Are you looking to find out the right amount of glycol in your chilled water system? Glycol is an important component of a chilled water system, as it prevents freezing and corrosion. In this article, we’ll discuss why glycol is used in chilled water systems and how much is needed to ensure your system is running properly. We’ll also provide tips on how to measure and monitor the glycol levels in your system. Read on to learn more about how to maintain the proper amount of glycol in your chilled water system.
The amount of glycol in a chilled water system depends on the size and type of system. Generally, a system requires 5-20% by weight of glycol. The glycol must be of a type suitable for potable water systems and the ratio of glycol to water should be determined according to the manufacturer’s guidelines.

Glycol in Chilled Water Systems: An Overview
Chilled water systems use glycol to maintain the temperature of a liquid or refrigerant. Glycol is a type of antifreeze, which is a substance that lowers the freezing point of water and prevents it from freezing. In a chilled water system, glycol is used to prevent ice from forming and to keep the temperature of the water within a specific range. The amount of glycol used in a chilled water system varies based on the size and type of system, as well as the temperature range being maintained.
Types of Glycol Used in Chilled Water Systems
There are two main types of glycol used in chilled water systems: ethylene glycol and propylene glycol. Ethylene glycol is a colorless, odorless, and sweet-tasting liquid that is used as an antifreeze. It is the most common type of glycol used in chilled water systems and is the least expensive option. Propylene glycol is a slightly more expensive option, but it is more environmentally friendly than ethylene glycol. It has a bitter taste and is less toxic than ethylene glycol.
How Much Glycol to Use in a Chilled Water System
The amount of glycol to use in a chilled water system depends on the size and type of system, as well as the temperature range being maintained. Generally, the amount of glycol used in a chilled water system should be between 10 and 20 percent of the total volume of the system. For example, if a chilled water system is 5,000 gallons in size, the amount of glycol used should be between 500 and 1,000 gallons.

Factors That Affect the Amount of Glycol Needed
There are several factors that can affect the amount of glycol needed in a chilled water system. For example, the size of the system and the temperature range being maintained can both affect the amount of glycol needed. Additionally, the type of glycol used can also affect the amount of glycol needed. For example, ethylene glycol requires more glycol than propylene glycol to achieve the same temperature range.
Choosing the Right Glycol for a Chilled Water System
When choosing a glycol for a chilled water system, it is important to consider the type of glycol as well as the amount needed. Ethylene glycol is the most common type of glycol used in chilled water systems and is the least expensive option. However, propylene glycol is a more environmentally friendly option and is less toxic than ethylene glycol. Additionally, the amount of glycol needed should be determined based on the size and type of system, as well as the temperature range being maintained.

The effectiveness of a chilled water system is largely dependent on the amount of glycol used. Too little glycol in a chilled water system can lead to corrosion, while too much can lead to system freezing and other problems. The correct amount of glycol for a chilled water system is dependent on several factors, such as the climate, system design, and system components. Ultimately, the correct amount of glycol for a chilled water system should be determined by a qualified professional based on these factors, ensuring a safe and efficient system.
