Advantages and possibilities

advantages

Compared to other heating techniques, high frequency has a number of advantages, for example:

  • The processing time is significantly reduced

  • Energy-saving and environmentally friendly

  • No warm-up and cooling time

  • Uniform warming, high product quality

  • No overheating (and therefore less warping and cracking of the wood)

  • Space-saving and lower working costs - and thus a more economical solution

    • HF_setting time

    As shown above, the setting time of a 18m structural beam is just 20 minutes at 650 C when using high frequency, while it is 2-4 hours for cold and hot air – and additional three days resting time at room temperature (200 C). The reduction of the processing time is therefore major when using high frequency.

    Possibilities

    High frequency can be used for the processing of all organic substances, among other things:

  • Gluing wood, plywood, chipboard and fibre material, paper, etc.

  • Drying of wood, chips, paper, cardboard, fleece fabrics, paint, latex foam, gypsum boards

  • Drying of textile coils and trains, chemical and pharmaceutical granulates

  • Drying of water-based adhesives and coatings

  • Pasteurising, baking (combined with infrared)

  • Sterilization of food, beverages and animal feed

  • Defrosting of meat and fish

  • Warming to improve the physical properties (preheating, sintering, melting)

  • Welding of thermoplastics
