MENOMINEE—Menominee’s own R.W. Fernstrum & Company is receiving statewide recognition for its GRIDCOOLER® Keel Cooler, which has been nominated for the 2021 “Coolest Thing Made in Michigan” presented by the Michigan Manufacturers Association (MMA).

This “Coolest Thing Made in Michigan” is part of MMA’s annual recognition of the exceptional products made across the State of Michigan and a celebration of the contributions manufacturers make to Michigan’s economy and local communities. Thirty-seven Michigan-made products from around the state are included in this year’s competition.

In Voting Round 1, open through Friday, anyone can vote daily for up to four products at These votes determine which products make it into the top ten in voting round 2. The winner of the “Coolest Thing Made in Michigan” will be announced during the 2021 MFG Excellence Awards event in early November.

“Being nominated for ‘Coolest Thing Made in Michigan’ is a great honor and it would mean so much to our entire team to win the title,” said R.W. Fernstrum & Company President Sean Fernstrum. “Of course, it’s hard to compete with Michigan-made products like ice cream and beer so that’s why we’re calling on our friends and neighbors for their support and votes. Winning would truly be a victory for the entire Menominee area community.”

R.W. Fernstrum & Company is a fourth-generation, family owned and operated business that has been based out of Menominee, since its founding in 1949. The company got its start during World War II when the U.S. Navy encountered engine cooling problems with its landing craft and required a new closed circuit cooling system. After intense research, Robert W. Fernstrum developed and patented the first rectangular tube keel cooler design that is still used today.

Fernstrum’s GRIDCOOLER® Keel Cooler has evolved over the years into a line of keel coolers that offers nearly limitless variations to fit a particular application. Each solution is engineered to meet the requirements of the engine, vessel and operating conditions. Active in all sectors of the workboat and brown water sectors, Fernstrum is also active in wind and tidal energy projects. Although Menominee is its home base, Fernstrum does business worldwide with about 30 percent of sales happening outside the U.S. across six continents and over 53 countries. Notably, R.W. Fernstrum & Company received ISO 9001:2015 certification in May 2018.
