Tips for Maintaining and Taking Care of a Glycol Chiller

Various industries rely on glycol chillers for cooling. A glycol-based coolant allows for more consistent cooling temperatures, protecting perishable items such as refrigerated food from spoilage. But, of course, you can’t expect the system to function properly if you don’t take care of it.

So, how do you ensure your glycol chiller is in tip-top shape? Here are some important maintenance tips to remember:

·         Check the chiller daily.

Industrial chiller maintenance can be tedious, but it’s necessary to prevent damage and maximize efficiency. It’s best to track the system’s operations daily, collecting vital information about its temperature, pressure, fluid levels, flow rates, and more.

This way, you can ensure that the chiller is functioning correctly on any given day, and you will easily notice discrepancies in your data in case of damage or malfunction.

·         Keep the chiller clean.

Thermal resistance can decrease the efficiency of your chiller. Because of this, you must clean the system’s tubes regularly, eliminating any sign of mud, algae, mineral buildup, and other debris. Doing this once a year is more than enough; however, if your chiller runs 24/7, consider a more frequent cleaning schedule.

·         Measure your glycol concentrations.

If your chiller runs on a glycol-based coolant, measure its glycol concentration and ensure everything is below freezing point. Otherwise, the chiller could freeze during normal operation, restricting airflow and possibly damaging your evaporator.

For water-cooled chillers, make sure the chilled water flow rate is within the 3 ft/s to 12 ft/s range. This prevents the flow from causing vibration and tube erosion.

·         Create a checklist.

Finally, you should ensure that all parts of your chiller are working correctly. To make this step easier, you can create a checklist. Your list must include examining the safety and sensor calibrations, electrical connections to and from the system, motor cooling air vents, shaft seal, and electrical motor winds.

In addition, you can create a checklist of predictive maintenance analyses for your system, investigating parameters such as vibration, corrosion, and laser shaft alignment.

Looking for more ways to increase the longevity of your glycol chiller? Don’t forget to invest in a high-quality system from top manufacturing companies! Top-of-the-line industrial cooling systems are made with the best materials and technology, ensuring they can handle your specific cooling requirements.

The Basic Usage of Water-Cooled Screw Chiller

Water-cooled chillers eliminate heat by dissipating heat outside the system, making them practical for a wide range of industrial and commercial structures and projects. There are many types of chillers available today, and one of them is the  water-cooled screw chiller , which uses a screw compressor as its cooling unit. Newer versions of water-cooled screw chillers operate quietly and are more compact. Their optimum design and configuration ensure superior performance and reliability. Reputable manufacturers and suppliers can help you select the right model that suits your operations and cooling needs. Applications The  water-cooled screw chiller  suits various applications with its cooling capacity range from 105 KW to 3160 KW and temperatures from 5 to 30 degrees Celsius. It is common in medium to large-scale structures and operations, like airports, hospitals, shopping malls, industrial workshops, manufacturing plants, and residential buildings. It’s also ideal...

Harnessing the Power of Air: Exploring the Working Principle of Air-Cooled Chillers

  Process cooling varies across industries, depending on specific equipment and applications. One type of process cooling equipment is the air-cooled chiller. This refrigeration system cools fluids and operates in conjunction with a facility's air handler system. Unlike systems that use cooling towers, air-cooled chillers rely on fans to expel heat from the building, enhancing their versatility for various operational scales, from small setups to large venues like outdoor malls and theme parks. An air-cooled chiller consists of four key components—a condenser, compressor, evaporator, and expansion valve. Despite housing these complex components, air-cooled chillers are designed to be compact, which makes them easy to install and maintain. Their portability is a significant advantage, allowing for quick setup in emergency situations or at large events. The simplicity of their structure also makes air-cooled chillers easier to operate compared to their water-cooled counterparts. ...
