Tips for Commercial Chiller Repair & Maintenance
Commercial chiller repair is an important part of the responsibilities of any chiller owner. There are several causes that can lead to the breakdown of an industrial chiller, but they can be prevented by following a few simple steps.
Perform routine maintenance every quarter. Your chiller manufacturer should provide you with a chiller inspection form as a guide. If available, consider joining a customer’s preventative maintenance program. Always hire a licensed company to handle maintenance and repairs, and keep a record of all maintenance and repairs as a reference for future needs.
Inspect the heat transfer fluid to ensure it is free of debris and has the appropriate rating for the ambient conditions and process fluid temperatures. Then, check the “Y” strainer to make sure it is clean and not obstructing the flow of heat transfer fluid.
Next, examine the condenser coils for any dirt or debris buildup. A clean coil allows for better airflow, which promotes more efficient heat transfer. Measure the condenser and evaporator pressures.
Inspect the wiring and connections to ensure they are secure and tight. Loose wires can develop over time and cause random chiller faults.
Verify that the chiller safety switches are functioning properly to ensure the chiller is protected in the event of a fault. Additionally, inspect the fan blade, shaft, bearing, and motor for any signs of wear to ensure proper airflow for heat removal. Always pay attention to any unusual noises or vibrations.
Thoroughly inspect and clean the electrical contacts. Check the chiller pump to ensure there are no leaks in the pump seals or bearings, and inspect the piping to ensure there are no fluid leaks at any contact points.
Lastly, make sure the Schrader valve is properly seated and the cap is tightly secured.
