During the winter months, average daytime highs in Rochester, Minn., hover in the mid-20s (F). Such prolonged cold took a toll on the town’s above-ground potable water storage tanks. Ice buildup sometimes measured as much as two feet thick inside the larger tanks, chipping away at paint on the interior walls and causing extra maintenance and expense.
Searching for a better alternative than simply exercising the tanks, Rochester Public Utilities officials learned that GridBee® GS-12 submersible electric mixers from Medora Corporation, Dickinson, N. D., might provide the solution.
Based on the same long-distance mixing technology as SolarBee® solar-powered units, GridBee® electric tank mixers provide municipalities with a low-cost solution for preventing ice damage and meeting water quality standards.
