Welcome to Koral Associates



We specialise in providing impartial technical and commercial advice relating to Radio Frequency (RF) Heating and Drying Equipment and Applications and also for related processes such as Microwave and Induction Heating.

With experience of over 50 years involvement with machine design for a very broad range of Heating, Drying  and other Applications,  we are well qualified to offer technical  and commercial advice and assistance concerning all aspects of this interesting  and exciting technology.

We are strictly independendent,  having no allegiance to any manufacturer, so we are able to give a clear opinion regarding the design, technical aspects and suitability  of any particular machine to your process.


It may not be always be necessary to visit your location in order to advise you. We have several clients who we deal with exclusively by EMail, on Skype or by other means. This can save you considerable costs in unnecessary flights, hotel expenses and labour time etc. Our extensive knowledge of RF Heating means that if you are able to describe the problem or project in words or by photograph or video, then an expensive visit to site can often be avoided!

We look forward to discussing your specific requirements.
