Fabric duct helps save high school $380,000, no sweat
KSA's John Kluber, P.E., vice president, and Donald Ware, P.E., chief engineer, searched for a solution to ductwork sweating because of the significant savings at stake. Averaged at $3/cfm, Kluber's low temperature supply strategy reduced air volume by 100,000 cfm and saved $300,000 in equipment costs, not to mention the additional future operating costs of downsized equipment.
Instead of increasing the expense of additional ductwork insulation to prevent sweating, fabric duct was specified since it naturally prevents condensation from developing on the fabric surface. Kluber specified DuctSox fabric ductwork in the 430,000-sq-ft high school's 20,000-sq-ft cafeteria, the 38,000-sq-ft field house, the 13,000-sq-ft natatorium, and 3,800 sq ft of open architecture administrative offices.
