A concept that can be used in the manufacturing industry the world over, RF heating and drying can assist in reducing emissions, improving efficiency and speeding up the production process.

Industrial based RF heating and drying is fast and flexible. It allows for a quicker and streamlined production process for many manufacturing applications. This provides uniform heating and drying, a reduction in emissions and improvements in product quality and efficiency.

This concept can be used for a wide range of different professions. RF heating and drying can be used for medical purposes e.g. for blood and organ warming, for white good appliances and for scientific purposes such as chemical processing.

RF acts as a volumetric heat source effectively depositing energy inside large loads and preventing large temperature gradients.

Materials with poor heat transfer characteristics such as ceramics and glass fibres, have traditionally been problem materials when it comes to heating and drying.

Conventional heating of material wastes energy during heating due to inefficiency of conduction and connection-based heating mechanisms.

Warping, surface discoloration and cracking associated with conventional drying methods can all be avoided with RF solutions.

Longevity semiconductor technology can easily be much larger than tube-based technology.
