HP POD 20c capacities

HP POD 20c capacity limitations

The capacity limitations for the HP POD 20c are separated into two categories: electrical power and mechanical cooling capacities. Both of these categories are interdependent and must be considered in conjunction with the overall customer requirements.

Electrical power capacities (critical IT power)

The electrical system of the HP POD 20c contains two main feeds, A and B, that are each rated at 400 A 480 V Delta 3-wire. The HP POD 20c has two critical IT load circuits that are each rated at 200 A, which electrically limits the POD regardless of the redundancy configuration.

Mechanical cooling capacities

The HP POD 20c cooling system consists of 3 zones. Each zone includes 2 heat exchangers and 12 fans. Cooling capacities are based on:

•Chilled water inlet temperature of 15.6ºC (60ºF)

•Pure water cooling

•Chilled water flow rate of 454 lpm (120 gpm)

•Average air flow of 1200 cfm per rack

Overall system capacities

The HP POD 20c overall system capacities are provided in the following table. The customer must understand the level of redundancy that is required for the application and its associated limiting factor.
