Construction of the first metro system in the Middle East required innovative cooling and power solutions. Both cooling and power was required to operate the tunnel boring machine (TBM) and to maintain ambient temperatures in the tunnel for the construction workers, to ensure peak performance.
Aggreko's specially designed chillers supplied cold water to cool the TBM. The TBM machine is used to excavate the tunnels through a variety of different geologies. When in operation the TBM gets extremely hot and if not cooled the drill head begins to erode.
"Aggreko's ability to provide a comprehensive solution, including the supply of cold water and cold air from one cooling system is helping to increase productivity and maintain humane working conditions underground. This is critical as it helps us to maintain the momentum during construction", said Junichiro Nakayama, Project Manager - Bored Tunnel, Japan Turkey Metro Joint Venture.
