Preferred Utilities recently did a fuel oil project at a building that might be termed mission critical. This building will house the airline communication center (ACC) for one of the largest airlines in the country. The FAA<\/span><\/a><\/span> requires that airlines be in constant communication with all their active planes at all times.<\/p>\n If they lose communication with a plane, that plane can\u2019t fly. If it\u2019s in the air, the plane has to land. If the airline\u2019s ACC loses power, all their planes are immediately grounded. Losing communications with aircraft would require the airline to ground its fleet, resulting in a huge negative impact across the national airspace system.<\/p>\n The building that houses the ACC is on grid power. But it also has three generators, each with it\u2019s own over-sized belly tank. The airline wanted this building to be tornado resistant, so the generators, belly tanks, and fuel supply system is all below grade. We provided Model 3 fill boxes so even the fill lines for the belly tanks are underground.<\/p>\n The generator to the left is one of three that can provide power for the building if the grid power fails. The Preferred PWC-based fuel controller <\/span><\/a><\/span>provides tank gauging, leak detection, and overfill protection for the belly tanks for the three generators.<\/p>\n The image to the bottom right shows tank 1 being filled during final construction of the building. The Preferred system provides tank volume display at the fill port, as well as an overfill alarm at 85% full, and will shut off the fill line at 95% full.<\/p>\n![\"Emergency](\"http:\/\/preferred-mfg.com\/blog\/wp-content\/uploads\/2014\/02\/IMG-20131101-00125-300x225.gif\")
