The conditions in the warehouse are maintained by two Powerpax water cooled chillers located in a remote plant room. These chillers reject heat through two cooling towers located in the same plantroom. Chilled water is pumped from the HVAC plantroom to 16 airhandling units located on the main warehouse roof. These airhandling units supply conditioned air to the warehouse via a distribution of ductwork and air diffusers.
The internal design temperature for the 30,000 m2 warehouse is 22.0c deg
