Unique Projects for Unique Clients
NASA has determined that to meet the ongoing demand for deep space communication services, it needs a number of new deep space station antennas at its three Deep Space Network sites. The first of these has been constructed at the Canberra Deep Space Communication Complex.
A truly unique project set in the heart of the Tidbinbilla National Park, Benmax was engaged directly by CSIRO, on behalf of NASA and the Commonwealth, to provide the mechanical HVAC for the new Deep Space Antenna 35 project. Designed by GHD Consultants it is a benchmark installation currently being duplicated throughout the world as the new standard for antennas being constructed across the globe. A combination of domestic comfort cooling and process cooling systems makes the installation a mix of simplicity and complexity. The antenna pedestal office areas are served via a simple central air handler plant and reticulated air systems. The transmitter areas, combined with a complex controls system, serve the central external plant. The central plant deals with both heat rejection from the antenna transmitter equipment, and chilled water cooling systems to the transmitter heat exchangers. Heat rejection pipelines are used to remove waste heat from the transmitter via in slab pipework cast into the outer slab of the antenna with additional cooling via a heat exchanger.
