Underground tunnel case study
Aggreko ensures the best possible finish for a tunnel
The challenge for the customer
Tunnelling conditions in this time sensitive motorway project
were causing difficulty. Humidity and cold temperature within
the tunnel were delaying the painting of the tunnel surfaces.
An essential requirement was to raise temperature and dry out the
tunnel environment.
Aggreko’s solution
To keep the project on track, Aggreko supplied four 125Kw oil
fired heaters, which deliver hot, dry air. Eight 5,000 cfm
air movers ensured this dry air reached all parts of the
tunnel. An Aggreko diesel generator provided the electrical
power required.
The benefits to the customer
Dampness within the tunnel was rapidly reduced, and ambient
temperature raised. The painting was able to proceed to
schedule, bringing the project to a successful conclusion
