role in Portable Glycol Chiller.
The Portable Glycol Chiller has a refrigerant that drops from the condensation pressure to the evaporation pressure so, the liquid from the condenser can easily be placed in any liquid receiver.
During this time, the refrigerant is in a state of normal temperature and high pressure. Then it passes through the expansion valve of the Portable Glycol Chiller to reduce the Boiling point.
The liquid travels to the evaporator to absorb heat and evaporate within a short time.
There are various kinds of expansion valves in Portable Glycol Chiller, which include thermal, pilot-operated thermal, electronic, and fixed orifice expansion valves.
Evaporator: The evaporator collects the heat that comes from the system. It is equipped with different types of evaporators.
- The first type is shell and tube evaporator.
- The 2nd type is the plate heat evaporator. (heat exchanger)
After passing from the expansion valve the liquid with low temperature and pressure journeys to the evaporator.
Once the heat is absorbed it heads up to the cooling towers or later returns to the compressor for cooling.
Control panel: It is an electronic device attached to the top side of the Portable Glycol Chiller that is used to control its whole process.
The Control panel is used by operators to set the configuration, program the system, and control the operation of the Portable Glycol Chiller.
Power unit: Power unit is the main supplier of electricity to your Portable Glycol Chiller.
The power unit is used to control the flow of electric current. It allows the minimum and maximum amount of electric current the Portable Glycol Chiller need.
Do Portable Glycol Chiller Saves Energy?
When it comes to chilling systems, every industrial application requires energy and a cost-efficient system.
The aim to choose such a Portable Glycol Chiller is to reduce the ultimate cost of production in a bid to maximize the profits.
There is a huge variation of price among the different sizes. Prices range starts from 500$ to 80,000$.
The Portable Glycol Chiller consumes very low power while operating.
There is no exact amount of energy consumed by Portable Glycol Chiller because it depends on certain factors that need to be analyzed.
Either your Portable Glycol Chiller is stored indoors or outdoor.
The energy consumption also depends on the power phase your system has and it may be a single or three-phase system.
There are two kinds of glycol as mentioned above. Using more ethylene glycol than necessary is more costly.
The ethylene glycol is concentrated and needs efficiency to circulate in the system. If you lower the usage of ethylene glycol from 40% to 20% the savings increase to 6%.
If we calculate 6% of savings for a 1000 tons size Portable Glycol Chiller at 0.45 KW/ ton
6% x 1000 tons x 0.45 KW/ton x (24x7x365 hours/years) x $0.08/KWh= $18,9000 per year.
This is the colossal amount that you can save.
Why Portable Glycol Chiller is Necessary for your Application?
Every industrial application needs a cooling system with maximum efficiency for uninterrupted production. The Portable Glycol Chiller is mostly used in extreme heat absorption.
The impure water creates the algae in pipelines which affects the production and efficiency of the application.
Portable Glycol Chiller is free from any water impurities. It is crystal clear and does not allow any impurities in the system.
- The pure water freezes at 0°C (32 F) and the ethylene glycol freezes at a temperature of -12.9°C (8.9F).
- The freezing points of Glycol and water are not linear. The 60% of ethylene glycol freezes at a temperature of -52.8C.
- The low freezing points make the Portable Glycol Chiller ideal for cooling items below the freezing point of water.
It is not necessary to cool the item below the freezing point, you can also use it for the normal process as well.
The Portable Glycol Chiller uses the mechanical refrigeration system to cool the recirculating fluid (Glycol) that supports the process of cooling the industrial application.
The evaporator of Portable Glycol Chiller comes with a brazed plate, which means its plates are stainless steel and prevent rust. The copper brazing material is used.
Ethylene glycol has low heat capacity than pure water. Each liter of ethylene glycol is easier to heat than the liter of pure water.
The temperature difference allows the glycol mixture to carry out the heat from Portable Glycol Chiller more quickly than pure water.
It is environmentally friendly. The emissions from the system do not affect ozone or cause global warming.
What are the Advantages of Portable Glycol Chiller for your Application?

What is the Difference Between Portable Glycol Chiller and Water Chiller?
The main difference between Portable Glycol Chiller and Water Chiller is the difference in the circulating fluid. The Portable Glycol Chiller uses ‘glycol’ as a circulating solution.
Whereas the Water Chiller uses the ‘water’ as a solution. Using water as Chiller fluid is economical and it can be sourced easily at low costs.
To achieve high cooling efficiency, it is necessary to use deionized and reverse osmosis water.
The Portable Glycol Chiller either uses ethylene glycol or propylene glycol as a circulating solution. Both solutions have the same capacities and physical properties.
Propylene glycol is safer to use than its alternatives.
The Water that is free from any impurity has a high freezing point. The freezing point is 32°F.
It is higher than Glycol which changes its solid-state at 8.9°F. The glycol has more refrigerant properties that are suitable for use in Portable Glycol Chiller.
Glycol also functions effectively even in low temperatures.
Mainly Portable Glycol Chiller is composed of a refrigeration component and tubing which contains the mixture of the glycol-water mixture as coolant.
The cool fluid from the refrigeration unit travels through pipes with the help of a thermal exchanger with a heating process.
After absorbing the heat, warmed fluid travels to refrigeration and is cooled, later sent back to the system for cooing.
How does a water Chiller work?
The water cooling system works by heat absorption and vapor compression. The basic component is Water Chiller is refrigeration that cools the fluid and pipes that circulate the fluid.
How do the Portable Glycol Chiller works?
Like every chilling system, Portable Glycol Chiller uses the essential component that helps it to run the application process smoothly.
The refrigeration and tubing contain a mixture of glycol and water. The glycol in a cool state travels to the storage unit.
The glycol will initially flow through the compressor unit which compresses the glycol and increase its pressure.
The compressor unit provides the force that helps the glycol fluid to circulate through the entire Portable Glycol Chiller. The fluid develops enough pressure to enter in next stage of the system.
The fluid then enters into the evaporator. The evaporator collects the heat from the entire system. The evaporator takes the help of fluid such as glycol which collects the heat from the application.
After absorbing the heat from the fluid, it will leave the fluid in a cool state and send it back to collect more heat.
The refrigerant is a very valuable part of the Portable Glycol Chiller. The refrigerant increases pressure and changes it into a gaseous state from the liquid state.
The gaseous state travels to the condenser unit.
At the condenser, the refrigerant will lose the whole heat that is collected from the evaporator. The condenser unit condenses the gaseous fluid by removing heat from it and reducing the volume.
The heat will be removed from the atmosphere with the help of cooling towers. This allows the condenser to move slowly from the condenser to the expansion valve.
In the expansion valve, the refrigerant will drop the high pressure and increase the volume of the refrigerant to a great extent.
This will help in creating the room for more heat from the refrigerant. Then the expansion valve allows refrigerant back to the system to start the process all again.
How to Select Suitable Portable Glycol Chiller for your Application?
The selection of a Portable Glycol Chiller depends on a load of your application process, footprints, and running time.
There are many Portable Glycol Chiller but vary in size and features. However, there are basic guidelines that must be followed to select the suitable Portable Glycol Chiller.
Always choose your Portable Glycol Chiller that uses ethylene. Because ethylene has lower cost and viscosity, also has better heat transfer properties.
However, the nature of ethylene is toxic and in case of spilling may result in damage. Always choose the stainless steel one or it should be coated with oil, grease, and protective film.
Determine the heat load of your application, this will help you to analyze the cooing capacity you need.
After the heat load, the next step is to select the type of coolant, target temperature, and flow rate process of application needs.
Your Portable Glycol Chiller must have the ‘Chiller performance curves’. Chiller performance curves help in limiting and exceeding the capacity of cooling.

The second step is to piping your connection. It is recommended to use a Y strainer, it resists any particle, shaving, and PVC glue from your mainline piping coming back to the system.
It needs to install the return line of the unit.
The third step is to verify power and reset breakers. It must be done by a certified electrician.
It is necessary to reset all breakers of the unit to make sure nothing was tripped during shipping.
It is important to leave power to Portable Glycol Chiller for at least four hours before firing up compressors. This allows the compressor to fire up any of the liquid refrigerant compressed inside.
Open the louvered access panel and fill the glycol inside the reservoir. After filling the glycol, the glycol will travel to the necessary components of the Portable Glycol Chiller.
The last step is to set the temperature protection. There is a free stat called S1 that’s low-temperature protection. If you want to prevent any freezing use S1.
It would automatically shut up if a high temperature is produced in the system. Press the set temperature button once and it will show you the temperature.
If you keep pressing up the arrow button it will increase the temperature and vice versa.
