DownloadButtonProcess Chilled Water Systems (PCW) are compact, skid mounted systems that circulate process water at a consistent temperature and pressure to the application’s point of use and back, allowing for more efficient and stable use of water-cooled machines, equipment and instruments. Many process tools, particularly in the semiconductor and solar industries, generate heat during their use. This heat must be removed from the process on a continuous basis during tool operation.

Wastech’s PCW systems continuously remove the process heat with heat exchangers as well as filter the cooling water being circulated. The process tools also require the water at a consistent pressure which is accomplished with precise control of the process pumps located on the Wastech PCW system skids. The systems can either be completely closed loop systems or they can be open systems which utilize a holding tank. Wastech designs and fabricates both types utilizing high efficiency pumps, high quality equipment and instrumentation, and precise process control. The advantage of a skid mounted system is that the PCW is provided as a single turn key system which requires minimal installation cost.
