Overview: Established in 1987 as a joint venture between Nisshinbo Industries, Inc., one of Japan's largest textile manufacturers, and Kanematsu Corporation, a large Japanese trading company, NCI's Fresno facility is the only spinning and weaving plant in the Western half of the United States. NCI's ventilation system uses nine supply fans (SFs) and nine return fans (RFs) to circulate high humidity air to maintain proper ambient conditions, cool process machinery, and control suspended particulate and airborne fibers. Installation of the VFDs reduced the ventilation system's total electricity demand from approximately 322 kW to 133 kW, a 59 percent drop. The total annual energy consumption for the fans similarly fell 59 percent from approximately 2,700,000 kWh to 1,100,000 kWh.
