Waukesha Electric Systems, Waukesha, Wis., and Cooper Power Systems recently announced an exclusive agreement in which the nationwide WES Service organization will provide field retrofill services using Cooper Power Systems’ new Envirotemp FR3 coolant for transformers and substation equipment.

“FR3 can provide significant cost savings and technical benefits when compared with the petroleum-based coolants traditionally used in substation equipment,” says Nancy M. Dickman, president of Waukesha Electric Systems. “Additional benefits include improved fire and environmental safety as well as extending the performance life of transformers.”
