About our industrial microwave technology

Our industrial microwave technology has been developed to help production-based industries meet the challenges of a global economy and lower emissions targets.

Unlike conventional gas drying, our displacement technology is proven to heat the entire material by drying from the surface inwards. The microwaves penetrate all parts of the material simultaneously, resulting in a far quicker drying time while using significantly less energy.

Our industrial microwave technology offers stark advantages over conventional heating:

100% Capital costs can be recovered via Corporation Tax through Energy Efficiency Financing

Reduced Process Times by up to 75%

Reduced Energy Costs by up to 80%

Reduced CO2 Emissions by up to 75%

Additional benefits of our microwave technology

Dielectric heating applies whenever material with low thermal and electrical conductivity is being considered and where it is profitable to use fast and deeply penetrating heating.
The industrial solutions are based on unique proprietary expertise and technology. The installations deliver:

  • robust technology
  • increased throughput ( up to 80 %) and productivity leading to,
  • safe and ‘easy-to-use’ equipment
  • low maintenance cost with easy to access equipment
  • compact solution, saving on investment cost

For reasons of energy balance or capital investment it is not always advisable to consider high frequency heating in conjunction with other energy transfer techniques as a more realistic solution.
In most applications we can consider drying and heating processes.
In case of removing the last percentage of water conventional processes are less and less efficient when the water content decreases below a certain amount.

Choice of installation

The definition of an application system is the result of a double compromise.
There is a compromise between the dielectric loss of the product (e r, tg d) and the penetration of the waves. There is a compromise between the technology of materials and that of the process to be used.

  • The principle elements to be considered are:
  • The loss factor
  • The dimensions and shapes of the product
    The cost of the installation

As far as the loss factor concerns there is a correlation between speed and uniformity of heating.
If the product is a good absorber of radiation, the penetration depth is small so that radiation does not penetrate to the centre, which means an inhomogeneous heating and therefore a reduction of the speed of heating that is not compensated by thermal conduction or direct heating.
It is also possible to use lower frequencies for high loss factor products and higher frequencies for low loss factors.
