Aggreko Takes the Heat Off Arizona Mining Company

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°F, was compounding the problem. To replace the motors was very expensive, and productivity at the mine needed to be maintained.

Aggreko’s Solution

Aggreko applied a combination of experience and ingenuity to deliver a solution. Industrial rental 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 Benefit to the Customer

Thanks to Aggreko’s lateral thinking and problem solving capabilities, the mine was able to continue to operate uninterrupted. Production and output were increased and the capital cost of replacing the electric motors was avoided.
