VERTICAL NON-CONTACT WEB DRYER Custom engineered RF (radio frequency) vertical non-contact web dryers for manufacturers of water-based coated substrates that rapidly remove moisture from the web at low temperatures and reduce product make-ready times are available from Radio Frequency Co., Inc. of Millis, Massachusetts. 
The Macrowave™ Vertical Noncontact RF Web Dryer rapidly removes moisture from the web at 170ºF and prevents the migration of coating solids caused by conventional drying which increases web strength and product quality. Featuring preferential heating to selectively dry the wettest sections of the web, this dryer eliminates the need for accumulation rollers required by festooned convection and infrared type dryers and saves floor space. Providing instant ON/OFF control, the Macrowave™ Vertical Noncontact RF Web Dryer eliminates the heat-up and cool-down times required by conven tional dryers, minimizes the quantity of product in the drying cycle and reduces changeover time. According to the firm, a vertical noncontact RF web dryer generally requires one-fifth of the floor space needed for hot air and IR dryers and lowers maintenance costs. The Macrowave™ Vertical Noncontact RF Web Dryer is priced from $100,000 up, depending upon configuration. Literature is available upon request.
