Underground tunnel case study
Aggreko ensures the best possible finish for a tunnel
The challenge for the customer
Tunnelling conditions in a time
sensitive motorway project were causing difficulty. Humidity
and cold temperatures 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: oil fired heater rental
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.
