AlfaTech provided mechanical and electrical engineering services for the Southern California Edison Alhambra Data Center. The critical cooling systems supporting the data center include ten (10) existing nominal 305kW Indirect Evaporative Cooling (IEC) Air Handling Units (AHU) with an integral indirect evaporative air-to-air heat exchanger, DX trim cooling evaporator and condenser coils, and make-up water distribution piping, pumps, and storage. Each IEC AHU includes a 147kW indirect evaporative air-to-air heat exchanger in series with a 158kW DX trim cooling evaporator coil that combine to provide the full 305kW unit cooling capacity. The existing IEC AHUs are internally N+1 component redundant. The project included developing the scope for a future facility renovation to provide redundant DX air-cooled heat rejection, to replicate the full heat rejection capability of the existing IEC AHUs and the potential addition of supplemental, redundant HVAC units.

AlfaTech worked with RY+AO on this project.
