Atwo-pass, energy-efficient, electric infrared dryer from Paterson, N.J.-based Glenro Inc. lowers
moisture content in paper and other materials prior to calendering. Two webs, each in a
face-to-face position, pass through the dryers 12 infrared heaters simultaneously at speeds of up
to 600 feet per minute. The webs receive heated air via stainless steel tubes. The heated air helps
break the boundary layer of air surrounding each moving web, remove vapors and accelerate the
drying process. Heavily insulated walls help contain process heat, according to Glenro.The dryer
uses a SCR control system that maintains constant product temperatures. Low-noise blowers provide
quite operation.
