The FreezPak cold storage facility includes a 190,000 Sqft Freezer with blast freezing capabilities, a 38,000 Sqft Cold Dock, and Facility Operations Offices.
ColonialWebb designed and installed the Ammonia Refrigeration System for the facility. The Engine Room includes two suction pressures, -15°F and +23°F. Each has a variable frequency drive (VFD) to optimize energy. Economizering was also used to precool the ammonia and to assist with the Cold Dock load.
Per the customer’s request, the freezer was provided with 12 each hanging evaporators to provide -5°F room temperature. Three roof-mounted Penthouse evaporators were also provided to maintain +38°F in the Cold Dock. Humidity control was also added on the dock.
ColonialWebb was responsible for the underfloor heating system under the freezer, the ammonia room ventilation and ammonia detection equipment, and a complete PLC control system.
