Save space and energy with this radio frequency dryer
The Macrowave RF Drying System provides greater efficiency that conventional convection and infrared systems for the high-speed drying of water-based patterned glue and coatings in the converting and textile industries. This 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, says the manufacturer. Capable of operating at speeds up to 2,000 ft/min, 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 says the company. — Radio Frequency Co., Inc., Millis, Mass.
