Prepare Your Chiller for Summer
Be sure to maintain your chiller before the summer heat arrives.
BlueField is Dubai’s most experienced and trusted name in chiller maintenance. We empower our technicians with the best guidance and training to deliver exceptional results. Over time, every piece of equipment experiences normal wear and tear, making thorough knowledge and regular maintenance of your commercial or industrial chiller essential.
Proper maintenance ensures your chiller’s longevity and efficiency, which can lead to significant cost savings for your business. A well-maintained chiller keeps both your equipment and your energy bills in check. By following our chiller maintenance checklist, you can reduce breakdowns and downtime—protecting your operations from costly disruptions.
The following tips will help you maintain your industrial chiller and safeguard your business against major failures.
Chiller Maintenance Checklist
To keep your chiller running efficiently, it’s essential to track routine activities and system performance. Maintain a detailed log of important data like flow rates, temperatures, pressures, and fluid levels. Downloadable log sheets or automated remote monitoring systems can make this process easier and more accurate.
Include these items in your general maintenance routine:
Record refrigerant and oil levels
Inspect the fan control system
Monitor the evaporator water temperature differential
Measure the condenser fan motor’s voltage and amperage, if needed
Check evaporator water flow
Monitor pressures in both the evaporator and condenser
Test the controls to ensure all functions are working properly
Proper chiller maintenance ensures long-term efficiency and reliability. Focus on these key tasks:
Tubes are essential for heat transfer in chillers, but dirt and impurities can build up, reducing efficiency. Brush and clean the tubes at least once a year to prevent blockages and maintain optimal heat exchange. A strong monitoring system can alert you to problems early, so you can act before issues escalate.
Maintaining clean condenser water helps prevent scale and corrosion, which can decrease chiller efficiency and raise pressure levels. Change filters regularly and use periodic chemical treatments to keep the water pure. This supports smooth heat transfer and stable operation.
After the first year of operating a new chiller, change the oil and filter. Regular oil analysis will help you determine the ideal frequency for future oil changes. We recommend an annual spectrometric chemical examination to spot issues like water content or particle contamination before they cause problems.
For low-pressure chillers, regularly purge the system to remove non-condensable gases such as air and moisture. These gases can accumulate in the evaporator, especially in vacuum conditions, reducing system performance. Purging helps keep pressure levels optimal and protects the system.
A common issue with chiller ACs is inadequate voltage supply. If the unit doesn’t receive the correct voltage, it may not achieve the desired cooling temperature.
There are two main types of chillers: air-cooled chillers and water-cooled chillers. Each type is suited to different building needs and operating conditions.
Chillers typically use high-quality mineral or synthetic oils designed for refrigeration compressors. The specific type depends on the manufacturer’s recommendations and the type of refrigerant used.
Chillers are used to provide efficient cooling in large commercial or industrial facilities by circulating chilled water or air throughout the building.
Most modern chillers operate on electricity for efficiency and reliability. However, in some specialized applications, gas-powered chillers may be used.
