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 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.
