Patent number: 8117703Abstract: A modular chemical delivery system is designed to be readily convertible from use with a warewashing system to use with a laundry system, or vice-versa, merely by the replacement of one chip in the controller of the system. The dispensing system is also readily expandable by adding additional satellite pumps in order to inject additional chemicals into a single washing unit, and/or to supply chemicals to additional washing units. Plug and play technology is used so that control intelligence can be distributed from the main system controller to satellite controllers, and so that additional satellite units may be readily added, identified, and properly integrated into the dispensing system.Type: GrantFiled: September 29, 2009Date of Patent: February 21, 2012Assignee: Knight, LLC.Inventors: Stephen A.
