Low Temperature Glycol Water Cooled Chiller

A glycol water chiller is a chilling system that uses a percentage of glycol mixed with water to create extremely low temperatures far beyond the freezing point of water. The two types of glycol are ethylene glycol-based or propylene glycol-based. The antifreeze nature of glycol ensures that the coolant remains in a fluid state to reach its low cooling points.

Benefits of Glycol Water Chiller

1. Safety Advantage: One of the common concerns of refrigeration systems is the fear of leaks that can raise temperatures and destroy crops. This particular factor is non-existent with glycol chillers since glycol has inhibitors that make a system resistant to corrosion, scales, and rust, which can cause leaks and damage pipes.

2. Chiller Maintenance: Adding to the safety features of a glycol chiller is its low maintenance. Glycol chillers can store products and keep them cool for long hours without the need for any form of costly maintenance. The system can last for years without falling apart or requiring maintenance while providing exceptional performance.

3. Economizer Feature: The economizer feature on glycol chillers is designed to take advantage of cold air. When the ambient temperature is correct for the chiller, a control switch turns off the compressor and uses the chilled environmental air for cooling purposes. The economizer feature blends enough of the ambient air to meet the thermostat's setpoint. This is a money-saving device built into most glycol chillers.

4. Low Temperatures: Glycol chillers operate at temperatures far below the freezing point of water, which can be controlled by altering the glycol mixture percentages. A 10% ethylene glycol mixture will freeze at 26o F, while a 60% mixture has a freezing temperature of - 60o F. The antifreeze properties of glycol ensure that the coolant remains in a continuous fluid condition.

5. Cost Savings: A glycol chiller unit can cost less than half of the cost of a self-contained refrigeration unit since it involves purchasing a single glycol chiller instead of several separate ones. The chiller compressor cools the glycol and water without the need for other components or mechanisms. Get a quote.

6. Antifreeze Qualities: The principal benefit of glycol coolants is 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.

7. 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. 

8. 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 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 water. 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.
