What is the Expected Lifespan of a Chiller?
At Applied Thermal Control, we understand that our customers rely on our chillers to support critical processes and applications, whether in research laboratories, manufacturing environments, or industrial facilities. When you invest in a chiller, you’re investing in the reliability and stability of your operation.
Naturally, a common question we’re asked is: How long can I expect my chiller to last?
Typical Lifespan of a Chiller
A properly maintained recirculating chiller will generally last 8 to 15 years, depending on several key factors. Some units even operate effectively beyond 15 years, but longevity is highly influenced by:
Cooler, cleaner environments are ideal. High ambient temperatures can force the chiller to work harder, accelerating wear on components. Dust, humidity, and airborne chemicals can also degrade internal parts and electronics over time.
Regular preventative maintenance is critical. Systems that are neglected or only serviced when a problem arises are more likely to suffer premature failure.
Poor water quality can cause scale, corrosion, and biological fouling, all of which can severely impact the chiller’s internal systems and reduce efficiency.
High-quality chillers use premium-grade components designed for durability and long service life.
Selecting a unit with slightly more capacity than required can reduce strain and often results in a longer lifespan.
Maximising Your Chiller's Lifespan: Routine Preventative Maintenance
Regular maintenance is essential for keeping your chiller operating efficiently and extending its service life. This includes checking and cleaning air and fluid filters to maintain proper airflow and fluid circulation. Condenser coils should be cleaned periodically to remove dust and debris that restrict heat transfer. Pumps, motors and coils should be inspected for signs of wear, noise or vibration, allowing you to address issues before they lead to costly failures.
Additionally, routine electrical inspections help to ensure connections remain secure and free from corrosion or overheating. Some units include integrated filters – make sure to check, clean or replace them as part of your regular maintenance schedule.
Maximising Your Chiller's Lifespan: Fluid Quality Management
Proper fluid management plays a major role in the health of your chiller. Always use the correct heat transfer fluid mixtures, such as Hexid, as recommended in your user manual. These heat transfer fluids help to prevent corrosion, biological growth, and freezing.
Over time, even the best fluids degrade or become contaminated, so regular fluid changes are necessary to maintain system efficiency. Monitoring the quality of your cooling water is also vital – using deionised or properly treated water reduces the risk of scale formation and internal corrosion.
Maximising Your Chiller's Lifespan: Environmental Controls
The environment in which your chiller operates has a significant impact on its lifespan. Place the unit in a location where the ambient temperature is controlled and avoid exposure to direct sunlight or nearby heat sources. Adequate ventilation is critical – ensure that there is enough free space around the chiller for air to flow freely.
In more challenging environments, such as those with high levels of dust or chemical vapours, consider using additional protective measures like enclosures or enhanced filtration systems to safeguard the internal components.
Maximising Your Chiller's Lifespan: Operational Best Practices
How you operate your chiller day-to-day can have lasting effects. Avoid overloading the system beyond its design specifications, as this puts unnecessary strain on components and can lead to premature wear. Always follow the recommended start-up and shutdown procedures to prevent thermal shocks.
ATC chillers are designed to run 24/7 – leaving them on continuously is actually beneficial and promotes stability, reducing thermal cycling and extending component life.
Additionally, monitoring key performance indicators, such as outlet fluid temperature and system pressure, can help you detect early warning signs of potential issues before they develop into major problems.
Maximising Your Chiller's Lifespan: Professional Servicing
Scheduling regular professional servicing is an excellent way to extend your chiller’s life. An annual service visit allows technicians to perform detailed inspections, conduct performance diagnostics, and fine-tune the system.
ATC also offers service contracts that provide scheduled maintenance and priority support, giving you peace of mind that your chiller is always maintained to the highest standards.
Signs That a Chiller May Need Replacement
Despite the best maintenance practices, all equipment ages. Signs that it may be time to consider a replacement include:
