IBM Rear Door Heat eXchanger
IBM offers an alternative to standard air cooling systems with the IBM Rear Door Heat eXchanger (part
number 43V6048). The Rear Door Heat eXchanger replaces the existing rear door of an iDataPlex rack
and provides an extremely efficient water-based cooling solution. The exchanger dissipates heat
generated by all servers and provides the data center with cooling at the most efficient place, which is
immediately behind the exhaust of the system fans.
The Rear Door Heat eXchanger has the following specifications:
Dimensions:

Width: 1190 mm (46.9 in.)

Depth: 120 mm (4.7 in.)

Height: 1995 mm (78.5 in.)

The heat exchanger adds 127 mm (5 in.) to iDataPlex Rack depth if the casters are removed.
Doorway dimensions:

Minimum height: 2020 mm (79.5 in.)

Recommended height: 2057 mm (81 in.)

Weight:

77 kg (170 lb) empty

91 kg (200 lb) full, with water

Depending on conditions, the Rear Door Heat eXchanger can extract all heat produced by equipment
using 30 kWh of energy (while operating at 90 - 94% of the door's maximum efficiency). The Rear Door
Heat eXchanger does not use electricity.
