Press Release Summary:
Macrowave applies radio waves at 40.68 MHz to remove water from fiberglass batting, board and vermiculite, and prevents migration of aqueous binders. It works on webs up to 12 ft wide. Because water is more responsive to RF energy than most materials, moist areas absorb more RF power than dry areas, which results in uniform drying. Method promotes consistent drying regardless of non-uniform density and moisture content of insulation materials.
Original Press Release:
RF Drying System Improves Insulation Production
A preheating and post oven drying and curing system for the production of insulation batting, board, and vermiculite that provides uniform drying by preferentially heating the moist areas of webs up to 12 ft. wide is being introduced by Radio Frequency Co., Inc. of Millis, Massachusetts.
The Macrowave RF Drying System applies radio waves at 40.68 MHz which uniformly and rapidly removes the water from fiberglass batting, board, and vermiculite and prevents the migration of aqueous binders. Eliminating the wet spots caused by conventional drying methods, the preferential heating and drying involved with RF promotes consistent drying regardless of the non-uniform density and moisture content of insulation materials.
Available for process lines up to 12 ft. wide, the Macrowave RF Drying System replaces the need for long tunnels, long dwell times, and the extra binder materials required to compensate for migration caused by the capillary action of surface drying. Because water is more responsive to RF energy than most dielectric materials, the moist areas of insulation absorb more RF power than the dry areas, which results in uniform drying.
The Macrowave RE Drying Systems are priced from $ 300,000. up, depending upon configuration. Literature and price quotations are available upon request.
