The newest T100G tunnel with custom coverage. In this case, the double air-pump system consists of two different layers - Deltaclim 180 mic externally and Deltatex 150 mic internally with anti-condensation AF coating. The entire facility is a classic structure on pipes, 10 m wide and 34 m long. The owner decided to equip the tunnel with 3 sliding doors and air vents on the front walls.
