The Challenge for the Customer
Electric motors driving fans at an Arizona mine were performing poorly. An error had resulted in too low a specification and consequent overheating. An ambient temperature, sometimes exceeding 100 degrees Fahrenheit, was compounding the problem. To replace the motors was very expensive, and productivity at the mine needed to be maintained.
Aggreko applied a combination of experience and ingenuity to deliver a solution. Industrial air-conditioners provided a constant source of chilled air that was directed across the motor coils. This additional cooling allowed the motors to perform better and the air blowers to operate as intended.
The Benefits to the Customer
Thanks to Aggreko’s lateral thinking and range of available plant the mine was able to continue to operate uninterrupted. Production and output was increased and the capital cost of replacing the electric motors was avoided.
