Tank Topper Helps Reduce Fuel Evaporation

Tank Topper Helps Reduce Fuel Evaporation ENERGY Fuel-Saving Devices 8-5-4 Fuel evaporation in a 300 gal. tank can cost you 120 gal. a year, say the designers of a new "Tank Topper" protective cover designed to help prevent the costly loss. Minnesotans Jim Kluver, of Raymond, and Earl Klinghagen, of Maynard, teamed up to develop the metal, sun-stopping "Topper". One size fits all tanks up to 1,000 gal. or up to 64 in. in dia. The white corrugated metal sheets (4 by 7¢ ft.) are pre-formed to create the shelter's barn-roof shape. Steel bands and braces supporting the roof bolt into place. Designers Kluver and Klinghagen note that evaporation rates can be as high as 10 gal. per month, or 120 gal. per year in a red, unshielded 300 gal. gas or diesel fuel storage tank. "That's a sizeable 40% loss every year," notes Klinghagen, who figures the Topper can reduce the evaporation loss "by at least 75%, saving you 90 gals. of fuel in just one year. The Topper also helps reduce moisture condensation inside the tank." Sells for $195. For more information, contact: Tebben Mfg., Clara City, Minn. 56222 (ph 612 847-2200).
