The workshop building is in an elevated position and the prevailing winds blow directly into the shop. The mine is a world class coal asset located 40 km east of Mudgee in the Upper Hunter Valley, New South Wales, Australia. Production is expected to reach around 12 million metric tons per year.

The mine needed a solution to enhance the working environment with the ability to seal up the openings when the weather turns for the worse. The Megadoor system was able to fulfill the customer requirements as it provides the best sealing properties on the market and keeps air infiltration to a minimum. The system has been proven to offer reliability with minimal maintenance requirements and 100% safe operation, giving its customers peace of mind. The order included four series S1000 and two series S800, with sizes ranging from 6- x 5-m up to 12- x 11-m. All doors were supplied with translucent fabric that maximizes the amount of natural light into the building for a pleasant and energy-efficient working environment.

The order was placed in May 2011 and the installation was completed in September 2011. The system was manufactured in Skellefteå, Sweden.
