When an internationally known brewer that wishes to remain unnamed bought 24 carbon steel tanks for reuse, it first needed to modify the tanks. That included blasting and lining them with a protective coating system. Feature 48 JULY 2018 COATINGSPROMAG.COM T BY JACK INNIS, CONTRIBUTING EDITOR PHOTOS COURTESY ENERFAB Brewery Tank Recoat a Frosty One T he phrase " frosty one" holds special meaning for the hard-working crew of Enerfab Protective Coatings & Linings (PC&L). Enerfab has been lining beer tanks in the Cincinnati, Ohio, area and beyond since 1901, and the PC&L division knows well that working in frosty cellars — 38 °F (3.3 °C) on average — in active breweries is demanding business. It's tough on planners, abrasive blasters, coatings applicators, and everyone involved. And abrasive blasting and relining one brewery's 24 carbon steel tanks, each approximately 31,000 gallons (117, 347.8 L), would be no different. A lthough the owners requested the facility remain anonymous, Enerfab PC&L's Operation Manager Nathan Hartgraves was already familiar with the size and dimensions of the brewery's very large tanks. "e current owner actually bought them from an old brewery about 15 years ago," said Hartgraves. "We do quite a bit of fabrication at our Spring Grove Avenue shop, so when we modified those tanks to fit their new location, we spray installed a lining system." e liner, Munkadur Latiglas, came from Munk + Schmitz, a specialty coatings manufacturer located in Cologne, Germany. But after 15 years, the 25- to 30-mil (635.0‒762.0 microns) Latiglas had developed areas of delamination. e scope of this 40,000-square-foot (3,716.1 m²) project was to remove the Latiglas and spray apply approximately 20 mils (508.0 microns) of Munkadur GL specified for the job. Hey! Enerfab began coating beer barrels 116 years ago with brewer's pitch harvested from trees in the Spring Grove Avenue neighborhood. Munk + Schmitz formulated their first beer barrel coating in 1963. If you ever come across a bottle of dud suds, don't blame these guys! A Way Around This Bottleneck Access to the jobsite, located in an old four-story building, couldn't have been better. Enerfab PC&L simply plunked down their equipment in a gated, vacant lot next door. e lot, which they called a laydown yard, held major pieces of equipment, STEEL EPOXY TANK
