5 tips to maintain an industrial chiller

An industrial Chillers Unit in USA is a device that represents a sizeable capital investment. It likewise contributes in a significant way to the operational costs of any facility. For many establishments, the chiller is the single biggest energy user, so maintenance is vital to ensure that it is always in a good and efficient operating condition.

Fortunately, efficiency in chiller models has steadily improved because of significant advances in refrigerants, unit design, and controls. Still, regular chiller maintenance and checkup services have become crucial more than ever. The following are effective tips and advice on maintaining and checking industrial and chillers to ensure their efficiency and quality of service.

1. Make use of operating log

The performance of industrial-type chillers must be documented daily. The comparison should be done regularly to detect any issue or problem that might crop up.

Logs are effective means in helping the operator list down a history of conditions, which can, later on, be checked and analyzed for any occurring trends. Logs are effective in giving out warnings of potential operating problems always.

2. Ensure a Leak-free Unit

Leaks are some of the significant reasons why chillers perform below their expected performance levels. If leaks are present in the unit, this can cause air and moisture to seep in and get trapped in the condenser. Consequently, it can be a cause behind its reduced efficiency and cooling capacity. Therefore, moisture must be prevented from getting inside the chiller. This can develop acids that may corrode the motor and bearing parts. Leaks also cause rusts in tubes, which negatively affect the heat transfer ability of the unit.

3. Maintain clean tubes

One issue that hinders a top-notch chiller performance is the efficiency of chiller heat transfer. Undoubtedly, the inability of a unit to transfer heat directly affects its overall performance. Effective heat transfer is maintained if operators regularly clean the unit’s condenser and evaporator tubes. While cleaning tubing in heat exchangers is laborious, doing so is a must to ensure high-efficiency performance.

4. Maintain water treatment

Chillers make use of water for efficient heat transfer. Hence, water should be adequately treated to avoid scaling, corroding, and biological growth. Closed water system chillers need a single chemical treatment of water. On the other hand, open systems require continuous and regular chemical water treatment.

To maintain an industrial chiller’s quality, operators must work with a dependable chemical-treatment expert who can offer full-service water treatment and maintenance systems for chillers.


5. Analyze refrigerant and oil

Finally, another effective tip in ensuring a well-conditioned chiller is a chemical analysis of refrigerant and oil. This procedure must be done every year to detect contamination issues even before any problem becomes serious. The research includes a spectrometric chemical checkup that identifies contaminants, like moisture, unwanted air, metals, and acids. Manufacturers of chillers offer yearly refrigerant and oil analysis to their products.
