What Are Closed-Loop Chillers? Closed-loop chillers are used to exchange heat from industrial or commercial applications by running coolant through a closed-loop system. These chillers use various kinds of coolant, including water, glycol and oil-based coolants. Many processes today rely on chiller systems that are closed-loop. For example, data servers run by large tech companies rely on air conditioning and water chillers to draw away heat generated by powerful electronic equipment. Both the air conditioner and water chillers are closed-loop systems due to the fact that they recycle the air and water used to extract heat. The air conditioner reuses […]
