If your process requires close temperature control, a chiller with a closed-loop cooling system is one way to cool it.
A properly designed refrigerated liquid chiller offers the ability to easily provide close temperature control of the process coolant. Temperature tolerances of +/-1oF (+/-0.56oC) are possible. Close temperature control would be desirable in applications where thermal growth of a part, die or tool could cause tolerances to change, resulting in defective products. Examples of manufacturing operations or processes that require close temperature control include:
