Industrial chillers are great equipments that bring in a lot of great benefits to industries. But they’re also expensive. In fact, they may be the most expensive equipment in other companies. This is the reason why it is important to observe chiller maintenance and make sure that chillers aren’t abused. Chillers need to be taken cared of if industries want them to perform and serve them for a long period of time. But all good things must come to an end. However with industrial chillers, caution and thorough decision should be done before making a choice.
The biggest mistake in chiller usage is thinking that just because chillers, no matter how used, are still operating mean that they are still ok. Used chillers are still operating but not efficiently anymore and the overall cost for electricity charges may be more than the initial cost of actually buying a new one. However, one must think of all the factors before getting a replacement for used chillers.
A chiller’s condition is important and how old it already is. Changes have been made over the years and if the chiller started operating 10 years ago with a specific set of load, chances are they have changed as well. This may have caused an oversizing of the chiller. You can do a review of the load profile of your current building and re-evaluate the maximum cooling load that the chiller needs to meet. If it can’t be met, it’s a good sign for the chillers to be replaced but it still needs to be evaluated thoroughly.
