Chiller Maintenance: Repairing or Replacing a Broken Chiller

NSC AdminUncategorized

As much as we’d love technology to run at maximum efficiency 100% of the time, regular wear and tear can lead to malfunctions. If your business owns or regularly uses a chiller unit, it could be helpful to familiarize yourself with these chiller repairing and maintenance steps.

When it comes to water chiller repair and maintenance, it is necessary to know and understand how chiller systems work. Here are a few helpful tips that can help keep your chiller running efficiently:

Chiller Maintenance Guide

1. Track and Monitor Daily Operations Log

A daily operations log provides supporting data to help isolate problems and fix inefficiencies faster.  Details under the log should include flow rates, operating temperatures, and other crucial information. Keeping a detailed log takes just a few minutes a day and could be the key you need to get things up and running again should a problem arise.

2.Use Regular Water Treatments

There are many different types of chillers used in different situations, but the most common are water chillers, or water-cooled chillers. Water in the units must be frequently treated to prevent corrosion, scale accumulation, and algae growth. For closed water systems use regular chemical treatments. Filters should be cleaned every three months to prevent contaminant buildup.

3. Immediately Tend to Leaks

Small leaks in your chiller system can lead to more serious issues. Unwanted moisture could contribute to the formation of corrosive acids. Additionally, moisture could cause chiller parts to rust and stop working properly. Carefully check your unit at least once quarterly for leaks.

4. Clean System Tubes

Overall system productivity depends upon the efficiency of heat transfer in the evaporator and condenser tubes. Keeping these tubes clean will help keep your chiller running smoothly. Cleanings are done through brushing or applying chemicals to remove algae and scale accumulation.

5. Regularly Conduct Oil and Refrigerant Analysis

Regularly analyzing the oil and refrigerant within your system can help prevent more complicated issues. Consistent refrigerant analysis can help detect contamination issues. Oil analysis can expose underlying problems such as problems with compressor wear or excess moisture content in the oil.

When chiller units malfunction or breakdown, try following these common chiller problems solutions:

  • If your pump runs irregularly, check that all valves are open to the chiller. Next, check for possible debris entering the pump. If everything looks clean, check that the pressure is within the normal range. If all looks well there, there could be a possible problem with the pump component that requires professional attention.
  • If there’s an irregularity with the switch contact, you can use a simple multimeter to check the contacts of the switch.

  • Additional issues will likely require professional attention. If you’ve been experiencing issues with your chiller unit, give us a call at (866) 826-2993.
