Trane Regasket Program for Chiller Maintenance
Ensuring Optimal Performance and Longevity of Your Cooling Systems
What is a Gasket?
A gasket is a sealing material, typically a sheet, used to prevent the leakage of liquids or gases between two mating surfaces. In HVAC systems, particularly chillers, gaskets are crucial components that maintain the integrity of the system by sealing internal parts. They are designed to be made of softer materials than the surfaces they seal, compensating for minor imperfections and ensuring a tight fit. The necessity for gaskets arises from the fact that metal surfaces are rarely perfectly flat or uniform, and different materials may be joined, requiring a barrier to prevent leaks and contamination.
The Regasket Program for Chillers
Chiller systems, especially water chillers, contain numerous gaskets. Over time, these gaskets can degrade due to operational stress, age, or environmental factors. A failure in even a single gasket can lead to significant problems, such as refrigerant leaks. For systems using refrigerants like HCFC123, such leaks can also allow air to enter the refrigerant circuit, severely impacting the chiller's performance and potentially causing long-term damage. Therefore, a proactive regasketing program is essential for maintaining system efficiency and reliability.

When to Consider Regasketing
Regular inspections are key to identifying potential issues before they become critical. For instance, using an electronic leak detector can pinpoint refrigerant leaks, often caused by degraded gaskets. Proactive replacement of worn gaskets, as part of a regasketing service, prevents minor issues from escalating into major system failures, saving time and resources.

Regasket Recommendations
To ensure continuous operation and efficiency of your chillers, Trane recommends the following maintenance schedule:
- For general chiller maintenance, it is recommended to replace gaskets every 50,000 operating hours.
- Monitor your chiller's performance. If you detect signs of leaks or notice abnormal operation, such as unusual activity from the Purge unit, it is advisable to consider regasketing.
Specific recommendations for Trane chiller models, such as the CVH* series, include:
- Economizer kit gaskets: Recommended replacement every 5 years.
- Terminal motor gaskets: Recommended replacement every 5 years.
- Suction cover O-rings: Recommended replacement every 5 years.
