Heat Exchanger Performs 3 Functions
August 1, 2006
LC Series will simultaneously cool compressed air, heat vaporized nitrogen gas and cool compressor oil. The three-in-one design simplifies upfront engineering, requires less floor space and eases installation, maintenance and operation. Model pictured drafts 15,000 cfm of 90°F (32°C) ambient cooling air, pulled vertically through a three-circuit, fintube core by a 48" dia., 3 hp electric fan. The largest circuit cools a 2,000 scfm flow of air at 100 psig from 210°F (99°C) to 120°F (49°C). A second circuit cools a 9 gal/min flow of compressor oil from 160°F (71°C) to 130°F (54°C). The third circuit superheats 200 scfm of nitrogen gas from an evaporator at 120 psig from -200°F (-129°C) to 40°F (4°C).
