RF Web Drying System can operate at speeds up to 1,500 fpm.

Press Release Summary:




Designed for high-speed drying of water-based patterned glue and coatings, Macrowave(TM) RF Drying System selectively heats only patterned coatings on web and leaves bound moisture in substrate intact, preventing over-drying, distortion, and shrinking. It needs 1/3 to 1/5 of floor space required for hot air and IR dryers, and permits lower web temperatures. Unit can handle webs up to 120° wide and meets OSHA safety regulations and FCC standards on communication non-interference.



Original Press Release:



New High Speed, Eco-Friendly RF Web Drying System for Patterned Water-Based Glue and Coatings



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(TM) 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 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(TM) 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(TM) RF Drying Systems handle webs up to 120° wide and meet OSHA safety regulations and FCC standards on communication non-interference.

The Macrowave(TM) RF Drying Systems are priced from $60,000 up, depending upon configuration. Feasibility studies, and quotations are available on request.
