Product Description

Industrial Glycol Chiller For Cooling Fermentation

The industrial glycol chiller is a low-temperature chiller for industry and process applications that uses ethylene glycol water as a circulating coolant to achieve low temperatures.A chiller is a refrigeration system used to cool a barrel of ethylene glycol to lower its temperature. The glycol is then passed through a closed loop of one or more pipes connected to the glycol chiller. This circulates the cooled glycol and helps lower the temperature of anything attached to the system.

Industrial glycol chiller for fermentation is also called fermentation chiller,is a refrigeration device that used to cool the fermentation chamber by releasing heat from the chamber through glycol solution towards water.Because yeast generates heat as it ferments, regulating the temperature of the fermentation chamber can be a challenge. Breweries, wineries and breweries all require temperature control solutions during fermentation and storage. Maintains ideal fermentation temperatures to control fruity esters and prevent harsh solvent-flavored fusel alcohols. For high-quality beverages, stable and efficient cooling solutions are a must. There are many different methods of fermentation cooling. Using a portable fermentation chiller is the most effective way to keep your yeast strain within

Industrial glycol chillers are with specific components like the Panasonic/Danfoss compressor, air-cooled or water-cooled condenser, refrigerant water tank, glycol pump, stainless steel plate or shell and tube heat exchanger, control panel, expansion valves, and protecting devices, etc. For such low temperature glycol chiller ,it uses R404a refrigerant.

6.What is the Difference Between Glycol Scroll Fermentation Chiller and Glycol Screw Fermentation Chiller?

There are two types of glycol fermentation chiller: one is air-cooled glycol fermentation chiller ,the other is water-cooled glycol fermentation chiller ;

Air-cooled glycol fermentation chillers use ambient air to dissipate heat from the fermentation processes. They are energy-efficient, space-saving, and less maintenance that helps save money.

Water-cooled glycol fermentation chillers use water from an external water cooling tower to dissipate heat from the fermentayion processes. These systems are longer lifespan, Relatively quiet, and more consistent cooling performance than the air-cooled fermentation chiller.

Why Glycol Is Used for Cooling?

The most commonly used coolant in a chiller is water or a mixture of water-glycol. Glycol-based coolants consist of either ethylene glycol or propylene glycol. The main advantage of glycol coolants is their anti-freeze properties. Pure water freezes at 0 degrees C, while 30% ethylene glycol freezes at -14 degrees C. The low freezing point of glycol mixtures makes them ideal for cooling items that are below the freezing point of water. Although glycol has a lower heat capacity than water (each kilogram of glycol is easier to heat than one kilogram of water), the high temperature difference allows the glycol mixture to dissipate heat more quickly than pure water. The glycol mixtures are more suitable for applications where the chiller must quickly dissipate a large number of heat. In addition to providing excellent heat transfer parameters, glycol tends to discourage algae growth in heat transfer equipment.

How Does An Industrial Glycol Chiller Work?

A glycol chiller is composed of a refrigeration component and tubing containing a water-glycol mixture as coolant. Chilled fluid from the refrigeration unit is channeled through the piping associated with a thermal exchanger surrounding a heated process. After absorbing heat from the associated process, the hot coolant is returned to the refrigeration unit for cooling after which the process is repeated.

A glycol chiller consists of a compressor, an evaporator, a condenser, a throttling element, and an electric control system. Let’s see what’s the working principle of a glycol chiller:

 Glycol Chiller Working Principle

The Ratio of Water to Glycol to Use

It is important to use the proper ratio of glycol to water mixture in the cooling system depends on the coldest temperature you need during operation, as insufficient glycol can cause the system to freeze, possibly bursting pipes and even destroying the chiller evaporator even may damage the glycol chiller, while too much glycol to a chiller system will result in an inefficient system.

But what’s the best ratio for glycol and water mixtures? Please see below glycol ratio of glycol and water mixtures for the glycol chiller in your cooling process:



Water Temperature






















How I Can Choose The Right Industrial Glycol Chiller For Your Application?

There are four important chiller specifications you need consider when you choose a chiller for your application :the cooling capacity for chiller ,the voltage required for operation, the associated pump horsepower and flow rate (contact us for custom selection), refrigerant, and the evaporator type.

9.1 Air-Cooled Glycol Chiller or Water-Cooled Glycol Chiller

There are two types of glycol chiller: one is air-cooled type, the other one is water-cooled type.

Air Cooled glycol scroll chillers use aluminum fin+fan as condensers that is similar to the “radiators” in a car.They use a fan to force air through the refrigerant coil. Unless they are specifically designed for high ambient conditions, air-cooled condensers need to operate effectively at an ambient temperature of 45℃ or less.

Water Cooled glycol scroll chiller use shell and tube as condensers.The heat enters the condenser water from the refrigerant vapor. The warm condenser water is then pumped to the water cooling tower, where the heat from the process is eventually vented to the atmosphere.

9.2 Calculate Right Cooling Capacity For Chiller

One of the most frequently ask about how we can know the cooling capacity for chillers.  We use KW ,Ton, But/h,Kcal/h to choose chiller cooling capacity :1 KW=860 kcal/h ;  1 TON=3.517 KW;1 KW=3412 Btu/h;

There is also a formula to calculate the cooling capacity for chiller:.

Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-T2)/0.86

Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)

Oversize the chiller by 20% Ideal Size in KW = KW x 1.2

Noted : T1:Incoming Water Temperature (℃)      T2:Required Chilled Water Temperature(℃)    


For example, what size of chiller is required to cool 10m³ water from 35°c to 15 °c in 1 hour?

Temperature Differential = 35℃-15℃=20℃

Water Flow Rate = 10 m³/hour

Cooling Capacity in KW = 10 x 20 ÷ 0.86 = 232 KW

Oversize the chiller = 232 x 1.2 = 278.4KW

278.4 kw cooling capacity for chiller is required.

9.3 Power

Different countries and regions have different standards for industrial electricity, the common power supplies are 208-230V, 380-420V,440-480V,50Hz or 60Hz, 3phase.

Such in Philippines ,the power supply is 220V 60HZ 3PH , 380V 60HZ 3PH ,460V 60HZ 3PH;

in Singapore and Malaysia ,the power supply is 415V 50HZ 3PH;

in Mexico ,the power supply is 220V 60HZ 3PH;

In USA ,the power supply is 208V 60HZ 3PH;575V 60HZ 3PH;480V 60HZ 3PH and so on

9.4 Water Pump

When you decide the capacity/tonnage of the chiller, we will recommend you the suitable pump in KW,which standard water pump is about 2 bar .If you need more high water pressure , please us when you inquiry.

9.5 Refrigerant

R22, R410A, R407C, R404A, R134A are optional choices.

R22: good cooling effect, but R22 is considered a powerful greenhouse gas, so it’s forbidden in most countries.

R410A: eco-friendly, R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan, Europe, and the United States. R-410A operates at higher pressures than other refrigerants.

R407C: a good replacement for R22, good cooling effect.

R404A: suitable for application that requires low temperature(below -10°c).

R134A: a non-flammable gas used primarily as a “high-temperature” refrigerant, suitable for air-cooled chiller working at a high ambient temperature above 50℃.

9.6 Evaporator Choose

Chillers generally have two types of evaporators: one is stainless steel+ water tank evaporator ,the other one is shell and tube evaporator.

Stainless steel plate and tank evaporator, which has a built-in water storage tank for more convenient use,so there’s no need for extra buffer tanks. This is also our standard evaporator for chiller , if you don’t have buffer tank ,we just use this evaporator for your chiller.

Shell and tube type evaporator, which requires an additional water buffer tank to connect .

Shipping Way of Industrial Glycol Chiller For Cooling Fermentation

As a professional low temperature glycol chiller supplier &exporter,we have our own shipment forwarder to arrange the shipment .Our chiller machine is with plywood packing,which prevent damage during transportation and meet export standards.There are three ways can delivery your chiller unit :

1. Ship by Air: As the chiller is with compressor ,water pump and fans ,the compressed refrigerant and oil inside the compressor is a dangerous item with the possibility of explosion , so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shipping way. After the machine arrives at your destination, you need to add refrigerant by local professionals. The airline company also request us to provide many documents to prove that the chiller not a dangerous product. The freight cost by air is very high may be higher than the cost of chiller , So By air for delivery is not the mode of transport recommended to our customer.

2. Ship by Sea: The transportation time is longer than by air , but the freight cost is cheap ,and there is no need to add refrigerant after the equipment arrives at the destination.This shipping way is the most suitable mode of transportation for you to delivery your local port.

3.If you have your own shipment container in your other supplier in China, we can help you delivery the chiller machine to your supplier in any city of China .
