Chiller maintenance plans help prevent catastrophic failures by ensuring equipment is properly monitored and serviced on a regular basis. These plans can vary based on a number of factors, including chiller type, manufacturer, geographical region, and client preference, to name a few.

Ray Humphries, area service manager for Capstone Mechanical in Waco, Texas, said the most common chiller failures he sees are not catastrophic. “They are usually very minor component failures, such as thermistors, pressure transducers, and flow switches,” he said. “These are all relatively minor parts that are both inexpensive and easy to replace, if you have them on hand. Most of these are specific to a particular chiller.”

Maintenance plans are then based upon their requirements, expectations, and willingness to properly plan and budget, says Greg Crumpton, president and founder of AirTight FaciliTech in Charlotte, North Carolina. “A research-and-development facility that doesn’t lose money if they miss an eight-hour shift without a chiller available is a lot different than a high-density data center. It really comes down to what the customers [want to pay] to ‘insure.’ Uptime isn’t cheap, but sometimes downtime can be devastating.”
