Presentation: Judicial Center Chiller Replacement (FE Moran)
B.
ITD/BLD Exec. Dir. Fahnestock introduced the representatives from F.E. Moran.
He stated that an evaluation has been done on the County's chillers. Instead of
rebuilding 30+ year old chillers, they will be requesting to replace them with the
Air Cooled Chiller Plant.
F.E. Moran Representative, Dan Petrow, provided a presentation on F.E. Moran
Mechanical Services: Kane County Chiller Project. Mr. Petrow introduced
himself, along with F.E. Moran's Vice President, Kevin Denzel, and Account
Manager, Drew Petrow. He stated that the F.E. Moran Service would like to
present Kane County Judicial Center with Air Cooled Screw Chilled water
alternative. Petrow explained the benefits of switching to an Air Cooled Chiller
Plant, such as lower maintenance and installation costs, and zero water usage.
He explained the Screw Compressor Technology. He addressed the installation
process of the new Chiller system. He noted that the existing system would need
to have underground piping repaired before being used in the future. This is one
of the main reasons for a proposed Air Cooled Chiller in the future. Petrow
provided a diagram depicting the Primary/Secondary Piping Configuration. He
listed the numerous existing issues with the current chiller plant, such as chiller
leaks, internal rust, and impeller wear. He explained the current compressors'
internal components and that in the Midwest, most chillers do not run at full
force. He spoke on the energy consumption of existing chillers versus an
air-cooled chiller. He mentioned the service lifetime difference of 10K hours for
the existing chiller, and 30K for the air-cooled. F.E. Moran representatives
addressed questions and comments from the Committee. Much discussion
ensued.
Fahnestock provided a summary of the research done by Building Management,
F.E. Moran, and others regarding chillers. He noted that it would not be a good
investment to fix the existing chiller and that it would be more feasible to
purchase replacements. He spoke on the control system and potential
upgrading for the chilling system. He discussed industry supply chain issues and
a chiller replacement cost that is not to exceed $2M in total for the JJC campus.
He expressed concerns about the ordering time frame and receiving the chiller
replacements by Spring 2024. Further discussion ensued.
