A. Provide ten (10), 480V, electric, factory assembled, centrifugal chillers complete with compressor, motor, unit mounted variable speed drive (VSD)/adjustable frequency drive (AFD), evaporator, condenser, microprocessor controls, graphics and all required ancillary equipment including permanent refrigerant pump out unit. The chillers shall be configured in a seriescounterflow arrangement with integrated controls and will be field installed to operate in a headered, variable primary chilled water pumping system. The chillers will also be connected to a headered condenser water system with five (5) field erected cooling towers. B. Each series-counterflow chiller pair shall have a guaranteed capacity of 2,500 tons at the design conditions that are listed in the table in Part 5 of this section. C. The maximum chiller dimensions for each individual chiller in the series-counterflow pair cannot exceed the following: 1. Overall unit length: 24’-6”. 2. Chiller width including unit mounted VSD: 11'-9". 3. Chiller height: 14’-0”. D. The opening to rig the chillers into the Bernard Chiller Plant (BCP) is through a vertical bifold door on the north side of the plant. The clear opening of this door is approximately 20’-0” wide and 18’-0” tall.
