Thermex-Thermatron is the high-frequency heating specialist manufacturer of industrial microwave generators, industrial microwave ovens, industrial microwave dryers, and pultrusion preheaters, as well as complete lines of other RF heating equipment and systems. The advantages of this unique high frequency heating technology are numerous, and the technology is used on thousands of different products every day. Microwave and RF technology provides the most direct and efficient means of heating select materials or assemblies. Its versatility and speed have provided for increased productivity, lower operating costs, higher yield, reduced emissions (pollution), and in many cases, better quality products for new and existing applications.
Industrial RF Oven / Batch Drying System
The shielded chambers where material to be heated is placed between the electrodes or plates are called the Radio Frequency Ovens (RF Ovens), or Batch Drying Systems. Inside these chambers the electrodes and the material form the output capacitor of the RF generator, where the material converts high frequency energy supplied by the generator into direct heating of the entire material. These industrial RF ovens are used in products with high loss factors such as vinyl, plastics and other non-electrically conductive products, providing faster and uniform drying.
Thermex-Thermatron’s RF Drying Systems incorporate all of the inherent design subtleties and complexities of our conventional RF ovens along with several unique to themselves. Our RF Dryers use efficient hot air convection which enhances the drying process while protecting product surfaces. The RF Drying Systems are accompanied by a completely self-contained Thermex RF Generator.

Industrial RF Conveyorized Drying System
The RF Conveyorized Drying System is meeting market demand for a new generation of RF drying systems that can produce sustained power output levels of up to 120kW to a suitable dielectric load in a stable high voltage, high frequency environment. It is now possible to take a specific dielectric drying need and introduce the environment necessary to provide the desired heat and heating rate all under the watchful eye of a PLC programmed for real time response. The synergy of hot air convection is provided with the inclusion of continuously adjustable humidified air in order to manage the moisture released during the process. At the same time the efficiency of the drying process is enhanced while protecting product surfaces.
The system is also provided with the necessary features to continuously transport the product during the heating process, separate and remove unwanted moisture and report quality oriented results over selected time periods. This is accomplished while providing for the uniform introduction of heat or product profiling, whichever the product and process require. Both the applicator and generator are provided with large, hinged access doors incorporating redundant interlocks to address ease of access for the purpose of installation, process inspection, and maintenance or cleaning. Redundancy provides an additional layer of operator protection should the doors be accidentally opened during operation.

Industrial RF Generators
Industrial RF Generators convert low-voltage power-line frequency to high frequency and voltage suitable for heating materials with resident dipoles.
The objective of a well-designed and manufactured RF Generator is to efficiently produce high frequency power while being flexible enough to interface with a variety of electrode systems and customer products. The objective is not simply the stabilization of frequency at some artificially established level but rather the provision and management of what is best for the process.
Thermex Industrial RF Generators range from the largest single Radio Frequency system ever conceived and built, to frequency-stabilized arrays of modular equipment. They have been interfaced to a wide range of applicators from the largest single opening press ever developed in the wood industry to continuous-duty convection/dielectric oven dryers to conventional and staggered fringe-field Web Dryers. The generator is the heart and soul of any RF System, and Thermex generators have proven themselves over time and numerous application challenges.
