Any piece of equipment will experience general wear and tear over time. This is even more of a reason to be well acquainted with your chiller. Much of its maintenance is similar to boiler maintenance and is no less important. Even if the specific means of maintaining aren’t the same, the reasons are. A happy chiller makes for a happy bill. Reducing equipment malfunctions and repairing downtimes through proper chiller maintenance can be an effective means of lowering costs in your operations. Below are a few ways to keep your chiller up to par, while saving your company from disastrous chiller malfunctions.

Daily Log/Maintenance Schedule

Tracking daily operations is half the battle when it comes to maintenance. Keeping a detailed log is the most efficient means of understanding how your chiller is doing. These logs should include necessary information like flow rates, operating temperatures, pressures, and fluid levels. There are many downloadable log sheets to keep these numbers up to date. But the maintenance world is doing its part in evolving with technology as well. Remote monitoring systems are very popular in supporting daily logs on machinery. It requires less time and can update as frequently as necessary since it is often an automated system. Many times, remote monitoring systems can automate insight reports as well for real-time diagnostics on your chillers.

Keeping Tubes Clean

Tubes are the main path for heat transfer in chillers and can be largely responsible for the performance of your chiller. Contaminants and impurities can increase thermal resistance. This would reduce heat transfer efficiency as the resistance would affect the consistencies in approach temperatures in the chiller. It is important to brush these tubes at least once per year. With a strong monitoring system, you’ll be able to see problems before they occur, having the opportunity to clean the tubes before they become too much of a problem.

Treat Condenser Water

Keeping the condenser water clean is important for both boilers and chillers for many of the same reasons. Corrosion and scaling both reduce efficiency. Both of which, build up over time if the water is not well-treated. Untreated can result in higher condenser pressures, impeded heat transfers and inconsistencies in water temperature and water flow. Regular chemical treatments can help keep the water clean and filters should be replaced often.

Analyze Compressor Oil

If you’re working with a new chiller, it is standard practice to do an oil and filter change after the first year and analyze that oil to determine the frequency of future oil changes. The dirtier, the more frequently your system will likely require a change. It is also recommended to do a spectrometric chemical analysis of this oil once a year to help acquaint yourself with your system and its potential issues. Learning how to address various problems, from high water content to the size of the particles contaminating the oil, can be invaluable. Also worth noting, there are many chillers that are currently offered that have completely eliminated oil from the equation, thus lowering potential maintenance costs.
