Ann Arbor Federal Building – Ann Arbor, MI
In early July of 2017, Advantage Mechanical-Refrigeration (AMR) concluded a vast service project at the Ann Arbor Federal Building in Ann Arbor, Michigan. AMR was responsible for installing a 20-ton dry cooling unit on the roof and a glycol pumping station . This project’s purpose was to provide better air conditioning quality to the building as well as reduce energy costs. This project was designed to better improve the facility by allowing the building to run more efficiently and in turn save money.
This 2-part project began in May and AMR hit the ground running as the completion date was only 2 months away. Thanks to AMR’s crane subcontractor, JJ Curran Crane Company, the 20-ton unit was successfully lifted onto the roof and into place to begin installation. Next, AMR measured, cut, and installed 380 feet of 3-inch, 280 feet of 2½-inch, and 250 feet of 2-inch copper. The copper was then hung in the ceiling of the existing building and connected with copper fittings to three existing heat pumps.
Lastly, AMR installed a glycol pumping station for the 20-ton unit. A glycol pumping station is designed to move glycol through the system. For this project specifically, the station is estimated to reduce water consumption by over 2 million gallons each year! In large thanks to AMR’s service technicians, who spent several long days, nights, and extra time away from their families, this job was completed on time and under budget. AMR is proud of it’s reputation amongst its U.S. government cliental in the state of Michigan and looks forward to completing more projects like this in the future!
