Cool Glycol chiller fluids are important for keeping a lot of machines under control. This makes them work longer and last better. Yide understands how important it is to balance these fluids. The way these chillers operate is by circulating cold fluid through a unit that removes heat. But the fluid can degrade with time, so you do have to replace it occasionally. It’s equally important to know when and how to change out that fluid. This blog will walk you through determining the correct glycol concentration and provide some best practices for changing our your glycol cooler chiller fluid.
What is the Right Glycol Concentration for Cooled Water Systems?
To nail the correct concentration, you can utilize simple devices such as a hydrometer. This apparatus checks the density of a fluid and lets you know how much industrial glycol chiller is inside it. If your plant is operating in colder weather, you may prefer a higher concentration of glycol. Most companies use a 30-50% glycol blend for good cooling without freezing. It’s also important what kind of glycol you use. There are two typical varieties: ethylene glycol and propylene glycol. Propylene glycol is more suitable than ethylene glycol for food-related systems.
What are The Best Practices for Glycol Chiller Fluid Changes?
First, shut off the chiller and let it cool down. Then, the old glycol can be carefully drained into an approved container. Be sure to wear safety equipment like gloves and goggles. Once you’ve drained out the old fluid, it’s also a good idea to flush the system with water and use up any of your old fluid in that process. This is to clean all the build-up gunk, so it doesn't interfere with the new fluid. With the system clean, it’s time to fill it up with that new glycol chiller unit mixture. Focus on the concentration and be cautious of it, following all the rules we have just mentioned.
How frequently do I need to change out my glycol chiller fluid to remain as efficient as possible?
Glycol chiller fluids are critical in the cooling of a number of machines and buildings, such as an ice rink or one of those huge warehouses. Your glycol chiller only operates as well as the fluid inside it – if it is dirty, contaminated, or just old then you are not getting the full performance. But how frequently do we have to replace this fluid to maintain that smooth operation? The consensus among many experts, is that long-life (glycol) fluid should be changed every 1 to 2 years.
How Do I Know When it’s Time to Replace my Glycol Fluid?
Sometimes it is not just about the schedule. You can also be on the lookout for signs that your glycol chiller fluid needs to be changed. One of the early signs is a fluid color change. If it appears darker or cloudy rather than clear, it may contain dirt or oil and you might want to consider a change soon. Another indicator to look for is if your cooler is making some unnatural sounds that it didn’t use to.
