Chemi-Con Materials, Corporation – Numerous Improvements

Dahlgren Industrial as participated in numerous improvements to the Chemi-Con Materials Corporation facility in Moses Lake, WA since 2011.  This firm is a wholly owned subsidiary of Japan Based Nippon Chemi-Con Corporation.  At this facility, they manufacture energy intensive materials that are used throughout the world for manufacturing high voltage electronic capacitors.  Over the years, Dahlgren has worked with their Japan based and Moses Lake based engineering and management personnel to both plan and execute construction projects.  Some of those projects are listed as follows:


  • 2011    TDS Evaporator Improvements:
    • Construction New Building and install a new Packaged Evaporator as procured by client. This project involved the complete design of the building as well as mechanical and electrical utilities.


  • 2013    Pump Safety Valve Implementation:
    • In an effort to improve the safety conditions for Chemi-Con employees, Dahlgren was contracted to supply and install large isolation valves within one of evaporator systems at the plant.


  • 2014    East Bay Air Cooled Heat Exchanger Units Installation:
    • For this project, Dahlgren Industrial was contracted to Design, Supply and Install two large Air-Cooled Heat Exchanger Units to support additional cooling demand in the facility.  This project included the complete design as well as procurement and installation of this equipment.  A control system was also designed and supplied and integrated into the plant’s other monitoring systems.


  • 2015    New Boric Evaporator Installation:
    • For this project, Dahlgren Industrial was contracted to install a new Packaged Evaporator as procured by client. This equipment was installed within an existing building however, numerous improvements were required.  This project also included a backup generator system to operate external critical cooling processes.


  • 2017    Environmental Modifications:
    • This project occurred during the plants regularly scheduled summer shutdown.  During this time, Dahlgren helped to improve several features of the plant’s environmental treatment processes.  Some process tanks were removed and relocated.  Concrete containment areas were repaired and improved.  Finally, new floor coating systems were applied.


  • 2018    Miscellaneous Projects:
    • Throughout this year, we participated in several projects for this client.  Those projects include:
      • Design, Supply and Install a complete industrial oven system
      • Repair Air Cooled Heat Exchanger bundles damaged during freezing
      • Replace Air Cooled Heat Exchanger bundles damaged during freezing
      • The oven project created a significant capacity increase to the facility and required urgent completion to meet production demands.   Dahlgren’s work included the procurement of ovens as well at participation with design, fabrication and delivery of the ovens.  Dahlgren rigged and set the equipment when they were delivered and completed the installation of the utility connections.  The exhaust systems were significant.
      • Dahlgren repaired 2 ea. Air Cooled Heat Exchanger bundles on an emergency basis.  Dahlgren mechanics traced out the numerous leaks and patched and test them.
      • Dahlgren removed and replaced the 1 ea. Air Cooled Heat Exchanger bundle that could not be repaired.  This work included rigging and removing the old bundle and replacing the new bundle.
