The previous chiller plant for this 236,665 SF commercial property utilized a 750 Trane absorption Chiller. However, not having redundancy on the systems, and its low load operation flexibility, forced the owner to pursue a flexible, reliable and low energy solution.

DM Engineering was engaged by the property manager to provide a cost-effective and reliable engineering solution. The specified and installed new chiller plant involved two double compressors Daikin Magnitude magnetic bearing centrifugal 375-ton chillers which proved to be extremely energy-efficient with excellent part-load performance.

The project also included a rigging path to the basement. DM Engineers worked with the manufacturer and structural engineer to customize the tubes in order to rig the equipment down a passenger elevator.

The electrical engineering scope of work included the demolition of all feeders serving existing chillers, and drives, and replacing them with a new service and transformer to accommodate the new equipment load.
