Overview 6

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.

HP POD 20c capacities

Site requirements
Site pad
The structural design of the HP POD 20c site pad must be based on the specific weight load of the complete
POD solution with IT installed, as well as any additional equipment. During design calculations, HP
recommends that you provide structural support along the entire perimeter of the POD and use the maximum
allowable POD weight.
Upon installation, the POD structure must be leveled to less than or equal to 0.5º. Shimming is allowed
around the perimeter of the POD to ensure that the POD remains level. If significant shimming is required,
shims should be spaced no less than 1.2 m (4 ft) apart to ensure sufficient load transfer. Shims are not
included.
IMPORTANT: The HP POD 20c is designed for ground level installation. If you install the HP POD
20c on an elevated surface, verify that the minimum height requirements for circuit breaker
actuators are considered per national, regional, and local regulations and electrical codes. The
area in front of the outside panels must include a work platform.

HP POD 20c weight
IMPORTANT: The weight provided is a minimum and an absolute maximum rated weight. The
total weight of the HP POD 20c differs based on the IT equipment and optional components
purchased and installed.
The overall weight might significantly vary depending on the final customer-chosen solution for the HP POD
20c. Each site pad must meet the weight requirements of the equipment that is expected to be installed.
The HP POD 20c must be installed on a surface capable of supporting the following weights:

•

HP POD 20c with no IT equipment installed—Approximately 7,711 kg (17,000 lb)

•

HP POD 20c with IT equipment installed—Maximum 22,680 kg (50,000 lb)

Dimensions and clearances
The selected site for the HP POD 20c must be large enough to install, service, maintain, and provide space
for potential growth or expansion with additional PODs.

The following are the water quality requirements and specifications:

•

Closed-loop water must not contain any lime scale deposits or loose debris.

•

The temperature of the chilled water supplied to the HP POD 20c must be 12ºC to 24ºC (55ºF to 75ºF).
CAUTION: Freezing water can cause a blockage and damage to the unit. In outside locations
that are subject to freezing temperatures, an additive such as glycol might be necessary to lower
the freezing point. However, since the heat transfer potential of water with glycol is lower, the HP
POD 20c must be de-rated accordingly.
IMPORTANT: The chilled water system piping and heat exchangers must be drained completely,
and then purged using compressed air when storing or transporting at or below freezing
temperatures.
IMPORTANT: Operating the chilled water system at the higher end of the acceptable range
decreases the overall thermal capacity of the POD.

Site requirements

These actions must be performed for all associated parts of the electrical power train. The majority of the
details and factors required to complete these studies are associated with the existing installed facility
infrastructure.
CAUTION: Failure to complete these studies can cause serious issues with the electrical
integration of the POD into your electrical system.

Electrical power system configuration
A preliminary meeting with the HP POD Electrical Engineering team is necessary to discuss your decision
concerning capacity limitations and the impacts of this decision on the electrical design.
A 1N electrical configuration can be achieved by providing all of the required electrical feeders from a
common power source, common switchboards, and transformers.
A 2N electrical configuration can be achieved by feeding parallel power paths from independent power
sources, switchboards, and transformers.

Site requirements

Supported facility connections
Environmental control system
The ECS developed for the HP water-cooled POD is a stand-alone control system that requires no external
connections with an external site system, BMS, public or private Internet sites, cloud, or wireless system to
