Technologies / Dielectric heating

NIS Ltd, supported by our sister company Petrie Technologies Ltd, lead the way in the implementation of industrial dielectric solutions using Radio Frequency or Microwave heating. Previously supplied equipment ranges in power outputs from just a few kW to 450kW for our larger, continuous units.

Key advantages for the use of this technology and specifically related to NIS/Petrie supplied equipment are;

  • Increase in thermal efficiency (rates of heat transfer) often resulting in reduced process times
  • Selective drying or moisture profiling
  • Unique software design ensures precise control of power to each product
  • Maximised final product quality
  • Safe use
  • Continuous systems and batch production units

We have provided solutions for medical product manufacture, composite and ceramic manufacture as well as the food industry in baking bread, potatoes, meat and numerous other products.

From welding to baking to curing, NIS, through the application of Petrie Technology, have the capability to supply or enhance batch or continuous production lines using Radio Frequency or Microwave systems.
