EPC Contractor’s Role:
Pump pipe cross-connectivity reliability concerns were addressed
by the installation of motorized isolation valves in the chilled water
and condensed water piping. Additional piping cross connects
and manual bypass/isolation valves were also included to allow
dedicated chilled and condensed water pumps to cross connect
to other nearby chillers. Variable frequency drives were added
to the cooling tower fans, chilled water pumps, and condensed
water pumps to provide greater control of the chilled water and
condenser water pumping systems. By adding additional cooling
tower capacity and manual valves/bypass connections, a higher
level of redundancy was achieved.
