Unit 7 Closed Loop Cooling Water System - City of Ames

This project is to install a new closed loop glycol cooling system on Unit 7. Currently all of the equipment on Unit 7 that needs to be cooled (boiler feed pumps, hydrogen coolers, air heater, force draft fan bearings, and the exciter) are cooled with open loop systems from well water, cooling tower water, or City water. These waters are difficult to treat and cause equipment to get dirty quickly. This prevents a good heat exchange and higher running temperatures. A closed loop glycol system will be more economical and allow for better cooling efficiency As of February 15, 2021 no new CIP issued, this project is currently in the FY 2020-2025 CIP . Funding for this project is allotted in the city's capital improvement plan for construction Fy 2022. A firm timeline has not been established; however, construction is scheduled for Fiscal Year 2022. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available. As of July 20, 2023, no new information available
