It is an efficient environmental improvement system that dehumidifies and cools the high-temperature and high-humidity environment at the tunnel face locally.
Dehumidified cold air is ventilated locally through small-diameter ducts. It is particularly effective in large-section shields and ECL/TBM construction. With a rich variety of options, systems can be constructed to suit the installation and ventilation conditions in narrow tunnels, utilizing cold heat sources such as muddy water, spring water, and stream water, as well as oil coolers and fin coil types. We can design according to your requirements, so please feel free to consult with us.
