The new Macrowave™ radio frequency drying system from Radio Frequency Co., Inc. can offer greater efficiency than conventional web dryers and enable the high-speed drying of water-based patterned glue and coatings at line speeds previously reached only with solvent-based coatings. The system selectively heats only the coated portions on the web, leaving the bound moisture in the substrate intact, thus preventing over-drying, discoloration, distortion and shrinkage. Capable of operating at web speeds up to 1500 FPM, this system requires a smaller footprint than other dryers, allows for lower web temperatures, and provides up to 50% energy savings.
