Laboratory refrigerated circulator (water chiller) are used in a variety of applications where chilled water or liquid are circulated through process equipment. Commonly used to cool products and machinery, water chiller is used in a multitude of different applications including injection molding, tool and die cutting, food and beverage, chemicals, lasers, machine tool, semi-conductors and more.
The function of a chiller is to move heat from one location (usually process equipment or product) to another place (usually the air outside the manufacturing facility). It is very common to use water or a water/glycol solution to transfer heat to and from the chiller which may require reservoir and pumping system. In most process cooling applications, a pumping system circulates cool water solution from chiller to the process. This cool fluid removes heat from the process and warm fluid returns to the chiller. The process water is the means by which heat transfers from the process to the chiller. They work on the basic principle of compression and phase-change of the refrigerant from a liquid to a gas and back to a liquid. This process of heating and cooling the refrigerant and changing it from a gas to a liquid and back again is the refrigeration cycle.
Laboratory refrigerated circulator is very useful for many common heat removal applications, including laser etching, AA furnaces, ICP, rotary evaporators, vacuum systems, reaction vessels, plasma etching, and condenser cooling.
