FANQUIP has designed and fitted a system that pumps ambient and fresh air to aid maintenance workers in a 200m long tunnel.
The installation, at a large aluminium smelter in NSW, was designed to eliminate stale air by creating air movement throughout the tunnel. The client required the system because it needed to perform scheduled maintenance work under some large tanks in the tunnel.
The air movement supplier had to synchronise its work with the schedule for the maintenance works. It also had to ensure the project was expedient and accurate so it will not get in the way of maintenance crews.
The maintenance program was expected to run for 18 months, so the air movement solution was built to last for that period of time.
One of the main technologies installed were high flow and high pressure axial fans in different sizes and capacities, as well as ducting.
The company used ruggedised direct drive and short case axial flow fans made in Australia. It claims the fans are designed to withstand harsh operating conditions across all industries.
The direct drive axial flow fans are hot tip galvanised to lengthen their lifespan in exposed conditions or remote locations. They are equipped with heavy industrial rolled casing to provide added protection against physical stresses and temperature changes. Fanquip also installed an external junction box for quick accessibility.
The short case axial flow fans are also hot tip galvanised, but have a short casing length for operation in restricted spaces. They have IP55 rated motors, with sizes ranging from 305mm to 610mm in diameter.
According to the company, a range of motor options can be used with the fans. These include dust-proofed and hose-proofed safe motors, flame-proof motors, and two-stage motors.
