Cargill acquires Envirotemp FR3 dielectric fluid business from Cooper Industries

Envirotemp FR3 soy-based, renewable electrical insulation fluid is widely used to improve performance and renewable content of transformers and other electrical apparatus.

Minneapolis and Waukesha, Wis.—Cargill and Cooper Power Systems, Inc., announced Cargill has purchased the global Envirotemp FR3 fluid business and brand from Milwaukee-based Cooper Power Systems, a subsidiary of Cooper Industries plc (NYSE: CBE). Cargill currently manufactures the patented, industry leading FR3 renewable dielectric fluid made from vegetable oil that is used in a wide range of applications for transformers and other electrical equipment, benefitting performance, safety, and the environment.

Having pioneered the natural ester transformer oil market, Cooper Power Systems has significant practical experience with the performance and sustainability advantages of FR3, said Mark Thurman, president, Cooper Power Systems. We expect this market to continue to experience extremely strong growth. We intend to remain at the forefront of innovative engineering design that utilizes these advantages moving forward.

We have a proven track record of manufacturing FR3 fluid as a supplier to Cooper Power Systems, said Kurtis Miller, president, Cargill Industrial Oils & Lubricants (IOL). Now, as a marketer and manufacturer, we will focus on growing the business with other customers seeking a high-performance, renewable fluid. With expertise in the chemistry and applications of renewable oils, and as an independent supplier with world class supply chain capabilities, we will work closely with electrical utility and transformer customers to increase usage of natural, ester-based FR3 fluid.

Cooper Power Systems remains committed to manufacturing innovative power systems solutions that strengthen the grid and have a favorable environmental impact, Thurman said, We are pleased to complete this transaction with Cargill. It is a natural progression for the FR3 fluid business that will allow each company to leverage their core strengths to better serve our valued utility customers and the industry.

A revolutionary product released to market in 1998, Envirotemp FR3 fluid quickly gained global acceptance and has been recognized by the National Electrical Code (NEC), FM Global, Underwriters Laboratories (UL), and the International Electrotechnical Commission (IEC). In 2008, FR3 fluid was approved and listed for the USDA BioPreferred program, and in 2011 FERC approved FR3 fluid for Capital Treatment, which allows utilities to capitalize all costs incurred to retrofill a transformer with the bio-based dielectric coolant. As a result, demand for FR3 fluid has increased, and there are currently more than 450,000 transformers filled with FR3 fluid on six continents.
