Glycol Systems

Glycol is commonly used in closed-loop HVAC systems which provide heating and cooling. The glycol solution is circulated through the system’s pipes, carrying thermal energy to and from the heat exchangers. Although glycol is an efficient and reliable heat transfer fluid, it is not immune to failures that can cause costly downtime and equipment damage. […]

Glycol use in HVAC systems is common practice for facilities in the Northeast, and keeping them running efficiently requires specialized expertise. For chief engineers, mechanical contractors, and building managers overseeing these systems, lack of oversight and maintenance could result in tenant complaints, costly repairs, or even mechanical failures. This article details why it’s essential to […]

For building managers and property owners, managing a cooling system isn’t just about ensuring comfortable temperatures for occupants—it’s also about safety. During winter, a key component often used in HVAC systems is propylene glycol, a compound that aids in heat transfer and prevents freezing. While propylene glycol provides essential benefits, it’s important to maintain the […]

There are many types of glycols, but the ones common in heating and cooling systems are ethylene glycol and propylene glycol. Glycol is used in the winter as an antifreeze due to its ability to intervene with hydrogen bonding, lowering the freezing point of water. In HVAC systems, glycols are used with water to create […]

Maintaining a glycol water system is crucial for ensuring the efficient operation of your HVAC system. Glycol, a type of antifreeze, is added to the water in these systems to prevent freezing and overheating. Glycol however, requires a certain level of maintenance and you cannot just “set it and forget it”. Here’s how to maintain […]

Many commercial buildings use closed loop systems as part of their HVAC operation. In the winter, it is important to protect these systems from exposure to the cold. To prevent freezing, glycol is normally added to these loops to maintain operation. However, simply adding glycol to the system once won’t provide permanent protection, and the […]

If you operate HVAC systems that require the addition of glycol, you may not have realized that the glycol content needs regular testing. Failure to properly test your system’s glycol can result in overlooking signs that your system could have issues or could be failing. Lab testing is the solution to this problem. Consistent testing […]

If you operate a system that benefits from being cooled, such as a wine storage room or a cooling tower, you may have looked into your options for chillers. Glycol systems are a common choice, because they are easy to maintain and effective in keeping things cool without the risk of freezing. However, if you […]

If you are in charge of temperature regulation in a building or as part of your livelihood, you have likely heard of glycol systems. These systems use a mixture of glycol and water to prevent freezing and keep things chilled, such as important machinery or the fermenting and storage equipment for wine. However, using a […]
