generated purely from the waste heat of its industrial welding processes. Previ- ously, in its older plant, the company used supplemental heaters, kept the ship- ping doors open more frequently, and used exhaust fans to expel welding fumes—and wintertime heat. Now the company incurs no supplemental winter heating costs, significantly reduces heat
loss during open-door periods, and recir- culates heated air through the air curtains. The air curtains activate manually or with a limit switch triggered by a door opening. They draw interior air from the facility and discharge it through
field-adjustable nozzles.

Air Curtains Slash
Energy Costs, Filter
Welding Fumes
Coleman Tool & Mfg. Co., Union Grove, WI, a metal fabricator of replacement parts for garbage trucks, roll-off trucks, refuse equipment and similar applica- tions, originally specified air curtains above its open doorways to reduce its monthly winter heating costs. It soon dis- covered an added benefit of the air cur- tains (from Berner Intl., New Castle, PA): filtering welding fumes, to significantly improve employee indoor air quality (IAQ).
For its new 60,000-sq.-ft. plant, Coleman specified air curtains, above two 16 by 16-ft. and one 12 by 12-ft. overhead doors. The curtains retain heat while the doors are open, allowing the irm to maintain a 60 F wintertime temperature
