The first ever SolarDuct installation in Illinois is nearing completion at the new Joliet Junior College Facilities Services Building.  HarneTech provided the SolarDuct material and assisted with the design of the system.  Installation is being completed by Mechanical Inc.

The SolarDuct system is a rooftop solar air heating system that pre-heats ventilation air for the building.  The significant temperature rise achieved by the SolarDucts reduces the requirement of traditional heating fuels for the building, providing a rapid return on investment.
