Water-for-Injection Distribution Skid

Mueller water-for-injection (WFI) distribution skids and custom skids are tailor designed to meet the specific requirements of your application.  These equipment skids can incorporate all of the monitoring instruments and control devices for the WFI distribution system into a compact skid, which is assembled and integrated into a PLC system. 

Utilizing a system approach drastically reduces the time and cost required to assemble, start up, and validate the resulting system. These benefits are due to the ability to concurrently perform site work while fabricating and testing the system at Paul Mueller Company.
