The prime source of cooling for most facilities is a centrifugal water chiller. Like all electrical/mechanical equipment, it is subject to wear and tear over the years. An active preventive maintenance program will definitely slow the process but nonetheless, internal wear continues.

A major overhaul of your system, in addition to a preventative maintenance program, protects your investment even further. During a major overhaul, all gaskets and atmospheric seals, as well as any worn parts in the compressor or motor, are replaced.

How often should you overhaul your equipment?

The recommended interval is somewhere between 35,000 to 50,000 hours or sooner if predictive maintenance such as oil analysis or vibration analysis indicates a need. For the ‘average’ installation, the ten-year overhaul cycle or every 100,000 hours seems to work best. If the machine must operate under more severe conditions, such as frequent cycling or inadequate maintenance, then a more frequent interval should be considered.  

There are tangible benefits to be realized from an overhaul. These benefits can often outweigh the overhaul cost. Some of the benefits include:

  • Longer equipment life
  • Better efficiency
  • Reduced downtime and fewer operational interruptions
  • The overhaul process will incorporate manufacturer’s upgrades and improvements to add to the reliability of the machine
