A re-circulating chiller is a type of cooling system commonly used in laboratory settings and industrial processes where precise temperature control is required. It works by circulating a coolant, typically water or a water-based solution, through a closed loop system to remove heat from a process or equipment.Re-circulating chillers are essential in various applications such as laser systems, medical devices, analytical instrumentation, and semiconductor manufacturing, where maintaining stable temperatures is critical for accurate results and equipment longevity.
