MILLIS, MA | Radio Frequency Co. introduces the Macrowave RF Drying System, which is said to provide greater efficiency than conventional convection and infrared systems for the high-speed drying of water-based patterned glue and coatings.
The system selectively heats only the patterned coatings (wetted sections) on the web and leaves the bound moisture in the substrate intact, thus preventing over-drying, distortion, and shrinking. Capable of operating at speeds up to 1500 FPM, this system needs one-third to one-fifth of the floor space required for hot air and IR dryers, permits lower web temperatures, and provides up to 80% energy savings.
Eliminating the long dwell times associated with conventional heating methods, the Macrowave RF Drying System reduces makeready because RF power is instant ON/OFF and energy is only consumed with a load in the system. Macrowave RF Drying Systems handle webs up to 120 in. wide and meet OSHA safety regulations and FCC standards on communication non-interference.
The systems are priced from $60,000 up, depending upon configuration. Feasibility studies, and quotations are available on request.
