Secured water supply
With an ultimate annual capacity of 160 million passengers, Dubai World Central is set to become the largest airport in the world. Problems in the system supplying fresh water to the complex were causing frequent breakdowns and noisy operation, affecting staff and travellers alike.
Previously, water pumps were limited to on/off control, with constant full speed operation causing regular breakages in expansion tank bladders and pipework, pressure surges, water hammer and frequent pump stop/start. The challenge was to provide a solution that would provide constant and reliable system pressure to match the varying demand.
Working closely with the airport’s engineering department, Grundfos technical specialists carried out a full survey of the system and recommended converting to automatic variable speed control with soft stop/start to match actual demand. They installed and commissioned a new Grundfos Hydro MPC-EC integrated VFD controller with microprocessor control unit to replace the existing booster control panel, and two new 200-litre expansion tanks to replace the previous damaged 3000 and 2000 litre tanks. The new system is not only more efficient and reliable, overcoming all previous system problems, but significantly reduces the time and cost of preventative maintenance on the expansion tanks, and requires much less energy to operate.
Operational problems overcome; Improved system efficiency; savings in energy and maintenance costs.
