Macrowave™ Drying Systems Improve Quality and
Productivity in the Production of Synthetic Foams

Radio Frequency Company of Millis Massachusetts raises the bar again with its latest generation of Macrowave™ Foam Drying Systems which gently heat and uniformly dry synthetic foams evenly throughout their entire thickness in a fraction of conventional drying times. Macrowave™ Systems apply radio waves to foam webs or buns up to four feet thick at a frequency of 40.68 MHz which rapidly removes water without the quality control problems associated with conventional drying systems such as, surface discoloration, cupping caused by nonuniform shrinkage, and surface hardening.

Macrowave™ Systems are also capable of drying water-based glues used in the construction of foam laminations up to several feet thick. Because Macrowave™ energy will preferentially heat materials where the water content is the highest, the wet glues are heated and dried without directly heating the cured foams, avoiding quality problems associated with overheating.

Radio Frequency Company offers its Process Development Laboratory services in Millis, MA to assist clients in developing the most efficient means to accomplish their foam processing objectives. Featuring the Macrowave™ OmniTherm™ Simulator which can apply RF and conventional heat to simulate actual production conditions and provide a computerized record of all process parameters enabling accurate scale-up requirements. Lease systems are also available for conducting in-plant trials.
