A drying system that provides greater efficiency than conventional convection and infrared systems for the high-speed drying of water-based patterned glue and coatings in the converting and textile industries is being introduced by Radio Frequency Co., Inc. of Millis, Massachusetts.
The Macrowave RF Drying 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 2000 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 make-ready 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" wide and meet OSHA safety regulations and FCC standards on communication non-interference.
