Glycol Chillers

Glycol Chiller

Lowest Temperature Chillers On The Market

At Universal Chilling Systems, we aim to provide affordable cooling solutions to a wide range of industries by offering both Standard Packaged units and customizable units built to your specifications. 

​

We have designed our Air Cooled Glycol Chiller to fit a range of Low Temperature Applications. Our units are rated to provide you a set cooling capacity at 5°F, that is 15 degrees lower than other chillers on the market.

​

We understand that not every application requires such low temperature and thus we have provided a Cooling Capacity by Leaving Fluid Temperature Charts for our most popular models.

​

Glycol is recommended for all units when operating temperatures reach below 41 °F (5 °C).

Advantages of Air Cooled Glycol Chillers

 

Antifreeze Qualities:

The principal benefit of glycol coolants are their anti-freeze qualities. Compared to pure water, which freezes at 32 °F (0 °C), 30% ethylene glycol freezes at 6.8 °F (-14 °C).  Due to their low freezing points, glycol mixes are perfect for chilling objects below the freezing point of water.

 

Quick Heat Removal:

Despite having a lower heat capacity than water (glycol can be heated more easily than water per kilogram), a mixture of glycol and water can remove heat more quickly than pure water due to the higher temperature differential. Applications where the chiller must swiftly remove significant amounts of heat are better suited for the glycol combinations. 

 

Long Lasting, Low Maintenance:

In addition to offering excellent heat transfer parameters, glycol prevents corrosion and algae or bacteria formation in heat transfer equipment. They accommodate the narrowest temperature ranges, as tight as +/- 1°. They last longer and require less maintenance than alternatives.

Glycol Chiller Systems

 

Glycol chilling is a cooling technology that allows producers to dramatically lower the temperature of the product over a short period, depending on the production needs.

 

A glycol chiller funnels a glycol-water coolant mixture from the refrigeration unit through thermal heat exchanger piping, absorbing heat from the industrial process and warming the coolant. Next, the warmed coolant returns to the refrigeration unit to repeat the cooling process.

 

Glycol Chillers FAQs

​

  • What does an air-cooled chiller do?

Air-cooled chillers are commercial and industrial facilities most commonly used in refrigeration systems. They function by transmitting heat that has been absorbed by processed water. They are to be used in areas where heat discharge is not a serious issue.

​

  • Do air-cooled chillers use glycol?

No: instead, the heat from processed water is absorbed by an air-cooled chiller to produce cooling. The chiller's evaporator is used to remove heat from the water. After use, the water in the air handler system warms up and is redirected to the chiller.

​

  • What is a glycol chiller system?

A glycol chiller is a cooling technology commonly used to refrigerate various liquids, such as alcohol. Using a chiller allows producers to lower the temperature of the product dramatically over a short period, depending on the production needs.

​

  • How does a glycol system work?

A glycol chiller funnels a glycol-water coolant mixture from the refrigeration unit through thermal heat exchanger piping, absorbing heat from the industrial process and warming the coolant. Next, the warmed coolant returns to the refrigeration unit to repeat the cooling process.

 

  • Why do I need a glycol chiller?

A glycol chiller provides many benefits compared to other systems that use ice or purified water to cool industrial operations, notably in food applications. For example, it preserves the quality of frozen foods, leading to better taste by maintaining a consistent cooling temperature.

 

  • How big of a glycol chiller do I need?

The chiller size is typically based on tonnage. Our total heat load is in BTU/HR; to convert that to tons, simply divide the Total BTU/HR by 12,000 BTU. This basic calculation helps to determine the size of the chiller.

 

  • Is glycol better than water?

The freezing point of pure glycol, or a mixture of glycol and water, is substantially lower than pure water. By implication, glycol-based chillers are better suited for low-temp environments. Conversely, water can retain and conduct heat from an associated process better than a glycol mixture.

 

  • Can glycol be used for cooling? What are the advantages?

The main advantage of glycol coolants is their antifreeze properties. Glycol mixes are perfect for cooling things since they have a freezing point below that of water. Thirty percent of ethylene glycol freezes at 6.8 °F (-14 °C), while pure water freezes at 32 °F (0 °C).

 

  • How often should glycol be changed?

We advise mixing distilled water and 100 percent USP propylene glycol at a ratio of 1 part glycol to 2 parts waters. Inhibited glycol is OK but not necessary. We advise replacing the glycol solution around once a year as a suitable maintenance procedure for your glycol chiller.
