Tubes are the main path for heat transfer in chillers and can be largely responsible for the performance of your industrial chiller. Contaminants and impurities can increase thermal resistance. This would reduce heat transfer efficiency as the resistance would affect the consistencies in approach temperatures in the chiller. It is important to brush these tubes at least once per year. With a strong monitoring system, you’ll be able to see problems before they occur. Giving you the opportunity to clean the tubes before they become too much of a problem.
