![]() GOODWAY CHILLER TUBE CLEANER FREECondenser tubes should be brush-cleaned at least annually to keep them free of contaminants. ![]() It’s fouling agents like these that make chiller tube cleaning so imperative to energy efficiency. The more a chiller becomes fouled, the more energy (and cost) it will consume. Fouling occurs gradually over time, depending on the quality and temperature of the water used. These contaminants accumulate on the water side of transfer surfaces in both closed- and open-loop systems. Contaminants, such as minerals, scale, mud, algae and other impurities, increase thermal resistance and reduce overall performance. Given the fact that a chiller typically can have several miles of tubing making up the condenser and evaporator, proper tube cleaning makes sense as way to keep chiller tubes running as efficiently as possible.Ĭhiller efficiency declines rapidly when tubes become fouled. While there are several factors that can affect chiller efficiency, cleanliness of heat transfer surfaces is often the largest single factor. Factor in fouled tubes, leaking refrigerant, changes in water temperature and several other variables, and operating costs can escalate quickly. While chiller efficiencies have improved significantly in recent years, new high-tech chillers often have narrower tolerances, making constant maintenance more crucial than ever for keeping them operating at peak performance. ![]() As energy prices increase, finding ways to generate significant energy savings through better chiller efficiency will be integral to keeping costs down. Department of Energy estimates that chillers use approximately 20 percent of the total electrical power generated in North America, and they expend up to 30 percent in additional energy due to inefficiencies and poor maintenance. ![]()
