Airing Out the Options

One combination is high-velocity, hot-air impingement with infrared heaters between the air nozzles. “The typical solution to problems with drying waterborne coatings is to slow down the line, giving the product more dwell time in the dryer, or use longer ovens,” says Jim Alimena, Glenro’s vice president of marketing. “Unfortunately, any gains in product quality achieved in these ways may be offset by losses in productivity and plant floor space. Glenro’s hot air/infrared systems allow you to run coating lines at maximum speed without sacrificing product quality, and without wasting precious floor space.”
