Radio frequency drying system provides efficient, selective heat

Graphics | September 1, 2009 | By:

Radio Frequency Co. Inc. introduced a radio frequency drying system that provides greater efficiency than conventional web dryers and enables the high-speed drying of water-based patterned glue and coatings at line speeds previously reached only with solvent based coatings.

The Macrowave RF Drying System selectively heats only the coated portions on the web, leaving the bound moisture in the substrate intact, preventing over-drying, distortion, and shrinking. Capable of operating at speeds up to 1500 FPM, the system needs one-fifth to one-third of the floor space required for hot air and IR dryers, permits lower web temperatures, and provides up to 50 percent energy savings, according to the company.

The Macrowave RF Drying System can be configured to handle webs up to 120-inches wide and meets OSHA safety regulations and FCC standards on communication non-interference.
