Industrial chillers remove unwanted heat from machinery and processes, lowering the temperature and improving the quality of output. Whereas a commercial chiller is designed to lower a room’s temperature, an industrial chiller can lower temperatures by dozens of degrees. Proper maintenance is essential to keep the chillers operational for as long as possible. Water-cooled chillers require their own type of maintenance, while air-cooled chillers typically do not.

If you have an industrial chiller, you have to ensure that it gets the proper maintenance. This blog post will share a maintenance checklist to ensure you are taking the right steps to ensure your chillers stay in service for longer. 

Industrial Chiller Preventive Maintenance Checklist

1 – Maintain your Daily Logs

Record all of your daily maintenance records from your chillers in a log. These logs allow you to always know what you did the day before. With good logs, it will become much easier for you to keep track of what you have done and what you are planning to do.

2 – Preventative Maintenance

Preventative maintenance is an important part of the chillers’ maintenance. Usually weekly or biweekly, you should be doing these preventative maintenance tasks. Doing them will help ensure that your chillers operate at peak performance.

3 – Monitor your Chiller Coolant

Chiller coolant is the liquid that transfers energy from the chillers to the refrigeration system. Make sure that the levels of the coolant are at the levels specified on the system for optimal performance. Also, make sure that your chiller coolant does not have any debris or impurities in it. If it does, drain the system and replace it.

4 – Inspect the Condenser Water Loops

The condenser water loops are what transfer the heat from the condenser coils to the condenser water. Inspect them for cracks, leaks, and other damages. If there are any issues, you need to replace the part.

5 – Flush the Chiller System

Flushing your chiller system is the practice of draining and replacing the coolant of your chillers. This helps keep the system clean, removes corrosion and other damaging particles out of the system, and helps prevent any damage from being done to the system.

6 – Perform a Full Plant Shutdown

While plant shutdowns should only happen as often as needed, there are times when you may need to do them. For example, if you need to install new parts or update any of the components in your chillers, you will need to plant shutdown. Allows you to perform all the tasks needed to add new features and remove the old ones.


Industrial chillers provide many benefits to a manufacturing process, helping to lower the temperature, remove heat from machinery and processes, and improve the quality of output. With proper maintenance, industrial chillers can operate longer and more efficiently. Following this maintenance checklist will make sure your chillers are in top shape and will continue to provide the needed cooling benefits to your operation.

For the best results, you need to watch out for the maintenance and make sure that the chillers do not get damaged by any of the other maintenance tasks.
