Tunnel of Perthus | Case Study | Aggreko plc

Heaters and Air Movers Keep an Underground Tunnel Project on Schedule

The Challenge to the Customer

A contractor building tunnels on a new motorway was having problems with a combination of low temperatures and condensation during the process of painting the tunnel.

Aggreko's Solution

Due to tight timescales, a quick solution was imperative. Aggreko supplied 4 x 125 kW oil-fired heaters, which blew out hot, dry air, which was circulated inside the tunnel by 8 x 5,000 cfm air movers, all being powered by an Aggreko generator.

Benefits to the Customer

A comfortable working environment for personnel to perform their daily tasks, as well as reducing impact on the overall construction programme.
