PSC, Inc., a subsidiary of Litzler, manufacturers Radio Frequency (RF) ovens and dryers. Radio Frequency or Dielectric Heating utilizes Radio Frequencies between 10-100 MHZ to dry or heat product. RF drying is normally used in products with high loss factors, such as wet materials, vinyl, plastics and adhesives, and other non-electrically conductive products. RF provides significant advantages of faster drying time, less floor space, uniform drying, instant on-off and targeted drying. Depending on the application, PSC uses parallel plate, stray-field or staggered stray-field for the most uniform heating.
To maximize the benefits of both convection and radio frequency, Litzler and PSC work together to design a combination oven. Four main combinations include RF pre-heat, RF boost, RF finish, and full RF/Convection. Each combination offers benefits to significantly improve the drying process.
